The word serhildan describes several Kurdish protests and uprisings since the 1990s that used the slogan "Êdî Bese" ("Enough") against Turkey. Local shops are often closed on the day of demonstrations as a form of protest. Protests are held every year on 15 February, the date of Abdullah Öcalan's capture, and during Newroz on the 21 March, the Kurdish New Year. The Turkish Prime Minister Recep Tayyip Erdogan has thus far refused to acknowledge the demands of the protests, calling them a conspiracy by an alleged Ergenekon–PKK axis.
