On this date, April 22, 1418, the Council of Constance formally concluded. This Council, lasted nearly four years. At the time, there were three rival popes; John XXIII, and Benedict XIII. That created many problems as they all wanted to be in charge. The council also condemned and executed the two Bohemian reformers, John Huss in 1415 and his close friend and disciple, Jerome of Prague, in 1417.
