Ridda Wars 632

The Ridda wars (Arabic: ???? ?????), also known as the Wars of Apostasy, were a set of military campaigns against the rebellion of several Arabic tribes against the Caliph Abu Bakr during 632 and 633 AD, following the death of Muhammad. The revolts, in Islamic historiography later interpreted as religious, were in reality mainly political. However, these revolts also had a religious aspect: Medina had become the centre of a social and political system, of which religion was an integral part; consequently it was inevitable that any reaction against this system would have a religious aspect.
