The history of the city of Portland, Oregon, began in 1843 when business partners William Overton and Asa Lovejoy filed to claim land on the west bank of the Willamette River in Oregon Country. In 1845 the name of Portland was chosen for this community by coin toss. February 8, 1851, the city was incorporated. Portland has continued to grow in size and population, with the 2010 Census showing 583,776 residents in the city. Early history The land today occupied by Multnomah County, Oregon, was inhabited for centuries by two bands of Upper Chinook Indians. The Multnomah people settled on and around Sauvie Island and the Cascades Indians settled along the Columbia Gorge. These groups fished and traded along the river and gathered berries, wapato and other root vegetables. The nearby Tualatin Plains provided prime hunting grounds. Eventually, contact with Europeans resulted in the decimation of native tribes by smallpox and malaria. Founding The site of the future city of Portland, Oregon, was known to American, Canadian, and British traders, trappers and settlers of the 1830s and early 1840s as "The Clearing," a small stopping place along the west bank of the Willamette River used by travelers en route between Oregon City and Fort Vancouver. As early as 1840, Massachusetts sea captain John Couch logged an encouraging assessment of the river’s depth adjacent to The Clearing, noting its promise of accommodating large ocean-going vessels, which could not ordinarily travel up-river as far as Oregon City, the largest Oregon settlement at the time. In 1843, Tennessee pioneer William Overton and Boston, Massachusetts lawyer Asa Lovejoy filed a land claim with Oregon's provisional government that encompassed The Clearing and nearby waterfront and timber land. Legend has it that Overton had prior rights to the land but lacked funds, so he agreed to split the claim with Lovejoy, who paid the 25-cent filing fee. Bored with clearing trees and building roads, Overton sold his half of the claim to Francis W. Pettygrove of Portland, Maine, in 1845. When it came time to name their new town, Pettygrove and Lovejoy both had the same idea: to name it after his home town. They flipped a coin to decide, and Pettygrove won. On November 1, 1846, Lovejoy sold his half of the land claim to Benjamin Stark, as well as his half-interest in a herd of cattle for $1,215. Three years later, Pettygrove had lost
