The Umayyad Dynasty, which ruled from 661 to 750 CE, expanded its territory significantly, conquering vast regions including the Iberian Peninsula (modern-day Spain and Portugal), North Africa, and parts of the Byzantine Empire. They also made significant incursions into Central Asia and the Indian subcontinent, notably capturing areas like Sindh. Their conquests facilitated the spread of Islam and Arab culture across these regions. The Umayyads are known for establishing one of the largest empires in history during their rule.
