 Corsair activity based in Algiers did not entirely cease until France conquered the state in 1830.The Crimeans frequently mounted raids into the Danubian principalities, Poland-Lithuania, and Muscovy to enslave people whom they could capture; for each captive, the khan received a fixed share (savğa) of 10% or 20%.These campaigns by Crimean forces were either "sefers" ("sojourns" – officially declared military operations led by the khans themselves), or "çapuls" ("despoiling" – raids undertaken by groups of noblemen, sometimes illegally because they contravened treaties concluded by the khans with neighbouring rulers).
