The fall of the Berlin Wall and the subsequent reunification of Germany were met with a mixture of euphoria, anxiety and hope, inspiring a desire for an end to walls and militarized borders around the world. In retrospect, we were closer to a world without border walls in 1989 than we are today. Presently, over 70 walls separate nations and states— 50 of which were constructed following Sept. 11, 2001. This conference will explore the reasons for the proliferation of walls, their impacts on migration, citizenship and possibilities for peace as well as their role in reconfiguring border landscapes and communities.
