The area of the lower
Willamette River has been inhabited for thousands of years, including by the
Multnomah band of
Chinookan peoples long before European contact, as evidenced by the nearby Cathlapotle village, just downstream. Multnomah County (the 13th in
Oregon Territory) was created on December 22, 1854, formed out of two other Oregon counties – the eastern part of
Washington County and the northern part of
Clackamas County. Its creation was a result of a petition earlier that year by businessmen in Portland complaining of the inconvenient location of the Washington County seat in
Hillsboro and of the share of Portland
tax revenues leaving the city to support Washington County farmers. County commissioners met for the first time on January 17, 1855. The county is named after the
Chinookan word for the "lower river",
multnomah,
matlnomaq, or
máɬnumax̣ being interpretive English spellings of the same word. In Chinook jargon,
Ne-matlnomaq, means the "place of matlnomaq" or the (singular)
Ne-matlnomag, "the lower river", from the Oregon City Falls toward the Columbia River. Alternatively, Chinookan
máɬnumax̣ (also
nímaɬnumax̣) "those toward water" (or "toward the Columbia River", known in Chinookan as
ímaɬ or
wímaɬ, "the great water"). Explorer
William Clark wrote in his journal: "I entered this river...called Multnomah...from a nation who reside on Wappato Island, a little below the enterence" (quoted from
Willamette Landings by H.M. Corning).(see:Portland Basin Chinookan Villages in the early 1800s, Boyd and Zenk,) Although Clark refers to the Willamette River as Multnomah, he may not have understood the meaning. Simply put,
Multnomah ("down river" or "toward the great water") is the shortened form of
nematlnomaq/nímaɬnumax̣. In 1924, the county's three commissioners were indicted and recalled by voters "in response to 'gross irregularities' in the award of contracts for construction of the
Burnside and
Ross Island bridges"; since all three had been supported by the
Ku Klux Klan, their recall also helped reduce that organization's influence in the city.
Vanport, built north of Portland in 1943 to house workers for
Kaiser Shipyards, was destroyed by a flood five years later. In 1968, the
Oregon Legislative Assembly referred a bill,
Ballot Measure 5, to voters that would amend the state constitution to allow for
consolidated city-county governments when their populations are over 300,000. The 1968 voters' pamphlet noted that Multnomah County would be the only county in Oregon affected by the measure and voters approved the referendum in the 1968 general election. Since the approval of Measure 5 in 1968, an
initiative to merge the county with
Portland has been considered and placed on the county ballot several times.
Since 2000 In the
2000 presidential election, Multnomah county played a decisive role in determining the winner of the state's
electoral votes.
Al Gore carried the county by 104,764 votes, enough to offset the 97,999 vote advantage that
George W. Bush had earned among Oregon's 35 other counties. The Democratic tilt was repeated in 2004, when John Kerry won by 161,146 votes, and in 2008, when Barack Obama won by 204,525 votes. In February 2001, the Multnomah County Board of Commissioners unanimously accepted the recommendation of the
Library Advisory Board and authorized the library to enter into a lawsuit to stop the
Children's Internet Protection Act. Faced with decreasing government revenues due to a recession in the local economy, voters approved a three-year local income tax (Measure 26–48) on May 20, 2003, to prevent further cuts in schools, police protection, and social services. After that, though, Linn and the three commissioners developed a public feud, with the latter becoming known as the "mean girls". The county government has also faced significant budget issues, including not being able to open the
Wapato Corrections Facility since it was built in 2003. ==Geography==
