Henry II of Navarre was born in 1503 in Spain. In 1512, he together with his parents John III and Catherine I of Navarre, escaped to the northern part of their kingdom, when Fedrinand II of Aragon conquered the spanish part of the Kingdom of Navarre. After several re-conquest attempts made by John and Catherine, the two died in 1516 and 1517 respectively. Henry was only 14, but Francis I proved an ally and warned Queen Joanna I not to attack the rest of Navarre. Trying several reconquests himself, the resigned Treaty of London in 1523 stopped the attempts. Trying to find a bride, John III of Portugal offered him his niece Catherine and Henry accepted. Henry was fluent in french and spanish and had some reformational sympathies for the Lutheran church.
