Tiberius. Tiberius was the second Roman emperor, reigning from AD 14 to 37. He succeeded his stepfather, Augustus.

Tiberius would later marry Augustus' daughter, Julia the Elder, and even later be adopted by Augustus. Through the adoption, he officially became a Julian, assuming the name Tiberius Julius Caesar.
The emperors after Tiberius would continue this blended dynasty of both families for the following thirty years; historians have named it the Julio-Claudian dynasty. His relationship to the other emperors of this dynasty was as follows: He was the stepson of Augustus, grand-uncle of Caligula, paternal uncle of Claudius, and great-grand uncle of Nero.
