Answer
In 272 BC, Pyrrhus, the king of Epirus, invaded the Peloponnese. His invasion was part of a larger conflict known as the Pyrrhic War, which pitted Pyrrhus against the Roman Republic and its allies. Pyrrhus's invasion was initially successful, and he won several battles against the Romans. However, he was eventually defeated by the Romans at the Battle of Beneventum in 275 BC.
