The two states were the greatest powers of West Asia, and the rivalry was further fueled by dogmatic differences: the Ottomans were Sunnis, while the Safavids were staunchly Shia Muslims of the Qizilbash sect, and seen as heretics by the Ottomans.
The supreme leaders of the DPRK have been Kim Il-sung, his son Kim Jong-il, and his grandson Kim Jong-un.

No one event was the actual cause of the revolution. It was, instead, a series of events that led to the war. Essentially, it all began as a disagreement over the way Great Britain treated the colonies versus the way the colonies felt they should be treated.
Americans felt they deserved all the rights of Englishmen. The British, on the other hand, felt that the colonies were created to be used in the way that best suited the crown and parliament. This conflict is embodied in one of the rallying cries of the American Revolution: No Taxation Without Representation.
