&amp;#039;&amp;#039;&amp;#039;Adams County&amp;#039;&amp;#039;&amp;#039; is a [[County (United States)|county]] in the [[U.S. state]] of [[Washington (state)|Washington]]. As of the [[2020 United States census|2020 census]], the population was 20,613.&amp;lt;ref name=&amp;quot;QF&amp;quot;&amp;gt;{{Cite web |title=State &amp;amp; County QuickFacts |url=https://www.census.gov/quickfacts/fact/table/adamscountywashington/PST045223 |access-date=November 9, 2024 |publisher=United States Census Bureau}}&amp;lt;/ref&amp;gt; The county seat is at [[Ritzville, Washington|Ritzville]], and its largest city is [[Othello, Washington|Othello]]. The county was formed out of [[Whitman County, Washington|Whitman County]] in November 1883&amp;lt;ref&amp;gt;{{Cite web |date=March 6, 2003 |title=Milestones for Washington State History &amp;amp;mdash; Part 2: 1851 to 1900 |url=http://www.historylink.org/essays/output.cfm?file_id=5380 |publisher=[[HistoryLink.org]]}}&amp;lt;/ref&amp;gt; and is named after [[John Adams]], the second [[President of the United States]]. Adams County&amp;#039;s two most populous cities are Ritzville and Othello. Ritzville is located in the northeastern corner of the county at the junction of I-90 and US 395, making it a popular stop for travelers. Ritzville is an hour&amp;#039;s drive from [[Spokane, Washington|Spokane]]. Othello is located in the southwestern panhandle of the county.&lt;br /&gt;
&lt;br /&gt;
==History==&lt;br /&gt;
&lt;br /&gt;
=== Incorporation ===&lt;br /&gt;
The Governor of Washington Territory approved the proposed Adams County Articles of Incorporation on November 28, 1883. At that time Adams County and [[Franklin County, Washington|Franklin County]] were formed out of territory from [[Whitman County, Washington|Whitman County]]. The first County meeting (December 19, 1883) established Ritzville as the county seat.&lt;br /&gt;
&lt;br /&gt;
By 1885, the county offices were established, in a wood-frame house purchased for the purpose in Ritzville.&lt;br /&gt;
[[File:Adams County Courthouse, Ritzville, Washington, circa 1892.jpg|left|thumb|(Second) County Courthouse in Ritzville, completed on August 20, 1892.]]&lt;br /&gt;
The 1890 census showed that Adams County boasted 2,098 residents. The growing population justified a purpose-built courthouse, so construction began on a new brick courthouse on February 23, 1892.&amp;lt;ref name=&amp;quot;:0&amp;quot;&amp;gt;{{Cite web |title=National Register of Historic Places |url=https://dahp.wa.gov/sites/default/files/WA_Adams%20County%20Courthouse_NR_FINAL.pdf |access-date=2025-06-16 |website=[[United States Department of the Interior]] [[National Park Service]] [[Washington Department of Archaeology and Historic Preservation]]}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== 20th century ===&lt;br /&gt;
Wheat farming was a main focus of early residents. By 1904, [[Ritzville, Washington|Ritzville]] had become the largest initial shipping point for wheat in the United States;&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&amp;lt;ref&amp;gt;{{Cite web |title=History of Adams County, Washington |url=https://genealogytrails.com/wash/adams/history_county.html |access-date=2025-06-16 |website=genealogytrails.com}}&amp;lt;/ref&amp;gt; a 1909 pamphlet at the [[Alaska–Yukon–Pacific Exposition|Alaska-Yukon-Pacific Exposition]] in [[Seattle]] read:&amp;lt;blockquote&amp;gt;&amp;#039;&amp;#039;Adams County, Washington, the bread basket of the world. A land of wonderful resources where courage, intelligence, strenuous and persistent efforts of the hardy pioneer have wrested the hidden wealth from mother earth ... [a] golden wheat belt which has pushed its way steadily into the wilderness of sage brush which the pioneers found when they came. The gold has gradually absorbed the brown ... the history of Adams County is a song of wheat.&amp;#039;&amp;#039;&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&amp;lt;/blockquote&amp;gt;&lt;br /&gt;
[[File:Adams County Courthouse, Ritzville, Washington, circa 1915.jpg|left|thumb|Courthouse after expansion, circa 1915.]]&lt;br /&gt;
In May 1905, under pressure from citizens of the county, an addition to the courthouse was designed by Spokane architects [[Herman Preusse|Preusse &amp;amp; Zittel]], doubling its square footage, and moving the edge of the building to the sidewalk on West Broadway Ave.; the bell tower was dismantled. [[Spokane, Washington|Spokane]] contractors Hastie &amp;amp; Dougan supervised the project, which began in June and was completed in October for a cost of $12,247.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Wheat producers in Adams County used [[dryland farming]] in order to overcome the relative aridity of the county&amp;#039;s climate. They let the wheatfields lie fallow in alternate years, holding sufficient moisture to raise profitable crops.&lt;br /&gt;
&lt;br /&gt;
The county&amp;#039;s population decreased significantly during the first half of the twentieth century, dropping by nearly five thousand from 1910 to 1940.&lt;br /&gt;
&lt;br /&gt;
