The '''gens Claudia''' ({{IPA|la|ˈkɫau̯di.a|lang}}), sometimes written '''Clodia''', was one of the most prominent [[patrician (ancient Rome)|patrician]] houses at [[ancient Rome]].  The [[gens]] traced its origin to the earliest days of the [[Roman Republic]].  The first of the Claudii to obtain the [[Roman consul|consulship]] was [[Appius Claudius Sabinus Regillensis]], in 495 BC, and from that time its members frequently held the highest offices of the state, both under the Republic and in [[Roman Empire|imperial times]].<ref name="DGRBM Claudia Gens">''Dictionary of Greek and Roman Biography and Mythology'', vol. I, p. 762 ("[[s:Dictionary of Greek and Roman Biography and Mythology/Claudia gens|Claudia Gens]]").</ref>

[[Plebeian]] Claudii are found fairly early in Rome's history. Some may have been descended from members of the family who had passed over to the plebeians, while others were probably the descendants of [[freedman|freedmen]] of the gens.<ref name="DGRBM Claudia Gens"/> In the later Republic, [[Publius Clodius Pulcher|one of its patrician members]] voluntarily converted to plebeian status and adopted the spelling "[[Clodius]]".

In his life of the emperor [[Tiberius]], who was a scion of the Claudii, the historian [[Suetonius]] gives a summary of the gens, and says, "as time went on it was honoured with twenty-eight consulships, five dictatorships, seven censorships, six triumphs, and two ovations."  Writing several decades after the fall of the so-called "[[Julio-Claudian dynasty]]", Suetonius took care to mention both the good and wicked deeds attributed to members of the family.<ref>Suetonius, "The Life of Tiberius", 1–3.</ref>

The patrician Claudii were noted for their pride and arrogance, and intense hatred of the commonalty.  In his ''History of Rome,'' [[Barthold Georg Niebuhr|Niebuhr]] writes,
<blockquote>That house during the course of centuries produced several very eminent, few great men; hardly a single noble-minded one.  In all ages it distinguished itself alike by a spirit of haughty defiance, by disdain for the laws, and iron hardness of heart.<ref>Niebuhr, ''History of Rome'', vol. I, p. 599.</ref></blockquote>
During the Republic, no patrician Claudius adopted a member of another gens; the emperor [[Claudius]] was the first who broke this custom, by adopting Lucius Domitius Ahenobarbus, afterwards the emperor [[Nero]].<ref name="DGRBM Claudia Gens"/><ref>Suetonius, "The Life of Claudius", 39.</ref><ref>Tacitus, ''Annales'', xii.</ref>

==Origin==
According to legend, the first of the Claudii was a [[Sabines|Sabine]], by the name of ''[[Appius Claudius Sabinus Regillensis|Attius Clausus]]'', who came to Rome with his retainers in 504 BC, the sixth year of the [[Roman Republic|Republic]].{{efn-lr|Various sources give several variations of his original praenomen and nomen, including ''Attius Clausus'',<ref name="Livy ii 16"/> ''Atta Claudius'',<ref name="Suetonius Tiberius 1"/> and ''Titus Claudius''.<ref name="Dionysius v 40"/>}}<ref name="Livy ii 16">Livy, ii. 16</ref>  At this time, the fledgling Republic was engaged in regular warfare with the Sabines, and Clausus is said to have been the leader of a faction seeking to end the conflict.  When his efforts failed, he defected to the Romans, bringing with him no fewer than five hundred men able to bear arms, according to [[Dionysius of Halicarnassus|Dionysius]].<ref name="Dionysius v 40">Dionysius, v. 40.</ref>

