بنو قسي موطنهم و بداية ظهورهم حتى سنة 180ه 796م

الملخص EN

Andalusia families had a great role in the Islamic history in Andalus, especially those families which inhabited the upper defile for it is the region to the borders with the Christian kingdoms.

All along this defile many events happened that positively and negatively impacted the Islamic state.

Therefore, to know these borders we can simply tell the size of the challenges in the region and the role that the families played in stabilizing the region or violating discipline and order there.

This is what urged us to choose the Qassi family to be the core of the study.

This family hadn't received historians and researchers' attentions.

Thus, we couldn't find any study which shed light on this family.
