After the Bohemian loss to Austria at the Battle of White Mountain of 1620, many Czechs adhering to the Moravian Church fled subsequent Austrian Catholic persecution to Poland. The main center of Czechs in Poland became Leszno. Notable Czech refugee in Poland was philosopher John Amos Comenius. A notable remnant of the Czech Protestants in Poland are the files and library of the Unity of the Brethren from Leszno, now held at the State Archive and Raczyà Âski Library in Poznaà  and the Kórnik Library in Kórnik, and listed on the UNESCO Memory of the World Register.
In the 19th century, Czechs also settled in Zelów and its environs and in Volhynia. Czechs of Kwasià Âów in Volhynia founded a local branch of the Sokol movement in 1911, which formed part of the Polish SokÃ³à  movement. Within interwar Poland, the main centers of Czechs were Zelów and Kwasià Âów in the Woà Âyà  Voivodeship (1.5%). After the war many Czechs of Volhynia were expelled by the Soviet Union, and forcibly resettled in Czechoslovakia.
