In historical terms, the razzia roundup was used in French colonial context for Muslim raids particularly to plunder and capture slaves from Western and Central Africa, also known as rezzou when practiced by the Tuareg. (See also: Barbary slave trade) The word was adopted from ġaziya of Algerian Arabic vernacular and later became a figurative name for any act of pillage, with its verb form razzier. The Soviets used similar tactics to round up middle-class Poles in the part of Poland that they occupied following the 1939 invasion of Poland.
