For the first time in four decades, the Kurdistan Workers Party, known as the PKK, is laying down its arms and says it will end its insurgency against Turkey. The separatist group’s disbandment comes after its imprisoned leader announced an end to its 41-year armed struggle and a transition to democratic politics.

Turkish President Recep Tayyip Erdogan announced a hopeful shift as the PKK begins disarmament, signaling an end to decades of unrest. The decision follows urging by imprisoned leader Abdullah Ocalan.
