Tehreek-e-Nafaz-e-Shariat-e-Mohammadi (TNSM, English: Movement for the Enforcement of Islamic Law) is a Pakistani militant group whose objective is to enforce Sharia law in the country. The rebel group took over much of Swat in 2007. It was founded by Sufi Muhammad in 1992, and was banned by President Pervez Musharraf on January 12, 2002.
The organization is active in the areas along the Pakistan-Afghanistan border, especially Swat and Malakand but including Dargai and Chenagai. It supports the Taliban forces in neighbouring Afghanistan. It has been described as "one of the most dangerous religious militant groups in Pakistan." When the founder was imprisoned on January 15, 2002, Maulana Fazlullah, his son-in-law, assumed leadership of the group. Sufi Muhammad was freed in 2008 after he renounced violence.
