Throughout history, world leaders have remained in power for as briefly as a few weeks or as long as several decades. Despite the number of well-known leaders in nations such as the United Kingdom, the United States and Canada remaining in office for long terms, leaders in Africa and the Middle East tend to stay in power longer. Leaders in those areas remain in power for an average of seven to eight years.
