Eight candidates contested the presidential elections. Four candidates were from a generation called the Bush War revolutionaries, and were part of the guerrilla armies that toppled the previous government in 1986. Yoweri Museveni was running for his seventh term in office in 2016. He took power in 1986 after winning a guerrilla war against President Tito Okello. Museveni has been president for 30 years in a country where 78% of the population was under the age of 30 at the time of the elections. Museveni's main rival was four-time rival Kizza Besigye, who ran under the Forum for Democratic Change ticket and has lost the past three elections against Museveni. Besigye was Museveni's personal physician and a military officer who broke ties with the NRM government in 2001.
