15 February 2003 anti-war protests
Some of the largest protests took place in Europe. The protest in Rome involved around three million people, and is listed in the 2004 Guinness Book of World Records as the largest anti-war rally in history. Madrid hosted the second largest rally with more than 1.5 million people protesting the invasion of Iraq; Mainland China was the only major region not to see any protests on that day, but small demonstrations, attended mainly by foreign students, were seen later.
