Which Pope made an agreement in 1513 with a king called the Catholic?
Treaty of Mechlin (1513) The Treaty of Mechlin (1513) (also known as the "Treaty of Malines") was an agreement between Henry VIII, Maximilian I, Holy Roman Emperor, Ferdinand II of Aragon and Pope Leo X to form an alliance against France. The treaty was the first of a series of treaties (the others being the Treaties of London of 1516 and 1518 and the Treaty of Cambrai of 1517) which attempted to unite the main European powers by building a holy league in order to establish a "respublica christiana".
Treaty of Christmemel The Treaty of Christmemel (Lithuanian: "Skirsnemunės sutartis" ) was a treaty signed on 19 June 1431 between Paul von Rusdorf, Grand Master the Teutonic Knights, and Švitrigaila, Grand Duke of Lithuania. Švitrigaila was preparing for a war with Poland to defend his claim to the Lithuanian throne and sought allies. The treaty established an anti-Polish alliance and prompted the Knights to invade the Kingdom of Poland, starting the Polish–Teutonic War (1431–35). Lithuania also surrendered Palanga and three miles of the coastline on the Baltic Sea, thus modifying the Treaty of Melno of 1422.
