Uqba ibn Nafi
Initially the Berber States were able to defeat the Umayyad invaders at the Battle of Vescera (modern Biskra in Algeria), that was fought in 682 AD between the Berbers of King Kusaila and their Byzantine allies from the Exarchate of Africa against an Umayyad army under Uqba ibn Nafi, the founder of Kairouan.
