Early Caliphate

Early Caliphate
Main articles: Caliphate, Arab Empire, and Islamic Golden Age
After Muhammad died, a series of Caliphs governed the Islamic State: Abu Bakr Siddique, Umar, Uthman and Ali. These first Caliphs are popularly known as the "Rashidun" or "rightly-guided" Caliphs in Sunni Islam. After the Rashidun, a series of Caliphates were established. Each caliphate developed its own unique laws based on the sharia. There were at times competing claims to the Sunni caliphate, and the Imams of Ismaili Shi'a Islam, descended from Ali and Muhammad through his daughter Hazrat Fatimah, set up their own caliphate which ruled the Fatimid Empire.
