Tiberius
second Roman Emperor from 14 to 37 AD
Tiberius Julius Caesar Augustus ( ty-BEER-ee-əs; 16 November 42 BC – 16 March AD 37) was the second Roman emperor from AD 14 until his death, reigning as the second ruler of the Julio-Claudian dynasty. He succeeded his stepfather Augustus, the first Roman emperor. Tiberius was born in Rome in 42 BC to politician Tiberius Claudius Nero and his wife, Livia Drusilla. In 38 BC, Livia divorced Nero and married Augustus. Following the untimely deaths of Augustus's two grandsons and adopted heirs, Gaius and Lucius Caesar, Tiberius was designated Augustus's successor. Prior to this, Tiberius had proved himself an able diplomat and one of the most successful Roman generals. His conquests of Pannonia, Dalmatia, Raetia, and (temporarily) parts of Germania laid the foundations for the empire's northern frontier.
Early in his career, Tiberius was happily married to Vipsania, daughter of Augustus's boyhood friend, distinguished general and intended heir, Marcus Vipsanius Agrippa. They had a son, Drusus Julius Caesar. After Agrippa died, Augustus had Tiberius divorce Vipsania and marry his step-sister Julia, Agrippa's widow and Augustus' daughter; Tiberius relented.

Why this record matters
The phrase “second Roman Emperor from 14 to 37 AD” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q1407. VIAF identifies the subject as 89600176. The Library of Congress control number is n50049381. 4 of 10 selected statements include explicit references; 3 carry qualifiers and 1 use preferred rank.
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.