Clausus, who exchanged his Sabine name for the [[Latin]] ''Appius Claudius'', was enrolled among the patricians, and given a seat in the [[Roman Senate|Senate]], quickly becoming one of its most influential members.<ref name="Livy ii 16"/><ref name="Suetonius Tiberius 1">Suetonius, "The Life of Tiberius", 1.</ref>{{efn-lr|An alternative tradition, mentioned by Suetonius, asserted that the Claudii came to Rome with the Sabine king [[Titus Tatius]], during the reign of [[Romulus and Remus|Romulus]], the founder and first [[King of Rome]].<ref name="Suetonius Tiberius 1"/>}}  His descendants were granted a burial site at the foot of the [[Capitoline Hill]], and his followers allotted land on the far side of the [[Aniene|Anio]], where they formed the core of what became the "[[Roman tribe#Later tribes|Old Claudian]]" tribe.<ref name="Livy ii 16"/><ref name="Suetonius Tiberius 1"/><ref name="Dionysius v 40"/>

The emperor [[Claudius]] is said to have referred to these traditions in a speech made before the [[Roman Senate|senate]], in which he argued in favor of admitting [[Gauls]] to that body.  "My ancestors, the most ancient of whom was made at once a citizen and a noble of Rome, encourage me to govern by the same policy of transferring to this city all conspicuous merit, wherever found."<ref>Tacitus, ''Annales'', xi. 24.</ref>  By imperial times, the influence of the Claudii was so great that the poet [[Virgil]] flattered them by a deliberate anachronism.  In his ''[[Aeneid]]'', he makes Attius Clausus a contemporary of [[Aeneas]], to whose side he rallies with a host of ''quirites'', or spearmen.{{efn-lr|"Lo! Clausus of old Sabine blood, who leads a mighty host, himself a host in might! From whom the Claudian tribe and clan to-day, since Rome was with the Sabine shared, spreads wide through Latium....<ref name="Aeneid vii"/>}}<ref name="Aeneid vii">''Aeneid'', book vii, lines 706, 707.</ref>

The [[Nomen gentilicium|nomen]] ''Claudius'', originally ''Clausus'', is usually said to be derived from the Latin adjective ''claudus'', meaning "lame".  As a [[cognomen]], ''Claudus'' is occasionally found in other gentes.  However, since there is no tradition that any of the early Claudii were lame, the nomen might refer to some ancestor of Attius Clausus.  It could also have been metaphorical, or ironic, and the possibility remains that this derivation is erroneous.  The change from ''Clausus'' to ''Claudius'', and its common by-form, ''[[Clodius]]'', involves the alternation of "o" and "au", which seems to have been common in words of Sabine origin.  The alternation of "s" and "d" occurs in words borrowed from Greek: Latin ''rosa'' from Greek ''rhodon''; but in this instance ''clausus'' or ''*closus'' is a Sabine word becoming ''clod-'' in Latin.  The name could have come from Greek settlers in Latium, but there is no evidence in favor of this hypothesis.<ref>''Dictionnaire étymologique latin'', p. 44.</ref><ref>''Dictionnaire étymologique de la langue latine'', p. 126.</ref>

==Praenomina==
The early Claudii favored the [[praenomina]] ''[[Appius (praenomen)|Appius]], [[Gaius (praenomen)|Gaius]]'', and ''[[Publius (praenomen)|Publius]]''. These names were used by the patrician Claudii throughout their history. ''[[Tiberius (praenomen)|Tiberius]]'' was used by the family of the Claudii Nerones, while ''[[Marcus (praenomen)|Marcus]]'', although used occasionally by the earliest patrician Claudii, was favored by the plebeian branches of the family.<ref name="DGRBM Claudius">''Dictionary of Greek and Roman Biography and Mythology'', pp. 765–775 ("[[s:Dictionary of Greek and Roman Biography and Mythology/Claudius|Claudius]]").</ref> According to Suetonius, the gens avoided the praenomen ''[[Lucius (praenomen)|Lucius]]'' because two early members with this name had brought dishonor upon the family, one having been convicted of highway robbery, and the other of murder.<ref name="DGRBM Claudia Gens"/><ref name="Suetonius Tiberius 1"/> However, the name was used by at least one branch of the Claudii in the final century of the Republic, including one who, as ''Rex Sacrorum'', was certainly patrician. To these names, the plebeian Claudii added ''[[Quintus (praenomen)|Quintus]]'' and ''[[Sextus (praenomen)|Sextus]]'', though [[Elizabeth Rawson]] has argued that ''Quintus'' was acceptable among the [[#Claudii Pulchri|Pulchri]] as well.<ref>{{Cite book |title=Acta Instituti Romani Regni Sueciae Series in 40 |publisher=C. W. K. Gleerup |pages=10–11}}</ref>

