Which act passed in 1774 extended Quebec's boundaries into the Ohio Valley and established Roman Catholicism as the official religion?

The Quebec Act, passed in 1774, was significant because it expanded the borders of Quebec into the Ohio Valley, which was a contested territory at the time. This act was particularly controversial among the American colonists, as it not only altered land claims but also established Roman Catholicism as the official religion of the province. This was seen as a direct affront to the predominantly Protestant settlers in the Thirteen Colonies and contributed to growing tensions between the colonies and the British government.

By recognizing Catholicism in an area where many settlers sought to promote Protestant values, the Quebec Act exacerbated fears of religious intolerance and increased the perception that British policies were designed to undermine colonial governance and freedoms. The act also did not provide for any representative government, which was another point of contention for colonists who valued self-governance. Overall, the Quebec Act played a role in shaping the political landscape leading up to the American Revolution by fostering resentment and unity among the colonies against British authority.
