Religious reform refers to movements aimed at improving or changing practices and beliefs within a religious tradition. These reforms often arise in response to perceived corruption, moral decline, or a desire for a more authentic expression of faith. Notable examples include the Protestant Reformation in the 16th century, which challenged the authority of the Catholic Church and led to the establishment of various Protestant denominations. Reform movements can also occur within other religions, such as Islamic reform efforts that seek to return to the original teachings of the Quran and Hadith. These movements may advocate for social justice, gender equality, or a reinterpretation of religious texts to align with contemporary values.
