Daughter of two rival houses
Antonia Minor was the younger daughter of Mark Antony and Octavia Minor. Her marriage to Drusus the Elder joined Antony’s descendants to the Claudian branch. Their surviving children were Germanicus, Livilla, and Claudius.
Widow and guardian of a dynasty
After Drusus died in 9 BCE, Antonia did not remarry. She became a respected senior figure who helped raise descendants and royal dependants, including children of Germanicus and eastern client princes. Her household therefore stood at the intersection of Roman and allied dynasties.
Claudius and Livilla
Suetonius preserves cutting remarks attributed to Antonia about Claudius’s disabilities and intellect; these belong to a hostile literary tradition and do not give access to their entire relationship. Later accounts also credit Antonia with revealing the conspiracy of Sejanus and Livilla in 31 CE, although the evidence for her precise role varies.
Final honours
Caligula granted Antonia exceptional honours at his accession. She died weeks later in 37 CE; stories that Caligula drove her to suicide or caused her death are ancient allegations, not established conclusions. Claudius later awarded her the title Augusta and public honours.
