The image, by Morgenavisen Jullands-Posten cartoonist Kurt Westergaard, was one of 12 cartoons about the Prophet Mohammed, one of which depicted the prophet wearing a bomb as a turban with a lit fuse.

This led to protests across the Muslim world, some of which escalated into violence with police firing on the crowds (resulting in more than 100 deaths, altogether), including setting fire to the Norwegian and Danish Embassies in Syria, storming European buildings, and desecrating the Danish, Norwegian and German flags in Gaza City. While a number of Muslim leaders called for protesters to remain peaceful, other Muslim leaders across the globe, including Mahmoud al-Zahar of Hamas, issued death threats. Various groups, primarily in the Western world, responded by endorsing the Danish policies, including "Buy Danish" campaigns and other displays of support. Danish Prime Minister Anders Fogh Rasmussen described the controversy as Denmarks’s worst International crisis since World War II.

Supporters have said that the cartoons illustrated an important issue in a period of Islamic terrorism and that their publication is a legitimate exercise of the right of free speech, explicitly tied to the issue of self-censorship. They claim that Muslims were not targeted in a discriminatory way since unflattering cartoons about other religions are frequently printed. They question whether some of the riots were spontaneous outpourings as they took place where no spontaneous demonstrations are allowed, and whether the images of Muhammad per se are offensive to Muslims, as thousands of illustrations of Muhammad have appeared in books by and for Muslims.
