The '''history of Guam''' starts with the early arrival around 2000 BC of [[Austronesian people]] known today as the [[Chamorro people|Chamorro Peoples]]. The Chamorus then developed a "pre-contact" society, that was [[Spanish Empire|colonized by the Spanish]] in the 17th century. The present [[United States|American]] rule of the island began with the 1898 [[Spanish–American War]]. [[Guam|Guam's]] history of [[colonialism]] is the longest among the Pacific islands.

Archeological studies of human activity on the islands has revealed potteries with red-slipped, circle-stamped and punctate-stamped designs found in the Mariana Islands dating between 1500 and 1400 BC.

[[Human mitochondrial genetics|Mitchondrial DNA]] and [[whole genome sequencing]] of the Chamoru people strongly support Philippine ancestry. Genetic analysis of pre-[[Latte stone|''Latte'' period]] skeletons in Guam also show that they do not have [[Melanesians|Melanesian]] ancestry which rules out origins from the [[Bismarck Archipelago]], [[New Guinea]], or eastern [[Indonesia]]. The [[Lapita culture]] itself (the ancestral branch of the Polynesian migrations) is younger than the first settlement of the Marianas (the earliest Lapita artifacts are dated to around 1350 to 1300 BCE), indicating that they originated from separate migration voyages.<ref name="Pugach">{{cite journal |last1=Pugach |first1=Irina |last2=Hübner |first2=Alexander |last3=Hung |first3=Hsiao-chun |last4=Meyer |first4=Matthias |last5=Carson |first5=Mike T. |last6=Stoneking |first6=Mark |title=Ancient DNA from Guam and the Peopling of the Pacific |journal=bioRxiv |date=14 October 2020 |volume=118 |issue=1 |article-number=2020.10.14.339135 |doi=10.1101/2020.10.14.339135|pmid=33443177 |pmc=7817125 |hdl=21.11116/0000-0007-9BA4-1 |s2cid=224817625 |hdl-access=free }}</ref><ref name="Vilar">{{cite journal |last1=Vilar |first1=Miguel G. |last2=Chan |first2=Chim W |last3=Santos |first3=Dana R |last4=Lynch |first4=Daniel |last5=Spathis |first5=Rita |last6=Garruto |first6=Ralph M |last7=Lum |first7=J Koji |title=The origins and genetic distinctiveness of the chamorros of the Marianas Islands: An mtDNA perspective |journal=American Journal of Human Biology |date=January 2013 |volume=25 |issue=1 |pages=116–122 |doi=10.1002/ajhb.22349|pmid=23180676 |pmc=4335639 }}</ref>

Nevertheless, DNA analysis also shows a close genetic relationship between ancient settlers of the Marianas and early Lapita settlers in the [[Bismarck Archipelago]]. This may indicate that both the Lapita culture and the Marianas were settled by direct migrations from the Philippines, or that early settlers from the Marianas voyaged further southwards into the Bismarcks and reconnected with the Lapita people.<ref name="Pugach"/>

The Marianas also later established contact and received migrations from the [[Caroline Islands]] at around the first millennium CE. This brought new pottery styles, language, genes, and the hybrid Polynesian [[breadfruit]].<ref name="Peterson">{{cite journal |last1=Peterson |first1=John A. |title=Latte villages in Guam and the Marianas: Monumentality or monumenterity? |journal=Micronesica |date=2012 |volume=42 |issue=1/2 |pages=183–208 |url=https://micronesica.org/sites/default/files/5_smpeterson_pp183-208.pdf |archive-url=https://web.archive.org/web/20170820002325/http://micronesica.org/sites/default/files/5_smpeterson_pp183-208.pdf |archive-date=2017-08-20 |url-status=live}}</ref>

The period 900 to 1700 CE of the Marianas, immediately before and during the Spanish colonization, is known as the [[Latte stone|''Latte'' period]]. It is characterized by rapid cultural change, most notably by the massive [[megalithic]] ''latte'' stones (also spelled ''latde'' or ''latti''). These were composed of the ''haligi'' pillars capped with another stone called ''tasa'' (which prevented rodents from climbing the posts). These served as supports for the rest of the structure which was made of wood. Remains of structures made with similar wooden posts have also been found. Human graves have also been found in front of ''latte'' structures. The ''Latte'' period was also characterized by the introduction of [[rice]] agriculture, which is unique in the pre-contact [[Pacific Islands]].<ref name="Laguana"/>

