The history of Berlin’s “Loveparade is the stuff of myth, as documented in countless guidebooks and Web sites. The first Loveparade, in July 1989, was actually staged as a political demonstration, and it attracted a crowd of about 150. Over time the parade grew and grew, the number of attendees skyrocketing for more than a decade. According to the Loveparade Web site (loveparade.net), the event has had more than 8.8 million visitors since its creation and has attracted some of the world’s most famous D.J.’s.” But changes this year have some of the original organizers protesting.
