Oregon boundary dispute
The Oregon boundary dispute or the Oregon Question was a 19th-century territorial dispute over the political division of the Pacific Northwest of North America between several nations that had competing territorial and commercial aspirations in the region.
Expansionist competition into the region began in the 18th century, with participants including the Russian Empire, Great Britain, Spain, and the United States. After the War of 1812, the Oregon dispute took on increased importance for diplomatic relations between the British Empire and the fledgling American republic. In the mid-1820s, the Russians signed the Russo-American Treaty of 1824 and the Russo-British Treaty of 1825, and the Spanish signed the Adams–Onís Treaty of 1819, by which Russia and Spain formally withdrew their respective territorial claims in the region, and the British and the Americans acquired residual territorial rights in the disputed area. But the question of sovereignty over a portion of the North American Pacific coast was still contested between the United Kingdom and the United States. The disputed area was defined as the region west of the Continental Divide of the Americas, north of Mexico's Alta California border of 42nd parallel north, and south of Russian America at parallel 54°40′ north. The British generally called this region the Columbia District and the Americans generally called it Oregon Country.
During the 1844 United States presidential election campaign, the Democratic Party proposed ending the Oregon Question by annexing the entire area. The U.S. Whig Party, in contrast, evinced no interest in the question – due, some scholars have claimed, to the Whig view that it was unimportant compared to other domestic problems. The Democratic candidate, James K. Polk, invoked the popular theme of manifest destiny and appealed to voters' expansionist sentiments in pressing for annexation, and defeated the Whig candidate, Henry Clay. Polk then sent the British government an offer to agree on a partition along the 49th parallel.
However, the resulting negotiations soon faltered: the British still pressed for a border along the Columbia River. Tensions grew as American expansionists, such as Senator Edward A. Hannegan of Indiana and Representative Leonard Henly Sims of Missouri, urged Polk to annex the entire Pacific Northwest all the way to the 54°40′ parallel north. These tensions gave rise to slogans such as "Fifty-four Forty or Fight!" At the same time, U.S. relations with the Centralist Republic of Mexico were rapidly deteriorating as a result of the recent U.S. annexation of Texas. This gave rise to a concern that the U.S. might have to fight two wars on two fronts at the same time. Thus, just before the outbreak of the Mexican–American War, Polk retreated to his earlier position, calling for the Oregon border to run along the 49th parallel.
The 1846 Oregon Treaty established the border between British North America and the United States along the 49th parallel until the Strait of Georgia, where the marine boundary curved south to exclude Vancouver Island and the Gulf Islands from the United States. As a result, a small portion of the Tsawwassen Peninsula, Point Roberts, became an exclave of the United States. Vague wording in the treaty left the ownership of the San Juan Islands in doubt, as the division was to follow "through the middle of the said channel" to the Strait of Juan de Fuca. During the so-called Pig War, both nations agreed to a joint military occupation of the islands. Kaiser Wilhelm I of the German Empire was selected as an arbitrator to end the dispute, with a three-man commission ruling in favor of the United States in 1872. There the Haro Strait became the borderline, rather than the British-favored Rosario Strait. The border established by the Oregon Treaty and finalized by the arbitration in 1872 remains the boundary between the United States and Canada in the Pacific Northwest.
Background
The Oregon Question originated in the 18th century during the early European or American exploration of the Pacific Northwest. Various empires began to consider the area suitable for colonial expansion, including the Americans, Russians, Spanish and British. Naval captains such as the Spanish Juan José Pérez Hernández, British George Vancouver and American Robert Gray gave defining regional water formations like the Columbia River and the Puget Sound their modern names and charted them in the 1790s. Overland explorations were commenced by the British Alexander Mackenzie in 1792 and later followed by the American Lewis and Clark expedition, which reached the mouth of the Columbia River in 1805. These explorers often claimed in the name of their respective governments sovereignty over the Northwest Coast. The knowledge of fur-bearing animal populations like the California sea lion, North American beaver and the Northern fur seal were used to create an economic network called the maritime fur trade. The fur trade would remain the main economic interest that drew Euro-Americans to the Pacific Northwest for decades. Merchants exchanged goods for fur pelts along the coast with indigenous nations such as the Chinookan people, the Aleuts and the Nuu-chah-nulth.Image:Columbiarivermap.png|thumb|upright=1.6|Map of the Columbia River and its tributaries, showing modern political boundaries and cities.
Spanish colonization
A series of expeditions to the Pacific Northwest were financed by the Spanish to strengthen their claims to the region. Creating a colony called Santa Cruz de Nuca on Vancouver Island, the Spanish were the first European colonisers of the Pacific Northwest outside Russian America to the north. A period of tensions with the United Kingdom, called the Nootka Crisis, arose after the Spanish seized a British vessel. However the three Nootka Conventions averted conflict, with both countries agreeing to protect their mutual access to Friendly Cove against outside powers. While the Spanish colony was abandoned, a border delineating the northern reaches of New Spain was not included. Despite the Nootka Conventions still allowing the Spanish to establish colonies in the region, no more attempts were made as other geopolitical and domestic matters drew the attention of the authorities. With the Adams–Onís Treaty of 1819, the Spanish formally withdrew all formal claims to lands north of the 42° north.Russian interest
The Imperial Russian government established the Russian-American Company in 1799, a monopoly among Russian subjects for fur trading operations in Russian America with the Ukase of 1799. In part from the growing Russian activities to the north, the Spanish created the Catholic Missions to create colonies in Alta California. Plans for creating Russian colonies in what became the modern American states of Washington and Oregon were formulated by Nikolai Rezanov. He aimed to relocate the primary colony of Russian America to the entrance of the Columbia River, but was unable to enter the river in 1806 and the plan was abandoned.In 1808 Alexander Andreyevich Baranov sent the Nikolai, with the captain "ordered to explore the coast south of Vancouver Island, barter with the natives for sea otter pelts, and if possible discover a site for a permanent Russian post in the Oregon Country." The ship wrecked on the Olympic Peninsula and the surviving crew did not return to New Archangel for two years. The failure of the vessel to find a suitable location led to the Russians to not consider much of the Northwest coast worth colonizing. Their interest in the Puget Sound and the Columbia River was diverted to Alta California, with Fort Ross soon established.
The Russo-American Treaty of 1824 and the 1825 Treaty of Saint Petersburg with the British formally created the southern border of Russian America at parallel 54°40′ north. Specifically, it was agreed, in the 1824 treaty, that no American settlement would be established on the coast or adjacent island north of 54°40′, and no Russian settlement to the south. The treaty did not make any explicit statements about sovereignty or territorial claims. The 1825 treaty with Britain was more strongly worded and defined the boundary between Russian and British possessions in North America, which ran north from 54°40′ through what is now the Alaska Panhandle to the 141st meridian west, then along that line north to the Arctic Ocean.
