 Popular opposition to war on Iraq in Europe led to a wave of anti-war rallies, which climaxed in an international synchronized anti-war demonstration around the world on February 15, 2003.The largest of these rallies were in Rome, Barcelona, and in London where over one million marched at a rally organised by the Stop the War Coalition.All three of these cities are in countries that were part of the "coalition of the willing" which took part in the war in Iraq.
