Mohamed Abdelaziz — Polisario Front leader and SADR president (1947–2016)

Founding of the Polisario and proclamation of the SADR

Abdelaziz was among the generation that founded the Frente Popular de Liberación de Saguía el Hamra y Río de Oro (Polisario Front) in the early 1970s. After Spain's withdrawal from Western Sahara in 1975 and competing claims by Morocco and Mauritania, the Polisario proclaimed the Sahrawi Arab Democratic Republic in 1976. Abdelaziz became Secretary-General of the Polisario Front and President of the SADR, roles he retained until his death.

Armed struggle, ceasefire and the UN process

Under Abdelaziz the Polisario conducted an armed campaign against occupying forces through the late 1970s and 1980s, later accepting a United Nations-brokered ceasefire in 1991. The ceasefire led to the establishment of the UN Mission for the Referendum in Western Sahara (MINURSO), with the declared aim of organising a referendum on self-determination. Abdelaziz consistently pressed for implementation of a referendum and for international engagement on the dispute.

Refugee administration and governance

The Polisario under Abdelaziz organised civil administration for Sahrawi refugees largely based in camps around Tindouf, Algeria. The SADR developed parallel institutions — ministries, schools and social services — intended to serve the refugee population and to assert the structures of a state in exile. The SADR also gained diplomatic recognition from a number of countries and from the Organisation of African Unity (later African Union) during Abdelaziz's tenure.

Diplomacy and international profile

Abdelaziz pursued a dual strategy of armed resistance and sustained diplomacy. He travelled to many countries and cultivated ties with governments, international organisations and solidarity movements sympathetic to Sahrawi independence. The SADR's admission to the OAU in 1984 increased its international profile, shaping regional alignments and drawing sustained international attention to the Western Sahara question.

Criticism, reforms and legacy

Supporters credit Abdelaziz with keeping the Sahrawi cause alive and building administrative capacity in exile. Critics argued that the long duration of his leadership limited internal political pluralism and that a negotiated settlement remained elusive. Nonetheless, his tenure made the Sahrawi dispute a persistent item on international and regional agendas, and he is widely recognised as one of the longest-serving leaders of a liberation movement in contemporary Africa.

Death and succession

Mohamed Abdelaziz died on 31 May 2016 from lung cancer, a development noted across international media and by Sahrawi authorities (reports of his death). He was succeeded as Secretary-General of the Polisario Front and President of the SADR by Brahim Ghali. Abdelaziz's passing marked a significant transition for the movement and prompted renewed diplomatic activity around the Western Sahara conflict.
