On March 11, 2004, a series of terrorist attacks on commuter trains in Madrid changed the lives of thousands of people forever. The following is a compilation of representative and moving testimonies of that day, with special attention to the experiences of university students and the reflections of young people who were between 20 and 25 years old in 2004. Included are accounts from students who did not go to class that day (in many cases due to a university strike call in Madrid), testimonies from professors and academic staff, stories of people who were saved by chance, and generational reflections on the emotional, social, and political impact of 11-M. Each testimony is presented with its context (author, date, source) and a summary of its key points or salient quotes.
