Arab Spring The Arab Spring, (Arabic: الربيع العربي‎ ‎ "ar-Rabīʻ al-ʻArabī") also referred to as Arab revolutions (Arabic: الثورات العربية‎ ‎ "aṯ-'awrāt al-ʻarabiyyah"), was a revolutionary wave of both violent and non-violent demonstrations, protests, riots, coups and civil wars in North Africa and the Middle East that began on 17 December 2010 in Tunisia with the Tunisian Revolution.
Solution process Solution process (Turkish: "Çözüm süreci" ), also known as the Kurdish–Turkish peace process, was a peace process, which had aimed to resolve the long-running Kurdish–Turkish conflict (1978-present). The conflict has been ongoing since 1984 and resulted in some 40,000-100,000 mortal casualties and great economic losses for Turkey as well as high damage to the Kurdish population. Though there was a unilateral cease-fire between 1999 and 2004, the sides failed to gain understanding and the conflict became increasingly violent. The 2013 truce was working until September 2014, when the relations became strained due to spillover of the Syrian Civil War; the truce fully collapsed in July 2015, with the renewed full-scale warfare in South-Eastern Turkey.
