Geert Wilders (Dutch pronunciation:  or ; born 6 September 1963) is a controversial Dutch politician and leader of the Party for Freedom, a party in The Netherlands. Born in the city of Venlo and raised as a Roman Catholic, Wilders attributes his politics to his support for what he calls 'Judeo-Christian values'. He formed many of his political views in his travels to Israel, as well as the neighboring Arab countries and his early job at the Dutch social insurance agency moved him to politics, where he worked as a speechwriter for the liberal People's Party for Freedom and Democracy. In 1996, he moved to the city of Utrecht, and was elected in the city council, and later the House of Representatives of the Netherlands.

Citing irreconcilable differences on the party's position on Turkish accession to the European Union, Wilders left the People's Party in 2004 to form his own party, the Party for Freedom. Since then, he has been outspoken on a number of issues such as immigration, freedom of speech, the fundamental beliefs of Islam, and the behavior of Moroccan youth in the cities. His controversial 2008 film about Islam in the Netherlands, Fitna, has received international attention. On 21 January 2009, the Amsterdam Court of Appeal ordered his prosecution for what it said was "the incitement to hatred and discrimination". Wilders has also been banned from entering the United Kingdom since 12 February 2009, with the Home Office viewing his presence as a "threat to one of the fundamental interests of society". That ban was lifted on 13 October 2009.

Wilders was born in the city of Venlo, Netherlands in the province of Limburg on the southern Dutch border with Germany. He is the youngest of four children. His father worked as a manager for the printing and copying manufacturing company Océ. His father fled the area to escape from the Nazis and became so traumatized from the experience that he refused to physically enter Germany even forty years later. Wilders speculates that his father may have had some Jewish ancestry.
