On October 31st 1517 Martin Luther published his 95 Theses, his Disputation on the Power and Efficacy of Indulgences, his criticism of the contemporary Catholic church. 95 theses which fired a debate and discourse that, ultimately, led to the splitting of the, until then, all-powerful Catholic church, an event which was to have consequences far, far, beyond religious practice and power, and which was arguably one of the single most important moments in the development of European society.

According to the popular telling of (hi)story, Martin Luther published his 95 Theses by…… nailing them to the door of the Schlosskirche in Wittenberg.

With the exhibition From Luther to Twitter. Media and the Public Sphere the Deutsches Historisches Museum, Berlin, explore developments in the nature of public debate and discourse and the role of evolving media and technology in those developments.
