House of Sforza
The campaign of Marignano followed years of Swiss successes, during which French fortunes in Northern Italy had suffered greatly. The Swiss had taken control of Milan (for France the gateway to Italy) after their victory at the Battle of Novara (1513), and returned to its ducal throne Massimiliano, son of Ludovico Sforza, the last duke of the House of Sforza to rule independent Milan, as their puppet.
