John Joseph Magufuli started his education at The Chato Primary School from 1967 to 1974 and went on to The Katoke Seminary in Biharamulo for his secondary education from 1975 to 1977 before relocating to Lake Secondary School in 1977 and graduating in 1978. He joined Mkwawa High School for his Advanced level studies in 1979 and graduated in 1981. That same year he joined Mkwawa College of Education (a constituent college of the University of Dar es Salaam) for a Diploma in Education Science, majoring in Chemistry, Mathematics and Education.

Magufuli earned his bachelor of science in education degree majoring in chemistry and mathematics as teaching subjects from the University of Dar es Salaam in 1988. He also earned his masters and doctorate degrees in chemistry from The University of Dar es Salaam, in 1994 and 2009, respectively. In late 2019, he was awarded an honorary doctorate by the University of Dodoma for improving the economy of the country.

John Joseph Magufuli ventured into elective politics after a short period as a teacher at The Sengerema Secondary School between 1982 and 1983. He taught chemistry and mathematics. Later on, he quit his teaching job and was employed by The Nyanza Cooperative Union Limited as an industrial chemist. He remained there from 1989 to 1995, when he was elected as Member of Parliament (MP) representing Chato district. He was appointed Deputy Minister for Works in his first term as MP. He retained his seat in the 2000 election and was promoted to a full ministerial position under the same docket. After President Jakaya Mrisho Kikwete was requested to take office, he moved John Joseph Magufuli to the post of Minister of Lands and Human Settlement on 4 January 2006. Subsequently, he served as Minister of Livestock and Fisheries from 2008 to 2010 and again as Minister of Works from 2010 to 2015.

On 12 July 2015 Magufuli was nominated as CCM’s presidential candidate for the 2015 election, winning the majority votes against his opponent Justice Minister and former United Nations Deputy Secretary General Miss Asha-Rose Migiro and the African Union Ambassador to the United States of America, Miss Amina Salum Ali for the party’s nomination.

Although Magufuli faced a strong challenge from opposition candidate and previous CCM political party member Edward Lowassa in the election, held on 25 October 2015, Magufuli was declared the winner by the National Electoral Commission (NEC) on 29 October; he received 58% of the vote. His running mate, Samia Suluhu, was also declared Vice President. He was sworn in on 5 November 2015.

On 10 December 2015, more than a month after taking office, Magufuli announced his cabinet. Its size was reduced from 30 ministries to 19 to help reduce costs.

On 12 April 2016, Magufuli conducted his first foreign visit to Rwanda, where he met his Rwandan counterpart Paul Kagame and inaugurated the new bridge and one-stop border post at Rusumo. Magufuli also attended the memorial of the 22nd anniversary of the Rwandan genocide.

In July 2016, Tanzania banned shisha smoking, with Magufuli citing its health effects among youth as the reason. In March 2017, Tanzania banned the export of unprocessed ores, in an effort to encourage domestic smelting. In January 2018, Magufuli issued a directive ordering the suspension of registration for foreign merchant ships, following recent incidents surrounding the seizure of overseas shipments of illegal goods (particularly drugs and weapons) being transported under the flag. Tanzania and Zanzibar had gained reputations for being flags of convenience.In the same year, He introduced a fee free education for all the government schools in 2016.

Magufuli’s government has been accused of repressing opposition to his leadership, including laws restricting opposition rallies, the suspension of the Swahili-language Mawio newspaper in 2016 for publishing “false and inflammatory” reporting regarding the nullification of election results in Zanzibar, threatening to shut down radio and television stations that do not pay licence fees, and a 2018 bill requiring blogs and other forms of online content providers to hold government licenses with content restrictions. A devout Catholic, he has been publicly criticized by the Conference of Catholic Bishops of Tanzania for taking measures that suppress constitutional freedoms and, in the view of the bishops, represent a threat to national unity.

People convicted of same-sex liaisons in Tanzania can be jailed for up to 30 years. In October 2016, the Tanzanian government banned HIV/AIDS outreach projects and closed US-funded programs that provide HIV testing, condoms and medical care to the gay community. The countrywide closure of private HIV clinics began soon afterward. In late 2018, Magufuli initiated a nationwide crackdown, threatening to arrest and deport anyone campaigning for gay rights and making it difficult to find a lawyer who will defend cases of violence against LGBTQ people.

In September 2018, John Magufuli told a rally: “Those going for family planning are lazy … they are afraid they will not be able to feed their children. They do not want to work hard to feed a large family and that is why they opt for birth controls and end up with one or two children only.” He urged people not to listen to those advising about birth control, some of it coming from foreigners, because it has sinister motives. The statement has drawn criticism from Amnesty International and others.

In July 2020 Magufuli was nominated as the CCM’s presidential candidate in elections scheduled for October 2020. His nomination was not opposed after the expulsion from the party earlier in the year of Bernard Membe, a former foreign minister who had planned to challenge the nomination. He received the highest votes and was therefore re-elected to extend his presidency until 2025 for a second term.

The country has amended the laws governing the award of mining contracts, giving itself the right to renegotiate or terminate them in the event of proven fraud. The new legislation also removes the right of mining companies to resort to international arbitration. The tax dispute with Acacia Mining, accused of having significantly undervalued its gold production for years, finally resulted in an agreement: Tanzania obtains 16% of the shares in the mines held by the multinational. In May 2020, Acacia Mining paid $100M to the government to end dispute as the first tranche of the $300M. However, this anti-corruption policy has also “frightened investors, who now fear they will have to deal with Tanzanian justice, and weakened growth,” according to Zitto Kabwe, one of the leaders of the opposition ACT party. With one of the highest economic growth rates on the African continent (5.8% in 2018 and an estimated 6% for 2019 according to the IMF), the Tanzanian government is embarking on a vast program of infrastructure development, particularly rail infrastructure. The small fishing port of Bagamoyo, to which $10 billion of investment has been allocated, is expected to become the largest port in Africa by 2030.
