In 1419 the Hussite Wars began, and in their course the Hussite movement splintered into several groups. The moderate group, called Utraquists [Lat. sub utraque specie = in both kinds] or Calixtines [Lat., = chalice], consisted chiefly of the lesser nobility and the bourgeoisie. The Univ. of Prague was their center and Master Jan Rokycana their principal leader. Except for the demands made in the Four Articles, they agreed substantially with the Roman Catholic Church.
The more radical Hussites, the Taborites, named after their religious center and stronghold at Tabor, went further than the Utraquists in accepting the doctrines of John Wyclif. Consisting largely of peasants, this group expressed the messianic hopes of the oppressed. They regarded the Four Articles as minimal concessions. Their real goal was the total abolition of the feudal system and the establishment of a classless society without private property. From among their number came such leaders as John Zizka and Procopius the Great. Puritanical and iconoclastic, the Taborites reduced the sacraments to communion and baptism, denied the Real Presence, and abolished the veneration of saints and holy images.
The Hussite Wars necessitated a temporary alliance between the two groups. However, when the Utraquists were reconciled (1436) with the church through the agreement known as the Compactata, the Taborites refused to acquiesce. Of the demands of the original Four Articles, the Catholic Church conceded only on communion in both kinds. The obstinacy of the Taborites led to the alliance between the Utraquists and the Catholics and to the military defeat of the Taborites at Lipany (1534). After this, Taborite influence vanished from Bohemia. The Bohemian and Moravian Brethren are, however, probably descended from this group (see Moravian Church).
