The Battle of Tnaka (Hobrazian: ბრძოლა თნაქა Brdzola Tnaka) was a medieval conflict between the Duchy of Muzalkaz and the Zarganid Kingdom of Hobrazia in 799 CE. The Duchy of Muzalkaz was given South Muzalkaz after the Muzalkaz armies crushed the Hobrazians in a short unusual conflict in which a member state attacked an association which it was part of. The battle marked the end of the Zarganid Golden Age, as the kingdom was to collapse a few years later in 815, and Duke Mihr II Ashpagur of Muzalkaz was to proclaim himself King of Muzalkaz.
