What happened 30 AD

Octavian's forces invaded Egypt in 30 BC. Although Antony and Cleopatra offered military resistance, Octavian defeated their forces, leading to Antony's suicide. When it became clear that Octavian planned to have Cleopatra brought to Rome as a prisoner for his triumphal procession, she also committed suicide, the cause of death reportedly by use of poison. The popular belief is that she was bitten by an asp.

Cleopatra, though long desiring to preserve her kingdom, decided in her last moments to send Caesarion away to Upper Egypt perhaps with plans to flee to Nubia, Ethiopia, or India. Caesarion, now Ptolemy XV, reigned for a mere eighteen days until he has executed on the orders of Octavian on 29 August 30 BC.

Cleopatra's death on 10 or 12 August 30 BC.

Ptolemaic Kingdom continued in Egypt until 30 BC when it too was conquered by the Romans.
