In 1967, the Tanzanian government declared the "ujamaa" policy, which made Tanzania lean towards socialism. The move hampered the potential growth of the city as the government encouraged people not to move into cities and instead remain in Ujamaa socialist villages. By the 1980s, the policy failed to combat the increasing poverty and hunger that Tanzania faced, and had delayed necessary development. This situation led to the liberalization policy of the 1980s that essentially ended socialism and silenced its proponents within Tanzania's government.
