Family and youth

Tiberius was born in Rome on 16 November 42 BC to Tiberius Claudius Nero and Livia Drusilla. Both of his biological parents belonged to the gens Claudia, an ancient patrician family that came to prominence in the early years of the republic. His mother was also a member of the Livii family, an ancient plebeian but prominent family, through the adoption into it of his maternal grandfather. Little is recorded of Tiberius's early life. In 39 BC, his mother divorced his biological father and, though again pregnant by Tiberius Nero, remarried to Octavian, later known as Augustus. In 38 BC his brother, Nero Claudius Drusus, was born. In 32 BC, Tiberius, at the age of nine, delivered the eulogy for his biological father at the rostra. In 29 BC, he rode in the triumphal chariot along with his adoptive father Octavian in celebration of the defeat of Antony and Cleopatra at Actium.
