In 1959, Clemens Kapuuo was a founding member of the
South West African National Union (SWANU), Namibia's first nationalist political party, formed as an umbrella body for anti-colonial resistance groups including the
Ovamboland People's Organization (OPO), SWAPA, the DEC and the
Herero Chiefs' Council among others. On 27 September 1959, SWANU was officially launched at a public meeting in Windhoek with the backing of the Herero Chiefs' Council under
Hosea Kutako, and OPO under
Sam Nujoma and
Jacob Kuhangua.
Jariretundu Kozonguizi was elected president, and the executive office included representatives from OPO, SWAPA, the Herero Chiefs' Council, and DEC representing the Damara community under
Fritz Gariseb. That same year, Kapuuo led the opposition to the forced relocation of black Namibians from the Old Location to
Katutura and witnessed the
Old Location Uprising. Kapuuo resigned as a teacher in 1960 when he was appointed deputy chief to
Hosea Kutako. The Herero Chiefs' Council also appointed him as the automatic successor to Hosea Kutako, who was then old, as they feared that the South African authorities would try to take advantage of the death of Kutako to impose their own nominee as chief. That same year, he helped Sam Nujoma go into exile, facilitating his escape from South African authorities. In 1964, the Herero Chiefs' Council withdrew from SWANU and helped form the
National Unity Democratic Organisation (NUDO), so that the council as such would not have to be directly involved in politics. The founding leader was
Mburumba Kerina, but after disagreements with the Chiefs' Council, Kerina was replaced by Kapuuo. Following the decision of the
International Court of Justice at the Hague in 1971 that South African rule in Namibia was illegal, Kapuuo, as the leader of NUDO was instrumental in forming the
National Convention. The National Convention included
SWAPO under
David Meroro, SWANU under
Gerson Veii and several other political groups, and demanded an immediate take-over of Namibia by the
United Nations in preparation for independence. In 1973, however, the United Nations declared SWAPO the sole authentic representative of the people of Namibia, and this soured relations between NUDO and SWAPO. Kapuuo objected on the grounds that the
Ovambo, who made up the majority of members of SWAPO, had not been dispossessed of their land under German and South African rule as the
Hereros had, and were therefore relatively privileged newcomers to the country's independence movement. Kapuuo officially succeeded Hosea Kutako as paramount chief of the Herero people on 20 July 1970. However, his leadership was contested by Jephta Maharero, who led the Association for the Preservation of the Tjamuaha-Maharero Royal House. After the National Convention collapsed in 1974, Kapuuo participated in the South African-led
Turnhalle Constitutional Conference held in Windhoek from 1975 to 1977, which aimed to establish a multi-racial government for Namibia. On 5 November 1977, the
Democratic Turnhalle Alliance (DTA) was formed as a counterbalance and main opposition to the SWAPO. Kapuuo was voted as DTA's first President and Dirk Mudge its Chairman. The DTA comprised several ethnically-based parties, including the
Republican Party, and Kapuuo's NUDO among others. ==Death==
