Answer:
The Protestant Reformation challenged the authority of the Roman Catholic Church and sparked a major cultural and intellectual shift in Europe. The reformers' ideas about individual freedom of conscience, the interpretation of scripture, and the role of the Church led to the formation of new Protestant denominations and a proliferation of religious and political debates. This helped to lay the foundations for modern secularism and religious pluralism, and contributed to the development of the scientific revolution and the Enlightenment. The Reformation also had profound social and economic effects, including the formation of a middle class and the growth of commerce, as well as the outbreak of wars of religion and the decline of feudalism.
