Marcus Aurelius Cotta (consul 74 BC)

Marcus Aurelius Cotta was a Roman politician and general who was consul in 74 BC and was one of the early Roman commanders who fought in the Third Mithridatic War.

Cotta, hailing from a distinguished plebeian family, was the son of Lucius Aurelius Cotta who was consul in 119 BC, while his older brother Gaius Aurelius Cotta preceded him as consul in 75 BC. His younger brother Lucius Aurelius Cotta was consul in 65 BC. Aurelia Cotta, the mother of Julius Caesar, was his halfsister.

Climbing the cursus honorum, it is assumed that he held the post of praetor in 77 BC. Elected consul in 74 BC alongside Lucius Licinius Lucullus, he was soon concerned with the escalating situation in the east brought about by the acquisition of the new province of Bithynia and the subsequent renewal of conflict with King Mithridates VI of Pontus who had invaded Bithynia. Having received Bithynia as his proconsular command he received command of a fleet to protect his province and was dispatched to the east towards the end of his period as consul.

The original plan was that Cotta should tie down Mithridates' fleet, while Lucullus attacked by land. Cotta was therefore ordered to station his fleet at Chalcedon, while Lucullus marched through Phrygia with the intention of invading Pontus. Lucullus had not advanced far when news came through that Mithridates had made a rapid march westward, attacked Cotta, and forced him to flee behind the walls of Chalcedon. Sixty-four Roman ships had been captured or burnt, and Cotta had lost three thousand men. There Cotta was forced to remain until Lucullus could to come to his rescue.
