In both Russia and Ukraine, millions of Internet users engage in virtual, combat-like quests for "what really happened" in Soviet history. Embracing digital discourses of hostility and nationalism,¹ they endlessly debate conflicting memories of the countries' "chosen traumas"² in blogs, Twitter, and on other social media. Using digital memory—the name commonly given to commemorative practices as they are mediated online—as the guiding tool, this chapter tackles war-like memory practices in Russian and Ukrainian new media, focusing in particular on social networking sites. Eastern Europe is a geopolitical territory where cultural memory is particularly important and volatile, and its ongoing memory wars and their important subcategory, web wars, deserve thorough study.
