<P> Despite having married Octavia, Octavian's sister, in 40 BC (Octavian had married Antony's stepdaughter Clodia Pulchra three years earlier), Antony openly lived in Alexandria with Cleopatra VII of Egypt, even siring children with her . When the Triumvirate's second term expired in 33 BC, Antony continued to use the title Triumvir; Octavian, opting to distance himself from Antony, refrained from using it . </P> <P> After Antony's defeat in Parthia, Cleopatra had come to his aid with supplies; Antony then turned his attention to Armenia, seizing its king Artavasdes and occupying the country . He minted coins to commemorate the victory, created a mimic of a Roman triumph, and read out a declaration, known as the Donations of Alexandria in which he granted territories to Cleopatra's children . </P> <P> Octavian illegally obtained Antony's will in July 32 BC and exposed it to the Roman public: it promised substantial legacies to Antony's children by Cleopatra, and left instructions for shipping his body to Alexandria for burial . Octavian's forces decisively defeated those of Antony and Cleopatra at the Battle of Actium in Greece in September 31 BC, chasing them to Egypt in 30 BC; both Antony and Cleopatra committed suicide in Alexandria, and Octavian personally took control of Egypt and Alexandria (Egyptian chronologies treat Octavian as Cleopatra's successor as Pharaoh). </P> <P> Octavian's ally Gaius Maecenas forestalled a conspiracy allegedly organised by Lepidus's son (31 BC). With the complete defeat of Antony and the marginalisation of Lepidus, Octavian, having been restyled "Augustus" in 27 BC, remained as the sole master of the Roman world, and proceeded to establish the Principate as the first Roman "emperor". </P>
