Bagaza initiated a number of reforms after taking power, attacking corruption and making modest reforms to improve conditions for Hutus who had been targeted under the Micombero regime. He earned respect for his work ethic, as he "drove himself to work at 7:30 a.m. each day" instead of travelling in large cavalcades as most regional politicians did at the time. Some Hutu refugees were allowed to return from exile in Zaire and Tanzania where they had fled during the genocide. Bagaza granted a few government posts to Hutu, appointing two Hutu ministers in his first cabinet. Burundi's feudal system of land tenure, known as the Ubugererwa, was abolished in 1977. Some Tutsi-held land was transferred to Hutu farmers. However, Bagaza ensured that the Tutsi remained economically and politically dominant. A programme of economic modernization was begun to allow the emergence of small-scale capitalist agriculture, involving the construction of two new hydroelectric dams which still form the basis for Burundi's energy infrastructure. He also initiated road building programs, expanded the availability of drinking water, and developed a port on Lake Tanganyika. His infrastructure investments helped to shape Burundi's export ecenomy which came to rely on coffee, tea and sugar. Internationally, Bagaza successfully maneuvered between different political factions, securing economic aid from the Western Bloc, the Eastern Bloc, China, and the Arab world. Bagaza's regime introduced a new national constitution in 1981 which consolidated Burundi as a one-party dictatorship under the Union for National Progress (Union pour le Progrès national, UPRONA), which he re-organised under his own leadership. In the election of 1984, he was re-elected president with 99.6 percent of the national vote. After the election, Bagaza organized a military operation against the Catholic Church in Burundi, regarding it as a threat to his power. The Church was increasingly targeted as the regime became increasingly repressive. Foreign missionaries were expelled and attempts were made to break its influence over the public and education. Bagaza banned Catholic media and church services, closed Church-run literacy centers, and ordered the arrest and torture of Church figures. He also tried to implement other "eccentricities" such as restricting bar openings and officially limiting the time as well as money Burundians were allowed to spent for traditional betrothal and mourning ceremonies. Bob Krueger argued that these policies ultimately alienated too many Burundians and led to Bagaza's deposition. Deposition and involvement in democratic politics A military coup broke