The reasons for these changes are still unclear, but it is believed that it may have resulted from a third wave of migrants from [[maritime Southeast Asia]]. Comparisons with other architectural traditions makes it likely that this third migration wave were again from the Philippines, or from eastern [[Indonesia]] (either [[Sulawesi]] or [[Sumba]]), all of which have a tradition of raised buildings with capstones. Interestingly, the word ''haligi'' ("pillar") is also used in various languages throughout the Philippines; while the Chamoru word ''guma'' ("house") closely resembles the Sumba word ''uma''.<ref name="Laguana">{{cite journal |last1=Laguana |first1=Andrew |last2=Kurashina |first2=Hiro |last3=Carson |first3=Mike T. |last4=Peterson |first4=John A. |last5=Bayman |first5=James M. |last6=Ames |first6=Todd |last7=Stephenson |first7=Rebecca A. |last8=Aguon |first8=John |last9=Harya Putra |first9=Ir.

===Ancient Chamoru society===
[[File:Ancient Chamorro Society - Pellion - .jpg|thumb|1819 illustration depicting the three Chamoru castes]]
Most of what is known about Pre-Contact ("Ancient") Chamorus comes from legends and myths, archaeological evidence, [[Jesuit]] [[missionary]] accounts, and observations from visiting scientists like [[Otto von Kotzebue]] and [[Louis de Freycinet]].

When Europeans first arrived on Guam, Chamoru society roughly fell into three classes: ''matao'' (upper class), ''achaot'' (middle class), and ''mana'chang'' (lower class). The matao lived in the coastal villages, which meant they had the best access to fishing grounds while the mana'chang lived in the interior of the island. Matao and mana'chang rarely communicated with each other, and matao often used achaot as a go-between.

There were also "makhanas" (shamans) and "suruhanus" (herb doctors), skilled in healing and medicine.<ref>{{Cite book|url=https://books.google.com/books?id=9r0a2ww8KLcC&pg=PA101|title=Ancient Chamorro Society|last=Cunningham|first=Lawrence J.|date=1992-01-01|publisher=Bess Press|isbn=978-1-880188-05-7|language=en}}</ref> Belief in spirits of ancient Chamorros called ''[[Taotao Mona]]'' still persists as remnant of pre-European society. Early European explorers noted the [[sakman]], the Chamoru fast sailing vessel used for trading with other islands of Micronesia.

===Latte===
[[File:HaputoBeachSite.jpg|thumb|[[Latte stone]] from a northern beach]]
The [[latte stones]] were not a recent development in Contact Chamoru society. The latte stone consists of a head and a base shaped out of limestone. Like the [[Easter Island]] [[Moai]] statues, there is plenty of speculation over how this was done by a society without machines or metal, but the generally accepted view is that the head and base were etched out of the ground by sharp adzes and picks (possibly with the use of fire), and carried to the assembly area by an elaborate system of ropes and logs. The latte stone was used as a part of the raised foundation for a magalahi (matao chief) house, although they may have also been used for canoe sheds.

Archaeologists using carbon-dating have broken Pre-Contact Guam (i.e. Chamoru) history into three periods: "Pre-Latte" (BC 2000? to AD 1) "Transitional Pre-Latte" (AD 1 to AD 1000), and "Latte" (AD 1000 to AD 1521). Archaeological evidence also suggests that Chamoru society was on the verge of another transition phase by 1521, as latte stones became bigger.

Assuming the stones were used for chiefly houses, it can be argued that Chamoru society was becoming more stratified, either from population growth or the arrival of new people. The theory remains tenuous, however, due to lack of evidence, but if proven correct, will further support the idea that Pre-Contact Chamorus lived in a vibrant and dynamic environment. <!-- Society becoming more stratified does not mean that it is dynamic or vibrant. Besides, this part is in dire need of inline citations. -->

