institutions were established. Those involved in social welfare included the accelerated development of schools and community centres, and a modern, fully equipped hospital in Nairobi. Among the economic development institutions established in East Africa were companies such as the Diamond Jubilee Investment Trust (now Diamond Trust of Kenya) and the Jubilee Insurance Company, which are quoted on the Nairobi Stock Exchange and have become major players in national development. Sir Sultan Mahomed Shah also introduced organizational reforms that gave Ismāʿīlī communities the means to structure and regulate their own affairs. These were built on the Muslim tradition of a communitarian ethic on the one hand, and responsible individual conscience with freedom to negotiate one's own moral commitment and destiny on the other. In 1905 he ordained the first Ismā'īlī Constitution for the social governance of the community in East Africa.

The constitution also set out rules in such matters as marriage, divorce and inheritance, guidelines for mutual cooperation and support among Ismā'īlīs, and their interface with other communities. Similar constitutions were promulgated in India, and all were periodically revised to address emerging needs and circumstances in diverse settings. In 1905, the Aga Khan was involved in the Haji Bibi case, where he was questioned about the origin of his followers. In his response, in addition to enumerating his followers in Iran, Russia, Afghanistan, Central Asia, Syria and other places, he also noted that “In Hindustan and Africa there are many Guptis who believe in me…I consider them Shi’i Imami Ismailis; by caste they are Hindus”. Following the Second World War, far-reaching social, economic and political changes profoundly affected a number of areas where Ismāʿīlīs resided. In 1947, British rule in the Indian Subcontinent was replaced by the sovereign, independent nations of India, Pakistan and later Bangladesh, resulting in the migration of millions people and significant loss of life and property. In the Middle East, the Suez crisis of 1956 as well as the preceding crisis in Iran, demonstrated the sharp upsurge of nationalism, which was as assertive of the region's social and economic aspirations as of its political independence. Africa was also set on its course to decolonisation, swept by what Harold Macmillan, the then British prime minister, termed the "wind of change". By the early 1960s, most of
