A number of legal reforms have been made under the influence of these movements, starting from the 1970s when Egypt and Syria amended their constitutions to specify Sharia as the basis of legislation. The Iranian Revolution of 1979 represented a watershed for Islamization advocates, demonstrating that it was possible to replace a secular regime with a theocracy. Several countries, including Iran, Pakistan, Sudan, and some Nigerian states have incorporated hudud rules into their criminal justice systems, which, however, retained fundamental influences of earlier Westernizing reforms. In practice, these changes were largely symbolic, and aside from some cases brought to trial to demonstrate that the new rules were being enforced, hudud punishments tended to fall into disuse, sometimes to be revived depending on the local political climate. The supreme courts of Sudan and Iran have rarely approved verdicts of stoning or amputation, and the supreme courts of Pakistan and Nigeria have never done so. Nonetheless, Islamization campaigns have also had repercussions in several other areas of law, leading to curtailment of rights of women and religious minorities, and in the case of Sudan contributing to the breakout of a civil war.