=== Magellan's first encounter with Guam ===
[[File:Reception of the Manila Galleon by the Chamorro in the Ladrones Islands, ca. 1590.jpg|thumb|left|Reception of the [[Manila galleon|Manila Galleon]] by the [[Chamorro people|Chamoru]] in the [[Mariana Islands|Ladrones Islands]], ca. 1590 [[Boxer Codex]]]]
The first known contact between [[Guam]] and Europeans occurred with the arrival of a Spanish expedition led by [[Ferdinand Magellan]]. His three-ship fleet arrived on March 6, 1521, after a long voyage across the Atlantic and Pacific Oceans, from Spain. History credits the village of [[Umatac, Guam|Umatac]] as his landing place, but drawings from the navigator's diary suggest that Magellan may have landed in [[Tumon]] in northern Guam. The expedition had started out in Spain with five ships. By the time they reached the Marianas, they were down to three ships and barely half the crew, due to storms, disease, and mutiny in one ship.<ref name="Pacific Worlds">[http://www.pacificworlds.com/guam/visitors/explore.cfm Pacific Worlds], Antonio Pigafetta's account.</ref>

When Magellan's fleet arrived at Guam, they were greeted by hundreds of small [[outrigger canoe]]s that appeared to be flying over the water due to their considerable speed. These outrigger canoes were called [[proa]]s and resulted in Magellan naming Guam ''Islas de las Velas Latinas'' ("Islands of the [[Lateen sail]]s"). [[Antonio Pigafetta]] (one of  18 crewmen who completed the voyage) wrote in his account that the name was "Island of Sails".

Tired and hungry from their long voyage, the crew prepared to go ashore and get food and water. However, the Chamorus had a different concept of ownership, based on subsistence living, and were very excited by the appearance of these strange vessels.<ref name=Rodgers>{{Cite book

After a few shots were fired from the [[Trinidad (ship)|''Trinidad'']]'s big guns, the natives were frightened off from the ship and retreated into the surrounding jungle. Magellan was eventually able to obtain rations and offered iron, a highly prized material, in exchange for fresh fruits, vegetables, and water. Details of this visit, the first in history between the Spanish and a Pacific island people, come from Pigafetta's journal.<ref name="Pacific Worlds" />

Despite Magellan's visit, Guam was not officially claimed by Spain until 1565 by [[Miguel Lopez de Legazpi]].

On June 15, 1668, the [[galleon]] ''San Diego'' arrived at the island of Guam.<ref name="History of Guam Book">Lawrence J Cunningha, Janice J. Beaty. ''History of Guam''.</ref> [[Jesuit]] missionaries led by [[Diego Luis de San Vitores]] arrived on Guam to introduce [[Christianity]] and develop trade. The Spanish taught the Chamorus to cultivate [[maize]] (corn), raise cattle, and tan hides, as well as to adopt western-style clothing. They also introduced the Spanish language and culture. Once Christianity was established, the Catholic Church became the focal point for village activities, as in other Spanish cities. Since 1565, Guam had been a regular port-of-call for the Spanish galleons that crossed the Pacific Ocean from [[Mexico]] to the [[Philippines]].<ref name="Guam Online">[https://guam-online.com/history/ Brief History of Guam]. Guam Online</ref>

[[Chief Quipuha]] was the maga'lahi, or high ranking male, in the area of Hagåtña when the Spanish landed there in 1668. Quipuha welcomed the missionaries and consented to be baptized by Fr. San Vitores as Juan Quipuha. Quipuha granted the lands on which the first Catholic Church in Guam was constructed in 1669. Chief Quipuha died in 1669 but his policy of allowing the Spanish to establish a base on Guam had important consequences for the future of the island. It also facilitated the Manila [[Galleon trade]].

A few years later, Fr. San Vitores and his assistant, [[Pedro Calungsod]], were killed by Chief [[Matapang|Mata'pang]] of Tomhom ([[Tumon]]), allegedly for baptizing the Chief's baby girl without the Chief's consent. This was in April 1672. Many Chamorus at the time believed baptisms killed babies: because priests would baptize infants already near death (in the belief that this was the only way to save such children's souls), baptism seemed to many Chamorus to be the cause of death.{{r|Rodgers}}{{rp|49}} The death of Quipuha, and the murder of San Vitores and Calungsod, led to a number of conflicts.

During this historical period, Spanish language and customs were introduced in the island and [[Catholicism]] became the predominant religion. The Spanish built infrastructures such as roads and ports, as well as schools and hospitals. Spanish and Filipinos, mostly men, increasingly intermarried with the Chamorus, particularly the new cultured or "high" people (''manak'kilo'') or gentry of the towns. In 1740, Chamorus of the Northern Mariana Islands, except [[Rota (island)|Rota]], were moved from some of their home islands to Guam.

