Why did rome invade Cyprus?

The main reason for the Roman invasion of Cyprus in 58 BC was to punish the Cypriot king, Ptolemy XII Auletes, for his support of the Roman Republic's enemy, Pompey the Great. Ptolemy XII had previously been an ally of Rome and had been recognized as the legitimate king of Cyprus by the Roman Senate. However, he had sided with Pompey during the Roman civil war, and after Pompey's defeat at the Battle of Pharsalus in 48 BC, he had fled to Cyprus.

Rome saw Ptolemy XII's support for Pompey as a betrayal and considered it a threat to their control over the eastern Mediterranean. The island of Cyprus was strategically located and was a valuable source of copper, timber, and other resources. By invading Cyprus, Rome aimed to punish Ptolemy XII and secure their control over the region.

Ptolemy XII was aware of the Roman invasion force approaching Cyprus and realized he could not resist it. Therefore, he decided to commit suicide rather than face the consequences of his actions. After his death, Rome annexed Cyprus and turned it into a Roman province.
