and helped build the TAZARA Railway from Dar es Salaam to Zambia. Nonetheless, from the late 1970s, Tanzania's economy took a turn for the worse, in the context of an international economic crisis affecting both developed and developing economies. In 1978, the neighbouring Uganda, under the leadership of Idi Amin, invaded Tanzania. This disastrous invasion would culminate in Tanzania invading Uganda with the aid of Ugandan rebels and deposing Idi Amin as a result. However, the war severely damaged Tanzania's economy. Through the 1980s, conservation oriented national parks such as Serengeti and Kilimanjaro, with Mount Kilimanjaro as the tallest freestanding summit on Earth, were included on the UNESCO World Heritage List. From the mid-1980s, the regime financed itself by borrowing from the International Monetary Fund and underwent some reforms. Since then, Tanzania's gross domestic product per capita has grown and poverty has been reduced, according to a report by the World Bank. In 1992, the Constitution of Tanzania was amended to allow multiple political parties. In Tanzania's first multi-party elections, held in 1995, the ruling Chama Cha Mapinduzi won 186 of the 232 elected seats in the National Assembly, and Benjamin Mkapa was elected as president. The presidents of Tanzania since Independence have been Julius Nyerere 1962–1985, Ali Hassan Mwinyi 1985–1995, Benjamin Mkapa 1995–2005 Jakaya Kikwete 2005–2015 John Magufuli 2015–2021 and Samia Hassan Suluhu since 2021. After the long tenure of president Nyerere, the Constitution has a term limit: a president can serve a maximum of two terms. Each term is five years. Every president has represented the ruling party Chama cha Mapinduzi (CCM). President Magufuli won a landslide victory and re-election in October 2020. According to the opposition, the election was full of fraud and irregularities. On 17 March 2021, President John Magufuli died from heart complications while in office. Magufuli's vice president, Samia Suluhu Hassan, became Tanzania's first female president.
