==Aftermath==
In the aftermath of Smith's death, President [[Andrew Jackson]], during his second term in 1836, launched the federally-funded oceanic [[United States Exploring Expedition]], led by [[Charles Wilkes]], from 1838 to 1842. One of the expedition's accomplishments was the exploration of the Pacific Northwest and to lay claim on the Oregon Country, which Smith had previously explored, dominated by the British Hudson's Bay Company at Fort Vancouver on the Columbia River.{{sfn|Philbrick|2004}} The federally-funded overland exploration of the West that Smith had requested in 1831 took place starting in 1842 commanded by Lieutenant [[John C. Frémont]] under President [[John Tyler]] and President [[James K. Polk]]. It was Frémont's first two documented and published explorations of the West during the 1840s that opened the West to American expansion.  Frémont was popularly known as the ''Pathfinder'' until the late 19th century, while Smith's life and reputation were nearly forgotten by his countrymen. In 1846, the disputed joint occupancy of Britain and the United States of the Oregon Country where Smith stayed at Fort Vancouver was ended by the [[Oregon Treaty]]. In 1848, Mexico ceded California (where Smith had twice been arrested by Governor Echeandía) to the United States under the [[Treaty of Guadalupe Hidalgo]], ending the [[Mexican–American War]].{{Citation needed|date=January 2023}}
