Twenty years ago, riot police moved in to break up anti-communist speeches at Prague University, triggering a series of demonstrations and strikes that would eventually lead to the installment of the first non-communist government in the country since 1948 and the election of playwright and dissident Vaclav Havel as president before the end of the year.
