The Khulafae Rashedeen were the first four leaders (caliphs) of the Muslim community after the death of the Prophet Muhammad (632-661 AD). They were Abu Bakr, Umar, Uthman, and Ali, who were selected through various consultative processes. They achieved expanding and administering the new Islamic empire through military conquests, establishing political and economic institutions, and promoting the Quran. However, disagreements over authority and leadership selection sowed the seeds of future divisions between Sunni and Shia Muslims.
