Wars have been waged over millions of square miles, significantly larger than the British Empire at its peak. Historically, Islamic conquests stretched from southern France to the Philippines, from Austria to Nigeria, and from central Asia to New Guinea. The Muslim goal was to have a central government, first at Damascus, and then at Baghdad, later at Cairo, Istanbul, and other imperial centres. The local governors, judges, and other rulers were appointed by the central imperial authorities for far off colonies. Islamic law was introduced as the senior law, whether or not wanted by the local people. Arabic was introduced as the rulers’ language, while the local languages frequently disappeared. Then, two classes of residents were established. The native residents paid a tax that their rulers did not have to pay. In each case, these laws allowed the local conquered people less freedom than was given to Muslims.