Following the German defeat in [[World War I]], the [[Northern Mariana Islands]] became part of the [[South Seas Mandate]], a [[League of Nations]] Mandate in 1919 with the nearby [[Empire of Japan]] as the mandatory ("trustee") as a member nation of the victorious [[Allies of World War I|Allies]] in the "Great War".<ref name="Rogers2"/> The 1910 [[Catholic Encyclopedia]] said of Guam, "of its total population of 11,490 (11,159 natives), [[Hagåtña]], the capital, contains about 8,000. Possessing a good harbor, the island serves as a United States [[Apra Harbor|naval station]], the naval commandant acting also as [[governor]]. The products of the island are [[maize]], [[copra]], [[rice]], [[sugar]], and valuable [[timber]]." [[Governor of Guam|Military officers governed the island]] as "USS ''Guam''", and the [[United States Navy]] opposed proposals for civilian government until 1950.{{r|Rodgers}}{{rp|125–126}}

===World War II===
[[File:1944 Guam Plaza de Espana.jpg|thumb|[[United States Marine Corps|Marines]] before the ruins of the church in [[Hagåtña, Guam|Hagåtña]] during the [[Battle of Guam (1944)|liberation of Guam]] in 1944.]]
{{Main|Japanese occupation of Guam}}
{{Further|Pacific Islands home front during World War II}}
During [[World War II]], Guam was [[Battle of Guam (1941)|attacked and invaded]] by [[Empire of Japan|Japan]] on Monday, December 8, 1941, at the same time as the [[attack on Pearl Harbor]], across the International Date Line. In addition, Japan made major military moves into Southeast Asia and the [[East Indies]] islands of the South Pacific Ocean against the British and Dutch colonies, opening a new wider Pacific phase in the Second World War. The Japanese renamed Guam {{lang|ja-Latn|Ōmiya-jima}} (Great Shrine Island).

The [[Northern Mariana Islands]] had become a League of Nations mandate assigned to Japan in 1919, pursuant to the [[Treaty of Versailles]] of 1919. Indigenous [[Chamorro people]] from the Northern Marianas were brought to Guam to serve as interpreters and in other capacities for the occupying Japanese force. The Guamanian Chamorros were treated as an occupied enemy by the Japanese military. After the war, this would cause resentment between the Guamanian Chamorros and the Chamorros of the Northern Marianas. Guam's Chamorros believed their northern brethren should have been compassionate towards them, whereas having been administered by Japan for over 30 years, the Northern Mariana Chamorros were loyal to the Japanese government.<ref>{{Cite web |date=2009-10-01 |title=Chamorus: A People Divided - Guampedia |url=https://www.guampedia.com/chamorros-a-people-divided/ |access-date=2024-05-16 |website=www.guampedia.com |language=en-US}}</ref>

The [[Japanese occupation of Guam]] lasted for approximately 31 months, from 1941 to 1944.<ref>Wakako Higuchi, ''The Japanese Administration of Guam, 1941-1944: A Study of Occupation and Integration Policies, with Japanese Oral Histories'' (Jefferson  McFarland, 2013); [https://www.h-net.org/reviews/showrev.php?id=38466  online review]</ref> During this period, the indigenous people of Guam were subjected to forced labor, family separation, incarceration, execution, concentration camps and forced prostitution. Approximately 1,000 people died during the occupation, according to later [[United States Congress|Congressional]] committee testimony in 2004. Some historians estimate that war violence killed 10% of Guam's then 20,000 population.<ref>Werner Gruhl, ''[https://books.google.com/books?id=ow5Wlmu9MPQC&pg=PA102 Imperial Japan's World War Two, 1931–1945] {{webarchive|url=https://web.archive.org/web/20160101014017/https://books.google.com/books?id=ow5Wlmu9MPQC&pg=PA102|date=January 1, 2016}}'', Transaction Publishers, 2007 {{ISBN|978-0-7658-0352-8}}</ref> It was a coercive experience for the Chamoru people, whose loyalty to the United States became a point of contention with the Japanese. Several American servicemen remained on the island, however, and were hidden by the Chamoru people. All of these servicemen were found and executed by Japanese forces in 1942; only one escaped.

