Eventually, the United Nations General Assembly recognized SWAPO as the sole and authentic representative of the people of Namibia.

[9] He and his team were responsible for starting the institute, whose primary function was to train cadres who could take over the civil service of Namibia upon independence.

Another important component of the institute was to carry out sectoral research to develop a policy framework for the government of independent Namibia.

[8][9] As Prime Minister Geingob introduced modern management approaches to the government; he was also committed to nature conservation coupled with tourism, and in the early 1990s opened the Ongava Lodge, just south of Etosha National Park.

[16] He then left the Global Coalition for Africa and returned to Namibia to participate in the November 2004 parliamentary election, in which he won a seat.

[19] In November 2007, a few weeks before a party congress, the politburo named Geingob its sole candidate for the position of vice-president of SWAPO.

[22] At SWAPO's 2012 party congress, Geingob was reelected as vice-president on 2 December,[23][24] a result which was considered likely to make him the successor of Hifikepunye Pohamba as president of Namibia in 2015.

[23] As the SWAPO candidate, Geingob was elected President of Namibia by an overwhelming margin on 28 November 2014, receiving 87% of the vote.

[28] In February 2023, Geingob hosted First Lady of the United States Jill Biden, the highest-level official from the U.S. to visit Namibia since Al Gore in 1996.

[30] After the Supreme Court of Namibia ruled in favor of equal treatment for two foreign same-sex spouses of Namibian citizens in May 2023, Geingob did not sign a bill passed by the National Assembly that sought to invalidate the verdict.

[9] In January 2024, Geingob supported South Africa's ICJ genocide case against Israel, saying that "No peace-loving human being can ignore the carnage waged against Palestinians in Gaza.

"[31] He also criticized Germany for supporting Israel, citing the Herero and Nama genocide by colonial authorities in then-German South West Africa.

According to bank records analyzed by OCCRP, front companies set up by SWAPO proxies transferred $4.5m through this scheme between July 2017 and November 2018.

[37] He regularly attended the Namibia Annual Music Awards (NAMAs), and in his youth sang in a choir, and played in a band.

[39] Geingob later married Loini Kandume, a businesswoman, on 11 September 1993, in Windhoek, in a high-profile marriage that resulted in two children: a daughter and a son.

[44] On 4 February, Vice President Nangolo Mbumba announced that Geingob had died at Lady Pohamba Hospital in Windhoek, where he had been receiving treatment.

[45] Minister of Environment, Forestry, and Tourism Pohamba Shifeta subsequently disclosed that Geingob had told him in December 2023 that he had only six months to live.

[46] Mbumba was formally sworn into office as acting President of Namibia at a hastily arranged ceremony at State House in Windhoek, about 15 hours after Geingob's death.

During the mourning period, Geingob was laid at the State House, his private residence of Casa Rosalia, and Parliament Gardens, with processions held in Windhoek during the transfers.

His funeral on 25 February 2024 was attended by at least 20 heads of state, including those of Qatar, Tanzania, Germany, Finland, South Africa, Angola, Botswana, Burundi, Democratic Republic of Congo, Kenya, Ghana, Lesotho, Madagascar, Malawi, Mozambique, Sierra Leone, Zambia and Zimbabwe.

He also examined the efforts of Namibians to build a society out of diverse and stratified racial and ethnic groups that were often opposed to each other, to promote democracy and a policy of reconciliation, to improve the condition of the previously disadvantaged groups through affirmative action, to encourage good governance, to promote a culture that respects human rights, and to build state institutions that support these policies.

Geingob traveled extensively covering all the continents and attended, chaired, and presented papers at numerous UN and other international conferences.
