Step 1: Nepal's Transition to a Democratic Republic
Nepal officially transitioned to a democratic republic in 2008 following the abolition of the monarchy. The monarchy's end, after centuries of rule, was formalized post a decade-long civil war and the 2006 Comprehensive Peace Agreement. The constituent assembly, elected in 2008, formally abolished the monarchy, establishing Nepal as a federal democratic republic.
