Impact of seventh-century Islam
The seventh century saw the rise of Mohammedanism when Mohammed made Mecca the center of his new cult. Believing that a new religious era had been established in 622, the year Mohammed fled for his life from Mecca, his followers carried on a militant crusade from country to country throughout the Near East. Their steady progress against all opposition resulted in the loss to the empire of Syria, Palestine, Egypt, North Africa, and Spain.
