Abstract
Multiculturalism has always been one of the characteristics of the United Kingdom. For ages, multiculturalism, immigration, aliens, have been crucial topics, source of debates and interrogations in this country. As foreigners have more or less been accepted, there was some legislation or some events, which tried to influence on their integration. Each of us know what happened on September 11th 2001 in the USA, when the Twin Towers were destroyed by the crash of two planes, a crime claimed by Muslim members of the terrorist association Al Qaeda, led by Osama Bin Laden. 4 years later, the drama took place a second time: in the London's subway, a bomb exploded, where over 50 people died.
