About this source

What it is

This is a printed genealogical chart from Sir William Smith's 'A Dictionary of Greek and Roman Biography and Mythology', published in 1867. It traces the family of Augustus, starting with his father C. Octavius and mother Atia, and following descendants through Livia, Tiberius, Agrippina, Caligula and other members of the Julio-Claudian dynasty.

Why it matters

This chart helps show how Augustus built a dynasty through marriage alliances and adoptions, a strategy that shaped who would rule Rome after him. It reveals the complicated family politics behind the succession of later emperors like Tiberius and Caligula.

Look closer

  • Why do you think so many marriages and adoptions appear in this family tree?
  • What does the chart suggest about how Roman emperors tried to secure their successors?
  • How might a reference book from 1867 differ from how Romans themselves understood their own family?
