At the commencement of the Muslim conquest of Egypt, Egypt was part of the Byzantine Empire with its capital in Constantinople. However, it had been occupied just a decade before by the Persian Empire under Khosrau II (616 to 629 AD). Emperor Heraclius re-captured Egypt after series of brilliant campaigns against the Sassanid Persians, only to once again lose it to the Rashidun army ten years later. Before the Muslim invasion of Egypt began, the Byzantine Empire had already lost the Levant and its Arab ally, the Ghassanid Kingdom, to the Muslims. This all left the Byzantine Empire dangerously exposed and vulnerable to the invaders.^[1]