[[File:Women washing clothes in a river near Hagåtña on 12 August 1944.jpg|thumb|Women washing clothes in a river at [[Hagåtña, Guam|Hagåtña]] next to trees destroyed by the bombardment, August 1944]]
The second [[Battle of Guam (1944)|Battle of Guam]] began on July 21, 1944, with American troops landing on western side of the island after several weeks of pre-invasion bombardment by the U.S. Navy. After several weeks of heavy fighting, Japanese forces officially surrendered on August 10, 1944. More than 18,000 Japanese were killed as only 485 surrendered. Sergeant [[Shoichi Yokoi]], who surrendered in January 1972, appears to have been the last confirmed [[Japanese holdout]], having held out for 28 years in the forested back country on Guam.<ref>{{cite news|last=Kristofferson|first=Nicholas D.|url=https://query.nytimes.com/gst/fullpage.html?res=950DE7D81F3BF935A1575AC0A961958260|title=Shoichi Yokoi, 82, Is Dead; Japan Soldier Hid 27 Years|work=The New York Times|date=September 26, 1997|url-status=live|archive-url=https://web.archive.org/web/20090201172619/http://query.nytimes.com/gst/fullpage.html?res=950DE7D81F3BF935A1575AC0A961958260|archive-date=February 1, 2009}}</ref> The United States also captured and occupied the nearby Northern Marianas Islands.

Guam was subsequently converted into a forward operations base for the U.S. Navy and Air Force. Airfields were constructed in the northern part of the island (including [[Andersen Air Force Base]]), the island's pre-WWII [[Naval Base Guam|Naval Station]] was expanded, and numerous facilities and supply depots were constructed throughout the island. North Field was established in 1944, and was renamed for Brigadier General [[James Roy Andersen]] of the old [[United States Army Air Forces|U.S. Army Air Forces]] as [[Andersen Air Force Base]].

Guam's two largest pre-war communities ([[Sumay, Guam|Sumay]] and [[Hagåtña]]) were virtually destroyed during the 1944 battle. Many Chamoru families lived in temporary re-settlement camps near the beaches before moving to permanent homes constructed in the island's outer villages. Guam's southern villages largely escaped damage, however.

===Self-determination===
[[File:Antonio Won Pat.png|thumb|upright|Prior to becoming the first [[Delegate (United States Congress)|Delegate]] from Guam to the [[United States House of Representatives]] in 1973, [[Antonio Borja Won Pat]] actively lobbied for Guam's self-representation]]
The immediate years after [[World War II]] saw the [[United States armed forces|U.S. Navy]] attempting to resume its predominance in Guam affairs. This eventually led to resentment, and thus increased political pressure from Chamoru leaders for greater autonomy.

The result was the [[Guam Organic Act of 1950]] which established Guam as an unincorporated [[organized territory]] of the United States and, for the first time in Guam history, provided for a civilian government. In 1951, Public Law 01-12 established the new government, including a judicial branch, and an executive branch with many departments.{{Efn|Created agencies included the Department of Medical Services, the [[Guam Department of Public Works|Department of Public Works]], the [[Guam Department of Education|Department of Education]], the Department of Public Safety, the Division of Civil Defense, the Department of Finance, the Office of the Commissioners of Guam, the [[Office of Attorney General of Guam|Department of Attorney General]], the [[Guam Department of Agriculture|Department of Agriculture]], the Department of Labor and Personnel, the [[Governor of Guam|Governor's Office]], the [[Guam Department of Land Management|Office of Land Management]], the Budget Office, the Department of Commerce, the Alcoholic Beverage Control Board, and the Office of Election Commissioner.}}<ref name="PublicLaw12">{{Cite law|title=Public Law 12|orig-date=1951-04-24|authority=First Guam Legislature}}</ref>

The [[Immigration and Nationality Act of 1952]], section 307, granted [[U.S. citizenship]] to "all persons born in the island of Guam on or after April 11, 1899. In the 1960s, the island's required [[security clearance]] for visitors was lifted.

On September 11, 1968, eighteen years after passage of the Organic Act, Congress passed the "[[Elective Governor Acts of 1968|Elective Governor Act]]" (Public Law 90-497), which allowed the people of Guam to elect their own governor and lieutenant governor. Nearly four years later, Congress passed the "Guam-Virgin Islands Delegate" Act that allowed for one Guam delegate in the U.S. House of Representatives. The delegate has a voice in debates and a vote in committees, but no vote on the floor of the House.

