Sassanian Empire

The Sassanian Empire, also known as the Sassanid Empire, existed from 224 to 651 CE in what is now Iran and parts of neighboring countries. It was the last pre-Islamic Persian empire, known for its achievements in art, science, and architecture, as well as for its strong centralized government and Zoroastrian religion. The Sassanian period saw significant cultural and economic development, along with conflicts with the Roman Empire and later the Byzantine Empire. The empire fell to the Arab Muslim conquests, which led to the widespread adoption of Islam in the region.
