Following the Protestant Reformation, promoted by local reformer Martin Bucer, the principle of cuius regio, eius religio led to a certain amount of religious diversity in the highlands of northern Alsace. Landowners, who as "local lords" had the right to decide which religion was allowed on their land, were eager to entice populations from the more attractive lowlands to settle and develop their property. Many accepted without discrimination Catholics, Lutherans, Calvinists, Jews and Anabaptists. Multiconfessional villages appeared, particularly in the region of Alsace bossue. Alsace became one of the French regions boasting a thriving Jewish community, and the only region with a noticeable Anabaptist population. The schism of the Amish under the lead of Jacob Amman from the Mennonites occurred in 1693 in Sainte-Marie-aux-Mines. The strongly Catholic Louis XIV tried in vain to drive them from Alsace. When Napoleon imposed military conscription without religious exception, most emigrated to the American continent.
