The Rashidun Caliphate was the first caliphate in Islamic history, established after the death of the Prophet Muhammad in 632 CE. It lasted until 661 CE and was led by four caliphs: Abu Bakr, Umar, Uthman, and Ali. This period is known for its rapid expansion of Islamic territory and the establishment of administrative and military structures. During the Rashidun Caliphate, the Islamic state expanded significantly, conquering regions such as Syria, Egypt, and parts of Persia. The caliphs focused on spreading Islam and implementing its teachings, which laid the foundation for future Islamic governance and culture.
