Andrew II issued the Diploma Andreanum which secured the special privileges of the Transylvanian Saxons and is considered the first Autonomy law in the world. He led the Fifth Crusade to the Holy Land in 1217, setting up the largest royal army in the history of Crusades. His Golden Bull of 1222 was the first constitution in Continental Europe. The lesser nobles also began to present Andrew with grievances, a practice that evolved into the institution of the parliament (''parlamentum publicum'').
