Anṣâr (Arabic: الأنصار‎‎, meaning aiders, or patrons) refer to a class of warriors who are renowned for their arsenal of weapons and for their speed and mobility on the battlefield. The quality of the Arabian horses quickly led to these soldiers dominating the battlefield, making ample use of their array of weaponry, which consisted of javelins, a sword, and bow and arrows. The one military unit that was present in nearly all of the Arabic expansion of the 7th to 9th centuries was the Anṣâr Warrior. These warriors participated as infantry, but most commonly rode on horseback and were famed to be the greatest horsemen/infantry of their time.
