On May 6, 2002, the murder of Pim Fortuyn, a right-wing populist calling for a very strict policy on immigration, shocked the country. His party became a major political force after the elections, significantly changing the political landscape. However, lack of leadership and fighting within the party caused them to lose much of their following in elections the next year. Another political murder took place on November 2, 2004, when film director and publicist Theo van Gogh was assassinated by a Dutch-Moroccan Islamic extremist. This sparked debate about Islamic extremism in the Netherlands, and on immigration and integration (or lack thereof) as well.
