"Jamaati Ulama Islam ... figured as a fairly minor part of Pakistan's religious scene until the regime of General Zia al-Haq ... who used an Islamic policy to buttress his military dictatorship. Part of his policy to `Islamize` Pakistan was a campaign to expand religious education with funds for thousands of new madrases. Their number grew from around 900 in 1971 to over 8000 official ones and another 25,000 unofficial ones in 1988. With financial support from Saudi Arabia, Deobandi madrasas were part of this vast proliferation in religious education, much of it located in Afghan refugee camps that sprang up in the 1980s. This rapid expansion came at the expense of doctrinal coherence as there were not enough qualified teachers to staff all the new schools. Quite a few teachers did not discern between tribal values of their ethnic group, the Pushtuns and the religious ideals. The result was an interpretation of Islam that blended Pushtun ideals and Deobandi views, precisely the hallmark of the Taliban."
