Russia's full-scale invasion of Ukraine has shone a spotlight on the need for evidence-based, critical discussion of borders and memory-making, grounded in History but speaking to a wider global public. This course will use the historian's toolkit to examine borders and memory-making at war through a global lens. Bringing together undergrads from College Park & from Kyiv, Ukraine, this Global Classroom will both compare & connect different stories across time and space, from the Polish-Ukrainian borderlands, to the US-Mexico border, to Korea, to Rwanda and Uganda. Content delivery will combine once-a-week online, real-time mini-lectures with small-group projects & meetings. These will facilitate collaborative partnerships between US & Ukrainian students.
