Lithuanians and Poles controlled vast estates in Ukraine, and were a law unto themselves. Judicial rulings from Kraków were routinely flouted, while peasants were heavily taxed and practically tied to the land as serfs. Occasionally the landowners battled each other using armies of Ukrainian peasants. The Poles and Lithuanians were Roman Catholics and tried with some success to convert the Orthodox lesser nobility. In 1596, they set up the "Greek-Catholic" or Uniate Church; it dominates western Ukraine to this day. Religious differentiation left the Ukrainian Orthodox peasants leaderless, as they were reluctant to follow the Ukrainian nobles.
