3. Yoweri Kaguta Museveni (Uganda) – in power for 31 years
At the Kenya-Uganda border of Busia, on the Ugandan side, there used to be a billboard that read: Yoweri Kaguta Museveni, protecting you from rebels since 1986, with the photo of Museveni looking at you as you get in. Yoweri Kaguta Museveni 73 years, got into office in 1986 after toppling Milton Obote through concerted rebellion and guerrilla attacks. He has been protecting Uganda from rebels since. His main political challenger, Kiza Bessigye has repeatedly been thrown in jail and harassed by the police. He is known for being very generous with government posts to his family members.
