Lists of emperors
This is a list including all rulers who had carried the title of emperor or who ruled states generally regarded as empires in the constitutional or dynastic sense. It excludes rulers whose states are described as colonial empires solely because of their overseas possessions, such as the British, French, Dutch, Spanish and Portuguese empires, unless they also held an explicit imperial title, as the British monarchs did through the title Emperor (or Empress) of India between 1876 and 1947.
