Historical Map of North America & the Caribbean

The surge in migrants heading west put increasing pressure on the Oregon Trail. To secure the Trail, the US government signed the Treaty of Fort Laramie with the tribes of the Great Plains, who agreed to guarantee the safe passage of travelers and allow for the construction of forts in return for an annuity. Promised for fifty years, the Treaty barely lasted five before settlers and prospectors were spilling off the Trail in search of land and gold.

Main Events

Commissioners John Russell Bartlett of the United States of America and General Pedro Garcia Conde of the United Mexican States agree to a compromise border in the disputed Mesilla strip; Bartlett is overruled by the principal US Surveyor Andrew B.
