He became the Admiral of the Genoese Fleet in 1556, and commanded the combined Christian fleet of the Holy League at the Battle of Djerba in 1560, which was won by the Ottoman Turks under the command of Piyale Pasha. He also participated in the Battle of Lepanto (1571), commanding the right wing, which was won by the Christian forces and signaled the first ever defeat of the Ottoman Turks at sea. Doria also led an expedition against the Barbary states in 1601.
