The Twelve Kingdoms Era was a period of Tapani history from circa 11,708 BBY to 7328 BBY. Over the generation the clan worlds grew more independent of the central government on Pelagon and power gradually decentralized to the local clan capitals. Traditional Tapani historians placed this transition quite arbitrarily in the year 11,708 BBY (1,012 Tapani calendar), although others argued that shift to the Twelve Kingdoms Era happened much earlier.
