Among the turning points that shaped the historical image of the world, the October Revolution with its long-lasting social, economic, and political consequences has been attracting the attention of historiographers around the world as well as in Slovenia, influencing the policy-making and spurring the interest of a wide public circle for the last one hundred years. At the time of the Revolution the established political order was shaken, a “global revolution of rising expectations” broke out, and it eventually reached the furthest ends of the globe. War, national movements, and social/class discontent were simultaneously disintegrative and creative, opening new opportunities, inspiring new ways of thinking, and shaping new mental worlds. The historical importance of these events was also clearly demonstrated by the radical ideological and political movements stemming from modernity which understood the October Revolution in Petrograd either as a starting point or an emphasised purpose for their activities. This centenary provides us with a marvellous opportunity to debate the new findings and evaluate the existing ones, brought about by the research endeavours with regard to this specific issue. The Institute of Contemporary History has thus decided to organise a round table about the October Revolution, in order to contemplate the various questions surrounding this topic nowadays. We shall present the viewpoints expressed by the international historiography as well as those shaped in the Slovenian space.