The praenomen ''Appius'' is often said to have been unique to the Claudii, and nothing more than a Latinization of the Sabine ''Attius''. But in fact there are other figures in Roman history named "Appius", and in later times the name was used by plebeian families such as the [[Junia gens|Junii]] and the [[Annia gens|Annii]]. Thus, it seems more accurate to say that the Claudii were the only patrician family at Rome known to have used ''Appius''. As for its Sabine equivalent, ''Attius'' has been the subject of much discussion by philologists. The form ''Attus'' is mentioned by [[Valerius Maximus]], who connected it with the bucolic Greek name Atys. Braasch translated it as ''Väterchen'', "little father," and connected it with a series of childhood parental names: "atta, tata, acca," and the like, becoming such names as ''Tatius'' (also Sabine) and ''[[Atilia gens|Atilius]]''.<ref>Braasch, pp. 7-8.</ref>

During the late Republic and early Empire, the Claudii Nerones, who gave rise to the Imperial family, adopted the praenomen ''[[Decimus (praenomen)|Decimus]]'', seldom used by any patrician family. Subsequently they began to exchange traditional praenomina for names that first entered the family as cognomina, such as ''Nero'', ''Drusus'', and ''Germanicus''.

==Branches and cognomina==
The patrician Claudii bore various surnames, including ''Caecus'', ''Caudex'', ''Centho'', ''Crassus'', ''Nero'', ''Pulcher'', ''Regillensis'', and ''Sabinus''.  The latter two, though applicable to all of the gens, were seldom used when there was a more definite cognomen.  A few of the patrician Claudii are mentioned without any surname.  The surnames of the plebeian Claudii were ''Asellus'', ''Canina'', ''Centumalus'', ''Cicero'', ''Flamen'', ''Glaber'', and ''Marcellus''.<ref name="DGRBM Claudia Gens"/>

The earliest Claudii bore the surname ''Sabinus'', a common surname usually referring to a Sabine, or someone of Sabine descent, which according to all tradition, the Claudii were.{{efn-lr|Presumably, the Claudii were proud of their Sabine heritage, and used this surname to assert their ethnic identity.<ref>Farney, p. 88.</ref>}}  This cognomen was first adopted by Appius Claudius, the founder of the gens, and was retained by his descendants, until it was replaced by ''Crassus''.<ref name="DGRBM Claudia Gens"/>

''Regillensis'' or ''Inregillensis'', a surname of the earliest Claudii, is said to be derived from the town of [[Regillum]], a Sabine settlement, where Appius Claudius lived with his family and retainers before coming to Rome.  Its exact location is unknown, but it must have been in the vicinity of Lake Regillus, where one of the most important battles in the early history of the Roman Republic was fought.  The same cognomen was borne by a family of the [[Postumia gens|Postumii]], although in this instance the surname is supposed to have been derived from the [[Battle of Lake Regillus]], in which the victorious Roman general was the dictator [[Aulus Postumius Albus Regillensis|Aulus Postumius Albus]].<ref name="Suetonius Tiberius 1"/><ref>Livy, xxx. 45.</ref><ref>Niebuhr, ''History of Rome'', vol. i, p. 556.</ref>

''Crassus'', sometimes given as the diminutive ''Crassinus'', was a common surname usually translated as "thick, solid," or "dull".<ref>''Cassell's Latin and English Dictionary'', "Crassus".</ref>  This cognomen succeeded that of ''Sabinus'' as the surname of the main family of the Claudia gens.  It was borne by members of the family from the fifth to the third century BC.  The other main families of the patrician Claudii were descended from [[Appius Claudius Caecus]], the last recorded member of the Claudii Crassi, who gave a different cognomen to each of his four sons: ''Russus'' (or ''Rufus''), ''Pulcher, Cento'' or ''Centho'', and ''Nero''.<ref name="DGRBM Claudius"/>

