A Kendite prince called Yazid bin Kabshat rebelled against Abraha and his Arab Christian allies. A truce was reached once the Great Dam of Marib had suffered a breach. Abraha died around 570CE; Sources regarding his death are available from the qur'an and hadith. The Sasanid Empire annexed Aden around 570 CE. Under their rule, most of Yemen enjoyed great autonomy except for Aden and Sana'a. This era marked the collapse of ancient South Arabian civilization since the greater part of the country was under several independent clans until the arrival of Islam in 630 CE.
