Slavery in Russia
While slavery has not been widespread on the territory of what is now Russia since the introduction of Christianity in the 10th century, serfdom in Russia, which was in many ways similar to landless peasantry in Catholic Europe, only ended in February 19th, 1861 when Emperor Alexander II ordered the emancipation of the serfs in 1861. The emancipation of state-owned serfs occurred in 1866.
