Muslim history

Muslim history is concerned with the history of the Islamic faith as a religion and as a social institution. The evolution of Islam has impacted the political, economic, and military history of an enormous geography. The concept of the Islamic world is useful in observing the different periods of Islamic history; similarly useful is an understanding of the identification with a quasi-political community of believers, or ummah, on the section of Islam's practitioners down the centuries. Islamic culture encourages identification with the ummah, and this principle has influenced the behavior of a number of players in history. The history of Islam is closely tied to the political, economic, and military.
