left to be replaced by Canadian troops. On 26 April 1964, Tanganyika united with Zanzibar to form the United Republic of Tanganyika and Zanzibar. The country was renamed the United Republic of Tanzania on 29 October of that year. The name Tanzania is a blend of Tanganyika and Zanzibar and previously had no significance. Under the terms of this union, the Zanzibar Government retains considerable local autonomy. Recent history To form a sole ruling party in both parts of the union, Julius Nyerere merged TANU with the Zanzibar ruling party, the Afro-Shirazi Party (ASP) of Zanzibar to form the CCM (Chama cha Mapinduzi-CCM Revolutionary Party), on February 5, 1977. The merger was reinforced by principles enunciated in the 1982 union constitution and reaffirmed in the constitution of 1984. Nyerere believed multiple political parties, in a nation with hundreds of ethnic groups, were a threat to national unity and therefore sought ways to ensure a one party system. In a post-colonial and unstable social environment, Nyerere 'well aware of the divisiveness of ethnic chauvinism moved to excise tribalism from national politics' (Locatelli & Nugent, 2009: 252). To further his aim for national unity Nyerere established Kiswahili as the national language. Nyerere introduced African socialism, or Ujamaa, literal meaning 'family-hood'. Nyerere's government had made Ujamaa the philosophy that would guide Tanzania's national development; 'the government deliberately de-emphasized urban areas to deconcentrate and ruralize industrial growth (Darkoh, 1994). the main urban area of Tanzania, Dar es Salaam, was for several long decades the main victim of this de-emphasis, largely because it 'remained for Nyerere a reminder of a colonial legacy (Myers, 2011: 44) Scope of the state expanded rapidly into virtually every sector. In 1967, nationalizations transformed the government into the largest employer in the country. It was involved in everything from retailing to import-export trade and even baking. This created an environment ripe for corruption. Cumbersome bureaucratic procedures multiplied and excessive tax rates set by officials further damaged the economy. Enormous amounts of public funds were misappropriated and put to unproductive use. Purchasing power declined at an unprecedented rate and even essential commodities became unavailable. A system of permits (vibali) allowed officials to collect huge bribes in exchange for the vibali. A foundation for systemic corruption had been laid. Officials became widely known as Wabenzi ("people of the Benz"). By mid-1979, corruption had reached epidemic proportions as the economy collapsed. Nyerere's Tanzania
