RAZZIA (an adaptation of the Algerian Arabic ghaziah, from ghasw, to make war), a foray or raid made by African Moslems. As used by the Arabs, the word denotes a military expedition against rebels or infidels, and razzias were made largely for punishment of hostile tribes or for the capture of slaves. English writers in the early years of the 19th century used the form ghrazzie, and Dixon Denham in his Travels (1826) styles the raiding force itself the ghrazzie. The modern English form is copied from the French, while the Portuguese variant is gazia, gaziva.
