The legacy of colonialism is key in explaining both the diversity and the unity of different experiments with state formation in the Muslim world. Just as Islam, ethnic identity, social characteristics, and other indigenous religious and cultural factors can explain the commonalities between Muslim states—and conversely, economics, ideology, and leadership can explain divergences—colonialism too can explain the points of convergence and divergence in experiences with state formation across the Muslim world. Muslims have lived with nearly all the colonial powers. In much of Africa, Asia, and the Arab world, the British and the French ruled over vast Muslim territories. The Dutch ruled over territories that later became Indonesia, and the Germans, Spanish, Portuguese, and Russians held Muslim territories in East Africa, the Philippines, Malaya (what is now known as Malaysia), the Caucasus, and Central Asia. Israel's control of the West Bank and Gaza Strip may be seen as the last and only ongoing colonial relationship in Muslim lands. Although the defining characteristics of colonialism were at work in all of these locales, there were differences in how colonial powers approached their colonial mandates, even differences in how the same colonial powers exerted power and influence in different territories. There are thus fundamental similarities between various Muslim polities as there are particularities, which have their roots in history, and more important, with the experience of each colonial territory.
