Krum
Krum the Horrible (Bulgarian: Крум Страшни) was khan of Bulgaria, from after 796, but before 803, to 814 AD. During his reign the Bulgarian territory doubled in size, spreading from the middle Danube to the Dnieper and from Odrin to the Tatra Mountains. His able and energetic rule brought law and order to Bulgaria and developed the rudiments of state organization.
