The Tiwanaku civilization was a highly organized society, with a complex social and political hierarchy. The capital city of Tiwanaku was a center of religion, commerce, and political power, and it is believed that the rulers of Tiwanaku controlled a large area of the surrounding region. The civilization was also highly religious, with a complex pantheon of deities and a sophisticated system of religious ceremonies and rituals.

The decline of the Tiwanaku civilization is still not fully understood, but it is believed to have been the result of a combination of factors, including environmental degradation, social unrest, and invasion by neighboring cultures. Despite its decline, the Tiwanaku civilization had a lasting impact on the region, and its legacy can still be seen in the art, architecture, and culture of modern-day Bolivia and Peru.
