As the art biennial opens, the smell of violence once again lies in the air in Istanbul. Can a major exhibition respond to the language of the street and fulfil its promise of a free and modern society? By Catrin LorchMore
In the autumn of 1989, Dresden was one of the East German cities that became known worldwide for the peaceful "Monday demonstrations" against the government of the GDR that precipitated the fall of the Berlin Wall a few months later. One of the slogans chanted by the protesters at the time was "Wir sind das Volk" (We are the people). Twenty-five years on, a very different movement began organising weekly Monday demonstrations and chanting "Wir sind das Volk". In this photo gallery, we chart some of the reactions to Pegida and the developments relating to this anti-immigration and anti-Islam movement.
