Overview
The Provisional Legislature of Oregon was the legislative branch of the Provisional Government of Oregon, an elected settler government created in the Oregon Country before the United States formally established sovereignty over the region. It operated from 1843 through early 1849, primarily in and around Oregon City, and was the first locally organized legislature to exercise broad governmental authority over the American settler population in the Willamette Valley and adjacent districts. The institution emerged from the political movement that organized at Champoeg in May 1843. On May 2, settlers voted narrowly to create a provisional government, and a nine-person committee subsequently drafted the Organic Laws of Oregon. Ratified on July 5, 1843, those laws established a government with executive, judicial, and legislative components. The legislative branch was initially called the Legislative Committee. Its nine elected members were apportioned among four districts and were expected to meet in June and December. The committee's constitutional model drew substantially on the governmental arrangements of Iowa Territory. During its six-year existence, the legislature developed from a small committee into a more formal representative body. The 1845 revision of the Organic Laws renamed it the House of Representatives, increased its authorized size to between 13 and 61 members, and expanded its powers. These included taxation, district organization, creation of lower courts and post offices, militia administration, regulation of trade and liquor, legislation concerning public welfare, and impeachment of civil officers. Oregon City was designated the official capital, and income and property taxes replaced an earlier subscription-based financing system. The legislature addressed practical problems faced by a remote settler government. It incorporated Oregon City and other local institutions, authorized improvements such as the Barlow Road, supported the Oregon Institute and Multnomah Circulating Library, regulated liquor, and established standards for pilots navigating the mouth of the Columbia River. It also adopted exclusionary and racially discriminatory measures, including the 1844 Lash Law, which sought to prevent Black people from residing in the territory and imposed corporal punishment on those who refused to leave. Other measures regulated relations and commerce with Native peoples, including restrictions on the sale of firearms and supplies. The body also became a central institution during the Cayuse War. After receiving news of the Whitman massacre in December 1847, legislators authorized and supported military action. An initial force was sent toward The Dalles under Henry A. G. Lee, followed by a larger expedition commanded by Cornelius Gilliam. The legislature's actions reflected both the insecurity of the provisional government and the severe consequences of settler-Native conflict. The final organized session met from February 5 to February 16, 1849. It authorized the production of gold coins known as Beaver Coins, but the measure was soon nullified by Territorial Governor Joseph Lane after the United States territorial government assumed authority. Lane regarded the coinage law as incompatible with the federal government's constitutional power over money. The provisional government was otherwise succeeded by the government of Oregon Territory, created by Congress in 1848. Many former provisional legislators, including David Hill and Asa Lovejoy, continued in public life, and some participated in the new territorial legislature. The institution therefore represents an important transitional stage between settler self-government and formal United States territorial administration.
History
The Provisional Legislature of Oregon developed from the settler government organized in the Oregon Country in 1843. Following the Champoeg vote of May 2, a nine-person committee met in Oregon City in May and June to draft the Organic Laws of Oregon. The laws, ratified on July 5, created a provisional government and authorized a nine-member Legislative Committee. Members were elected from four districts, with sessions expected in June and December. The legislature's early work focused on establishing basic governmental machinery. Committees dealt with land claims, appropriations, military affairs, the judiciary, and district boundaries. The 1844 sessions took place in private homes in Oregon City. That year the body adopted the Lash Law, an exclusionary measure directed at Black residents and migrants. The law illustrates how the provisional government combined representative institutions with discriminatory racial policy. A major institutional reorganization occurred in 1845. The revised Organic Laws renamed the legislative branch the House of Representatives, provided for at least 13 and as many as 61 representatives, and expanded legislative authority. The legislature could levy taxes, organize districts, create courts and post offices, regulate liquor and trade, administer the militia, declare war, and impeach civil officers. Oregon City became the official capital. The legislature also authorized the Barlow Road, incorporated Oregon City, and supported educational and cultural institutions. The 1846 session was comparatively restrained because the United States and Great Britain were moving toward a settlement of their competing claims to the Oregon Country. Its notable measures included pilotage rules for the Columbia River. The 1847 session changed direction after legislators learned of the Whitman massacre. The provisional government cooperated with the Hudson's Bay Company and organized military forces against the Cayuse. The legislature also created Benton District from part of Polk District. The last phase was disrupted by migration to California during the gold rush. A December 1848 session did not formally organize because too many representatives were absent. A final organized session met in February 1849 and repealed a restriction on supplying firearms and related goods to Native Americans. It also authorized the minting of gold coins, the Beaver Coins. After the creation of Oregon Territory and the arrival of Governor Joseph Lane, the coinage law was invalidated and the coins were withdrawn because Congress held constitutional authority over coinage. The provisional legislature ended when territorial government replaced the provisional system. Its institutional legacy continued through former members who entered territorial politics and through the laws that remained in force, apart from the coinage authorization.
