What happened in the 3rd triumvirate?

The Third Triumvirate, formed in 43 BCE, was a political alliance between Octavian, Mark Antony, and Marcus Lepidus, established to consolidate power after the assassination of Julius Caesar. They aimed to defeat Caesar's assassins and restore order to Rome, leading to the formation of a proscriptions list targeting their enemies. However, internal conflicts arose, particularly between Octavian and Antony, eventually leading to a power struggle that culminated in the Battle of Actium in 31 BCE, where Octavian emerged victorious, paving the way for his rise as the first Roman emperor.
