Achaea[1][2] or Achaia[3][4][5] (Greek: Ἀχαΐα Achaïa), was a province of the Roman Empire, consisting of the Peloponnese, eastern Central Greece, and parts of Thessaly. In the north, it bordered on the provinces of Epirus vetus and Macedonia. The region was annexed by the Roman Republic in 146 BC following the sack of Corinth by the Roman general Lucius Mummius, who was awarded the cognomen "Achaicus" ("conqueror of Achaea").
