The Republic Protests (Turkish: Cumhuriyet Mitingleri) were a series of peaceful mass rallies that took place in Turkey in 2007 in support of a strict principle of state secularism.
The first rally took place in Ankara on 14 April 2007, just two days before the start of the presidential election process. The second one took place in Istanbul on 29 April. The third and fourth rallies took place consecutively in Manisa and Çanakkale on 5 May. The fifth rally took place in İzmir on 13 May.
In Turkey, secularism or laicism (see laïcité) was first introduced with the 1928 amendment of the Constitution of 1924, which removed the provision declaring that the "Religion of the State is Islam", and with the later reforms of Turkey's first president Mustafa Kemal Atatürk, which set the administrative and political requirements to create a modern, democratic, secular state, aligned with Kemalism.
Nine years after its introduction, laïcité was explicitly stated in the second article of the then Turkish constitution on 5 February 1937. The current Constitution of 1982 neither recognizes an official religion nor promotes any.
