A presidential election was held in October 2000 in which Laurent Gbagbo vied with Guéï, but it was not peaceful. The lead-up to the election was marked by military and civil unrest. Following a public uprising that resulted in around 180 deaths, Guéï was swiftly replaced by Gbagbo. Alassane Ouattara was disqualified by the country's Supreme Court, due to his alleged Burkinabé nationality. The existing and later reformed constitution under Guéï did not allow noncitizens to run for the presidency. This sparked violent protests in which his supporters, mainly from the country's north, battled riot police in the capital, Yamoussoukro.