In 1940 the courthouse was replaced by a three-story building, with a two-story jail at the rear. Construction was completed in December 1940.&lt;br /&gt;
&lt;br /&gt;
In 1943 the Federal government approved the [[Columbia Basin Project]]. It began impacting Adams County in 1946, when construction of the East Low Canal and the Potholes East Canal began. This work, and the ensuing increased agricultural production from irrigated crops, led to continual population increases. The population had increased by 12,500 from 1940 to 2010.&amp;lt;ref&amp;gt;[http://www.co.adams.wa.us/residents/about_adams_county/index.php &amp;#039;&amp;#039;About Adams County&amp;#039;&amp;#039;]&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Geography==&lt;br /&gt;
According to the [[United States Census Bureau]], the county has a total area of {{convert|1929.802|sqmi}}, of which {{convert|1924.989|sqmi}} is land and {{convert|4.813|sqmi}} (0.3%) is water.&amp;lt;ref&amp;gt;{{Cite web|title=2024 County Gazetteer Files – Minnesota|url=https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/2024_gaz_counties_53.txt|publisher=[[United States Census Bureau]]|access-date=November 20, 2024}}&amp;lt;/ref&amp;gt;&lt;br /&gt;

==Politics==&lt;br /&gt;
Adams is a strongly [[Republican Party (United States)|Republican]] county. The last Democrat to win the county was [[Franklin D. Roosevelt]] [[1936 United States presidential election|in 1936]].&amp;lt;ref&amp;gt;{{Cite web |title=Presidential election of 1936 - Map by counties |url=http://geoelections.free.fr/USA/elec_comtes/1936.htm |access-date=April 5, 2018 |website=geoelections.free.fr}}&amp;lt;/ref&amp;gt; It was one of only three counties in the state to be won by [[Barry Goldwater]] in 1964. Adams County&amp;#039;s unbroken streak of Republican votes in presidential elections is the longest of any county in Washington.&amp;lt;ref&amp;gt;[http://www.uselectionatlas.org/RESULTS/comparemaps.php?year=1964&amp;amp;fips=53&amp;amp;f=1&amp;amp;off=0&amp;amp;elect=0 David Leip’s Presidential Atlas (Maps for Washington by election)]&amp;lt;/ref&amp;gt; The Republican candidate has won by more than 13 points in every Presidential election since 1968, with margins of over 30 points in the seven presidential elections since 2000. [[George W. Bush]] won the county by over 40 points both times he ran.&amp;lt;ref&amp;gt;[http://elections.nytimes.com/2008/results/president/map.html?scp=1&amp;amp;sq=%22election%20map&amp;amp;st=cse The New York Times Electoral Map (Zoom in on Washington state)]&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In other elections the results fare similarly. The last Democratic candidate for governor to carry Adams County was [[Clarence D. Martin]] in 1936.&amp;lt;ref&amp;gt;[http://www.uselectionatlas.org/RESULTS/comparemaps.php?year=2008&amp;amp;fips=53&amp;amp;f=1&amp;amp;off=5&amp;amp;elect=0 David Leip&amp;#039;s US Election Atlas (Washington state maps)]&amp;lt;/ref&amp;gt; The last Democratic candidate for the U.S. Senate to win the county was [[Henry M. Jackson]] in 1982.&amp;lt;ref&amp;gt;[http://www.uselectionatlas.org/RESULTS/comparemaps.php?year=2010&amp;amp;fips=53&amp;amp;f=1&amp;amp;off=3&amp;amp;elect=0 David Leip&amp;#039;s US Election Atlas (Washington state maps)]&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the 2008 presidential election, [[John McCain]] received 66.32% of the county&amp;#039;s vote. Meanwhile, Republican gubernatorial candidate [[Dino Rossi]] received 69.83% of the county&amp;#039;s vote. The county also gave Republican representative [[Cathy McMorris Rodgers]] 82.45% of the vote. Republican [[Sam Reed]] received 74.6% of the county&amp;#039;s vote in his run for re-election as [[Secretary of State of Washington|Washington Secretary of State]], Republican Allan Martin received 67.25% of the vote for state treasurer, and Republican [[Rob McKenna]] received 76.28% in his re-election run for attorney general. All county positions for which candidates were affiliated with parties were won by Republicans.&amp;lt;ref&amp;gt;[http://wei.secstate.wa.gov/ADAMS/ELECTIONS/Pages/ElectionResults.aspx Election results for Adams County at Washington governmental site] {{webarchive |url=https://web.archive.org/web/20081208224346/http://wei.secstate.wa.gov/ADAMS/ELECTIONS/Pages/ElectionResults.aspx|date=December 8, 2008}}&amp;lt;/ref&amp;gt;&lt;br /&gt;

==Courthouses==&lt;br /&gt;
From Ritzville&amp;#039;s designation as county seat in 1884 until 1892, courts were briefly held in rented space before the county purchased a building from N.H. Greene in 1885. In 1891 the commission bonded $20,000 in order to erect a permanent courthouse. The building was built by the [[Spokane]] firm of Burnham and Clapp and completed by August 20, 1891, when it was accepted by the county. It was a two-story brick building with a four-story tower and a stone basement. A two-story addition was added to the front in 1905 with a new four-story tower, giving the courthouse a whole new appearance. This building was replaced by the current art-deco courthouse in 1940.&lt;br /&gt;
