During the period between 1621 and 1754 when the British drew resources and attention away from the thirteen American colonies, which were left virtually independent to develop their own governmental policies and to pursue their own economic interests.
Between 1945 and 1960, three dozen new states in Asia and Africa achieved autonomy or outright independence from their European colonial rulers. There was no one process of decolonization. In some areas, it was peaceful, and orderly. In many others, independence was achieved only after a protracted revolution. A few newly independent countries acquired stable governments almost immediately; others were ruled by dictators or military juntas for decades, or endured long civil wars.