''Pulcher'', the surname of the next major branch of the Claudia gens, means ''beautiful'', although it may be that the cognomen was given ironically.<ref>''Cassell's Latin and English Dictionary'', "Pulcher".</ref>  The Claudii Pulchri were an extensive family, which supplied the Republic with several consuls, and survived into imperial times.<ref name="DGRBM Claudius"/>[[File:Claudius Ny Carlsberg02.jpg|thumb|[[Claudius]], fourth Roman emperor]]

The other main branch of the patrician Claudii bore the surname ''Nero'', originally a Sabine praenomen described as meaning, ''fortis ac strenuus'', which roughly translated is "strong and sturdy."  It may be the same as the Umbrian praenomen ''Nerius''.  This family was distinguished throughout the latter Republic, and gave rise to several of the early emperors, including [[Tiberius]], [[Claudius]], and [[Nero]].  An oddity of the names by which these emperors are known today is that several of their ancestors bore the name ''Tiberius Claudius Nero''; of three emperors belonging to the same family, one is known by a praenomen, one by a nomen, and one by a cognomen.<ref name="Suetonius Tiberius 1"/>  Some members of the imperial family adopted the fashion of wearing their hair short at the sides and front but long in the back, over the nape of the neck.  Describing the appearance of Tiberius, [[Suetonius]] calls it a family trait.  This style visible on some busts of Tiberius and [[Caligula]], his grandnephew and successor.<ref>Suetonius, "The Life of Tiberius", 68.</ref><ref>{{cite web|url=https://www.collezionegalleriaborghese.it/en/opere/portrait-of-caligula|title=Portrait of Caligua|access-date = 16 August 2024|website = Galleria Borghese Museum}}</ref>

The most illustrious family of the plebeian Claudii bore the surname ''Marcellus'', which is a diminutive of the praenomen ''Marcus''.  They gained everlasting fame from the exploits of [[Marcus Claudius Marcellus]], one of Rome's finest generals, and a towering figure of the [[Second Punic War]], who was five times consul, and won the ''[[spolia opima]]'', defeating and killing the [[Gauls|Gallic]] king, [[Viridomarus]], in single combat.<ref>''Dictionary of Greek and Roman Biography and Mythology'', vol. II, p. 927 ("[[s:Dictionary of Greek and Roman Biography and Mythology/Marcellus|Marcellus]]", no. 2).</ref>

Most of those who used the spelling ''Clodius'' were descended from plebeian members of the gens, but one family by this name was a cadet branch of the patrician Claudii Pulchri, which voluntarily went over to the plebeians, and used the spelling ''Clodius'' to differentiate themselves from their patrician relatives.<ref>''Dictionary of Greek and Roman Biography and Mythology'', vol. I, p. 771 ("[[s:Dictionary of Greek and Roman Biography and Mythology/Claudius|Claudius]]", no. 40).</ref>

''Caecus'', the surname of one of the Claudii Crassi, refers to the condition of his blindness, which is well-attested, although it appears that he did not become blind until his old age. Caecus' initial cognomen was Crassus.<ref>Frontinus, ''De aquaeductu'', i. 5, who only gives his original cognomen, "Crassus".</ref><ref>Humm, ''Appius Claudius Caecus'', p. 35.</ref> According to one legend, he was struck blind by the gods during his [[Roman censor|censorship]], after inducing the ancient family of the [[Potitia gens|Potitii]] to teach the sacred rites of [[Hercules]] to the public slaves.  The Potitii themselves were said to have perished as a result of this sacrilege.  However, Claudius was relatively young at the time of his censorship in 312 BC, and was elected consul sixteen years later, in 296.<ref>Livy, ix. 29.</ref>

Caecus' brother, who shared the same praenomen, was distinguished by the cognomen ''Caudex'', literally meaning a "treetrunk", although metaphorically it was an insult, meaning a "dolt."  According to [[Seneca the Younger|Seneca]], he obtained the surname from his attention to naval affairs.<ref>Seneca the Younger, ''De Brevitate Vitae'', 13.</ref>
