A. It encouraged expansion by granting low-cost land to settlers
It ended with the exchange of ratifications of the Treaty of Ghent. In 1812, with President Madison in office, Congress declared war against the British. The war began with an attack on Canada, both as an effort to gain land and to cut off British supply lines to Tecumseh's Indian confederation, which had long troubled the US.
Assuming that this is referring to the same list of options that was posted before with this question, the proper answer would be "(2) The United States is ignoring the threat <span>caused by foreign aggression."</span>
Answer:
This is what Bing says
"The Royal Proclamation of 1763 was issued by King George III on October 7, 1763. It followed the Treaty of Paris, which formally ended the Seven Years' War and transferred French territory in North America to Great Britain. The Proclamation forbade all settlements west of a line drawn along the Appalachian Mountains, which was delineated as an Indian Reserve. Exclusion from the vast region of Trans-Appalachia created discontent between Britain and colonial land speculators and potential settlers. The proclamation and access to western lands was one of the first significant areas of dispute between Britain and the colonies and would become a contributing factor leading to the American Revolution. The 1763 proclamation line is similar to the Eastern Continental Divide's path running northwards from Georgia to the Pennsylvania–New York border and north-eastwards past the drainage divide on the St. Lawrence Divide from there northwards through New England."
