About this Event
“If you look at a map, they drew just a straight artificial line between Canada and the U.S. Somebody did it a long time ago, and it makes no sense” -President Trump, 2025
The Mechanics' Institute is hosting a two-part lecture in its history program to tell the fascinating story of imperial greed, aggression, betrayal and diplomatic bungling that placed the US-Canadian border where it is today.
Part 1: How the War of 1812 divided North America
This talk describes how the boundary lines argued over and delineated in the 1783 Treaty of Paris opened the door to accelerated colonization of Indian lands west of the Appalachians, but growing indigenous resistance dependent on arms and materials traded from British America impeded this invasion. In 1812, at the zenith of Napolean’s power in Europe America seized an opportunity to eliminate its imperial rival from North America by occupying Canada. Militarily it was a fiasco, with five attempts defeated. Then at the war’s conclusion at the Treaty of Ghent America was able to achieve through adroit diplomacy what it was unable to achieve by force; solidified borders, now encompassing the 49 th parallel, that diminished British power and allowed for unimpeded American colonial expansion from sea to sea. But American belligerence had an unanticipated effect, it created a new nation Canada, that resists all attempts at assimilation, permanently dividing the continent.
