March 29 (Reuters) - Zimbabwe's Robert Mugabe, in power since 1980, faces a tough challenge in Saturday's presidential vote being held alongside parliamentary and municipal ballots. Following is a chronology of Zimbabwe's decade of troubles: 1998 - An economic crisis marked by high interest rates and inflation provokes riots and increasing support for the Zimbabwean Congress of Trade Unions headed by Morgan Tsvangirai. 1999 - The opposition Movement for Democratic Change (MDC) is formed and Tsvangirai is appointed leader. 2000 - Voters back the MDC and turn down a proposed constitutional amendment which would have given the president more power. -- Mugabe's ruling ZANU-PF wins a parliamentary election amid charges of fraud and vote-rigging by the opposition. -- Thousands of independence war veterans and their allies, backed by the government, seize white-owned farms, saying the land was illegally appropriated by white settlers. 2001 - Government agrees to stop often violent land invasions in exchange for British funds to finance land reform. Mugabe later rejects criticism he has ignored the deal. 2002 - Mugabe wins election pitting him against Tsvangirai. Observers condemn poll as flawed and unfair. Commonwealth suspends Zimbabwe. 2003 - IMF begins steps to expel Zimbabwe over dues unpaid since 2001. Commonwealth summit agrees to continue suspension, leading Mugabe to pull Zimbabwe out of the organisation. 2004 - High Court acquits Tsvangirai of plotting to assassinate Mugabe and seize power, a ruling condemned by the government. Remaining charges are dropped in August 2005. 2005 - ZANU-PF wins parliamentary election, giving it the majority it needs to change the constitution. -- About 700,000 people lose their homes or livelihoods in the demolition of urban slums. 2007 - Tsvangirai says he was badly beaten after he attempts to attend a banned protest rally, spurring international condemnation of Mugabe's government. 2008 - Mugabe announces presidential and parliamentary elections for March 29, 2008. -- Ruling party member and former finance minister Simba Makoni launches election challenge to Mugabe and is expelled from party. -- Tsvangirai accuses Mugabe of abusing his position to try to rig the vote.