Andersen Air Force Base played a major role in the [[Vietnam War]]. The host unit was later designated the [[36th Wing#Pacific Air Forces|36th Wing]] (36 WG), assigned to the [[Pacific Air Forces]] (PACAF) [[Thirteenth Air Force]] (13AF). In September 2012, 13 AF was deactivated and its functions merged into PACAF. The multinational [[Cope North]] military exercise is an annual event.<ref>[https://www.postguam.com/news/local/us-japan-australia-to-hold-cope-north/article_97099f96-edd5-11e6-9b56-ef2a341c3941.html US, Japan, Australia to hold Cope North 2017 February 9, 2017] ''Guam Post'' Retrieved March 27, 2017.</ref>

Although Public Law 94-584 established the formation of a "locally drafted" constitution (later known as the "Guam Constitution"), the proposed document was rejected by Guam residents in an [[Guamanian constitutional referendum, 1979|August 4, 1979 referendum]].

In the meantime, Guam's local government had formed several political status commissions to address possible options for [[self-determination]]. The following year after passage of the Guam Delegate Act saw the creation of the "Status Commission" by the Twelfth Guam Legislature.

This was followed by the establishment of the "Second Political Status Commission" in 1975 and the Guam "Commission on Self-Determination" (CSD) in 1980. The Twenty-Fourth Guam Legislature established the "Commission on Decolonization" in 1996 to enhance CSD's ongoing studies of various political status options and public education campaigns.

These efforts enabled the CSD, barely two years after its creation, to organize a [[Guamanian status referendum, January 1982|status referendum]] on January 12, 1982. 49% of voters chose a closer relationship with the United States via [[Commonwealth (U.S. insular area)|Commonwealth]].

Twenty-six percent voted for Statehood, while ten percent voted for the Status Quo (as an Unincorporated territory). A [[Guamanian status referendum, September 1982|subsequent run-off referendum]] held between Commonwealth and Statehood saw 73% of Guam voters choosing Commonwealth over Statehood (27%). Today, Guam remains an unincorporated territory despite referendums and a United Nations mandate to establish a permanent status for the island.{{Citation needed|reason=reliable source needed for the whole sentence|date=August 2012}}

Guam's [[U.S. military]] installations remain among the most strategically vital in the [[Pacific Ocean]]. When the United States closed [[U.S. Naval Base Subic Bay]] and [[Clark Air Base]] bases in the [[Philippines]] after the expiration of their leases in the early 1990s, many of the forces stationed there were relocated to Guam.

The removal of Guam's security clearance by President John F. Kennedy in 1963 allowed for the development of a [[tourism]] industry. The island's rapid economic development was fueled both by rapid growth in this industry as well as increased U.S. Federal Government spending during the 1980s and 1990s.{{Citation needed|reason=reliable source needed for the whole sentence|date=July 2012}}

The [[1997 Asian financial crisis]], which hit Japan particularly hard, severely affected Guam's tourism industry. Military cutbacks in the 1990s also disrupted the island's economy. Economic recovery was further hampered by devastation from Supertyphoons [[Typhoon Paka|Paka]] in 1997 and [[Typhoon Pongsona|Pongsona]] in 2002, as well as the effects of the [[September 11, 2001 attacks|September 11 terrorist attacks]] on tourism.

The recovery of the Japanese and Korean tourist markets reflected those countries' economic recoveries, as well as Guam's continued appeal as a weekend tropical retreat. U.S. military spending also dramatically increased as part of the [[War on Terrorism]].

The late 2000s saw proposals to strengthen U.S. military facilities, including negotiations to transfer 8,000 [[U.S. Marine Corps|U.S. Marines]] from [[Okinawa Prefecture|Okinawa]]. American forces were originally scheduled to relocate from Okinawa to Guam beginning in 2012 or 2013. However, that was set back due to budget constrains and local resistance to the additional military presence; [[Marine Corps Base Camp Blaz]] was activated in 2020 but the relocation is scheduled to start no later than by the first half of the 2020s.

"Cosmopolitan" Guam poses particular challenges for Chamorus struggling to preserve their culture and identity in the face of [[acculturation]].
