Amṣar (Arabic: أمصار), refer to civilised cities and large areas in which houses, markets, schools and other public facilities are located.[1] The plural form also sometimes referred to 'garrison towns' or structures that were established by Muslim warriors in conquered lands, in the first centuries of Islam.[2] The first were created under Caliph Omar during his reign from 634 to 644 AD.[3] Many of these garrisons attracted civilians and became towns.
