The JUI-F is part of the Deobandi movement and was formed in 1945, when its leaders broke away from Jamiat Ulema-e Hind. The reason being for the split was that the JUI leaders supported the formation of Pakistan. The JUI later split into two groups, one was led by Sami ul-Haq and the other by Fazal ur-Rehman. The party has considerable influence in Khyber Pakhtunkhwa and has been part of coalition governments formed at federal and provincial levels.
