Zimbabwe's veteran leader Robert Mugabe once quipped that he'd rule his country until he turned 100.
But, aged 93, his grip on power seems to be ebbing as tensions erupt between his loyal ZANU-PF party and the military that has helped keep him in office.
First heralded as a liberator who rid the former British colony Rhodesia of white minority rule, Robert Gabriel Mugabe was soon cast in the role of a despot who crushed political dissent and ruined the national economy.
The former political prisoner turned guerrilla leader swept to power in 1980 elections after a violent insurgency and economic sanctions forced the Rhodesian government to the negotiating table.
In office he initially won international plaudits for his declared policy of racial reconciliation and for extending improved education and health services to the black majority.
But his lustre faded quickly.
Mugabe took control of one wing in the guerrilla war for independence -- the Zimbabwe African National Union (ZANU) and its armed forces -- after his release from prison in 1974.
His partner in the armed struggle -- the leader of the Zimbabwe African People's Union (ZAPU), Joshua Nkomo -- was one of the early casualties of Mugabe's crackdown on dissent.
Nkomo was dismissed from government, where he held the home affairs portfolio, after the discovery of an arms cache in his Matabeleland province stronghold in 1982.
Mugabe, whose party drew most of its support from the ethnic Shona majority, then unleashed his North Korean-trained Fifth Brigade on Nkomo's Ndebele people in a campaign known as Gukurahundi that killed an estimated 20,000 suspected dissidents.
It was the seizure of white-owned farms nearly two decades later that would complete Mugabe's transformation from darling of the West into international pariah -- though his status as a liberation hero still resonates in many parts of Africa.
Aimed largely at placating angry war veterans who threatened to destabilise his rule, the land reform policy wrecked the crucial agricultural sector, caused foreign investors to flee and helped plunge the country into economic misery.
At the same time, critics say, Mugabe clung to power through increased repression of human rights and by rigging elections.
