Another important factor in the causes of the American Revolution was the so-called "Quebec Act." This act John Adams asserted constituted a "frightful system," and James Rowdoin pronounced it to be "an act for encouraging and establishing Popery." The policy of this legislation may be doubted. Of its justice there can be no doubt. The establishment of the Catholic clergy in Canada and their resultant domination has entailed many disadvantages upon the governing powers of the dominion. But at the time the law was passed it was a simple act of justice. Had Parliament refused to do this it would have been guilty of that tyranny charged against it by the Revolutionists, and today the dominion would not be a part of the British Empire. To the student of American history it at first seems very strange and unaccountable why at the outbreak of the Revolution, the recently conquered French provinces were not the first to fly to arms, especially as their mother country, France, had espoused the cause of the Revolutionists. Instead of this the French Canadians remained loyal to their conqueror and resisted by force of arms all attempts to conquer Canada. The explanation of this curious state of affairs is the "Quebec Act." By this act the French Canadians were to retain their property, their language, their religion, their laws, and to hold office. In fact, they were allowed greater liberty than they had when subject to France. All this was allowed them by the British Parliament, and this was resented by the English colonists, for they were not allowed to confiscate their lands and drive out the inhabitants as the New Englanders did when they conquered Nova Scotia, New Brunswick, and Prince Edward Island. They also claimed that by the laws of the realm Roman Catholics could not vote, much less hold office. At a meeting of the first Continental Congress, held October 21, 1774, an address to the people of Great Britain was adopted, setting forth the grievances of the colonies, the principal one of which was as follows: "Nor can we suppress our astonishment that a British Parliament should ever consent to establish in that country a religion that has deluged your island in blood and dispersed impiety, bigotry, persecution, murder and rebellion through every part of the world, and we think the legislature of Great Britain is not authorized to establish a religion fraught with such sanguinary and infamous tenets."
