The document that served as the foundation for religious freedoms and moral governance in medieval times was the Magnus Libertatis, or the “Magna Carta.” Signed in 1215, it established various fundamental rights and limited the power of the monarchy. The Magna Carta introduced principles such as the right to a fair trial and protection from arbitrary detention, which echoed through history as a precursor to modern democratic governance. While it didn’t guarantee religious freedom outright, it laid an important framework for the development of legal rights, contributing to the eventual emergence of more comprehensive liberties.
