[799] The ordinals following the names of Byzantine emperors are a cause of confusion, as there is no universal agreement as to the method of numbering. Some historians count by sovereigns of the same family bearing a particular name (i. e. John I Palaeologos and John II Palaeologos), while others number by the imperial line as a whole (i. e. John V Palaeologos, John VI Cantacuzenos, John VII Palaeologos). I have used the second system.
