The Hussite Crusades involved the military actions against and amongst the followers of Jan Hus in Bohemia ending ultimately with the Battle of Grotniki. Also known as the Hussite Wars, they were arguably the first European war in which hand-held gunpowder weapons such as muskets made a decisive contribution. The Taborite faction of the Hussite warriors were basically infantry, and their many defeats of larger armies with heavily armored knights helped effect the infantry revolution. In totality, the Hussite Crusades were inconclusive.
