Excerpts from Books and Wikipedia
"Bohemia was a small country; for over a decade, the regular business of trading, farming, and living had been completely disrupted by war; over a hundred thousand men had died in the fighting, and waves of plague had swept across the country again and again. Unfortunately, the Hussite movement had now matured enough to sub-divide into sects, and most radical of the Hussites refused to agree to any compromise. . . . At Lipany, on May 30, 1434, a pitched battle between the extremists and the moderate-Catholic alliance ended with the defeat of the fanatics and an eventual compromise, sworn out in 1436. The Compactata, the Compacts of Basel, recognized the Hussites as part of the Catholic Church although different in practice and belief: the first time that western Christianity had recognized the existence of a distinct sect as inside Christianity, yet outside pure Catholic doctrine. . . . The Compacts of Basel had managed to bring Bohemia back within the empire, but the kingdom's submission was brief." [Bauer: Renaissance World, p. 649]
