Source-derived summary

Tiberius Claudius Caesar Augustus Germanicus ( KLAW-dee-əs; Classical Latin: [tɪˈbɛri.ʊs ˈkɫau̯di.ʊs ˈkae̯sar au̯ˈɡʊstʊs ɡɛrˈmaːnɪkʊs]; 1 August 10 BC – 13 October AD 54), or simply Claudius, was a Roman emperor, ruling from AD 41 until his death in AD 54. The fourth ruler of the Julio-Claudian dynasty, Claudius was born to Drusus the Elder, the brother of Emperor Tiberius, and Antonia Minor at Lugdunum in Roman Gaul, where his father was stationed as a military legate. He was the first Roman emperor to be born outside Italy.

As he had a limp, a stammer, and a tremor due to an illness he suffered when young, Claudius was ostracized by his family and was excluded from public office until his consulship (which was shared with his nephew, Caligula, in AD 37). His infirmity probably saved him from the fate of many other nobles during the purges throughout the reigns of Tiberius and Caligula, as potential enemies did not see him as a serious threat. His survival led to him being declared emperor by the Praetorian Guard after Caligula's assassination, at which point he was the last adult male of his family.

Despite his lack of experience, Claudius was an able and efficient administrator. He expanded the imperial bureaucracy to include freedmen, and helped restore the empire's finances after the excesses of Caligula's reign. He was also an ambitious builder, constructing new roads, aqueducts, and canals across the Empire. During his reign, the Empire started its successful conquest of Britain.

Editorial summary

This brief starts where responsible research should: with the source description of “Claudius” as fourth Roman emperor (41–54). Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 248-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date -0010-08-01. The account is most persuasive where Claudius, fourth and Roman can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as fourth Roman emperor (41–54). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q1411. VIAF identifies the subject as 87172361. The Library of Congress control number is n50041157. 2 of 7 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
