Far East Farther east still, the Indonesians finally gained their independence from the Dutch and the Malays theirs from Britain. At first Singapore was part of Malaysia but it separated in 1963 to become an independent state. Small colonies still persisted in the area and continued to seek their independence, the kingdom of Brunei becoming independent as recently as 1984. Africa In Africa also major countries with large or majority Muslim populations such as Nigeria, Senegal and Tanzania began to gain their independence in the 1950's and 1960's with the result that by the end of the decade of the 60's most parts of the Islamic world were formed into independent national states. There were, however, exceptions. The Muslim states in the Soviet Union failed to gain their autonomy or independence. The same holds true for Sinkiang (called Eastem Turkestan by Muslim geographers) while in Eritrea and the southern Philippines Muslim independence movements still continue. National States While the world of Islam has entered into the modern world in the form of national states, continuous attempts are made to create closer cooperation within the Islamic world as a whole and to bring about greater unity. This is seen not only in the meetings of the Muslim heads of state and the establishment of the OIC (Organization of Islamic Countries) with its own secretariat, but also in the creation of institutions dealing with the whole of the Islamic world. Among the most important of these is the Muslim World League (Rabitat al-alam al-Islami ) with its headquarters in Makkah. Saudi Arabia has in fact played a pivotal role in the creation and maintenance of such organizations.
