As the enlargement of the European Union (EU) increases the scope and population of Europe, social integration has been pushed to the forefront of political debate. Over the past decade, incidents such as the murder of Theo van Gogh by Mohammed Bouyeri in 2004 or the political furor caused by the French ban on hijab in 2003 call into question Europe's ability to successfully integrate its diverse minority populations. When the EU took steps to move beyond an economic free trade area to a unified political entity, it strived to create a European identity shared by all of its citizens. However, the opening of borders between all member countries, which was intended to promote freedom of travel and the integration of nations, has instead heralded anti-immigrant sentiment that could undermine the entire project if given a chance to develop. Now, the steady flow of migrants from both within the EU and abroad exacerbates tensions with minority populations that must be solved before the continent welcomes further expansion.
