Alexander Farnese (Italian: Alessandro Farnese, Spanish: Alejandro Farnesio; 27 August 1545 – 3 December 1592) was an Italian noble and condottiero who was Duke of Parma, Piacenza and Castro from 1586 to 1592, as well as Governor of the Spanish Netherlands from 1578 to 1592.
He is best known for his successful campaign 1578-1592 against the Dutch Revolt, in which he captured the main cities in the south (now Belgium) and returned them to the control of Catholic Spain.
During the French Wars of Religion he relieved Paris for the Catholics.
His talents as a field commander, strategist and organizer earned him the regard of his contemporaries and military historians as the first captain of his age.
