The Principality of Chiarn was a breakaway government established by Jorgen Sekirol in the Hafan Sector, in the galactic core. It briefly seceded from the Galactic Empire in 14 ABY in the midst of the Imperial Blitzkrieg and culminated in the Moff Sekirol Crisis.
The Principality was led by Moff Sekirol. It was defeated at the Battle of the Gate of Thrawn, and Chiarn was brought back under Imperial control.
