==History== The Nez Perce trail existed in the area before history was recorded, and the first written record of caucasians passing through the area were Lewis and Clark in 1805. Captain Benjamin Bonneville also passed through the future site of the town while he was surveying for the US government in 1834. In 1860, an Irish settler named Parson Quinn settled just east of present-day Pomeroy, and lived there for the next 40 years. Rancher Joseph M.

Pomeroy was officially incorporated on February 3, 1886. The town has been the seat of Garfield County since 1882, despite fierce competition in the 1880s with neighboring towns Pataha and Asotin. The county was split in October 1883, and the city of Asotin was named the county seat of the new Asotin County, Washington, leaving the debate about Pomeroy's status as county seat for Garfield County to continue.<ref>{{Cite web |title=Milestones for Washington State History — Part 2: 1851 to 1900 |url=https://www.historylink.org/File/5380}}</ref> The debate continued through both houses of the Washington Territorial Legislature in for the remainder of 1883 to Governor William A.

Despite a city ordinance which mandated fire-proof materials for downtown buildings after fires in 1890 and 1898, on July 18, 1900 a blaze destroyed half of the small town's business district. The recovery took two years as the destroyed buildings were rebuilt using brick which led to a building boom for the small community.<ref>{{Cite web|url=http://historylink.org/index.cfm?DisplayPage=output.cfm&file_id=7694|title = Fire destroys nearly half the business district of downtown Pomeroy on July 18, 1900}}</ref> In 1912, the city voted to outlaw the manufacture or sale of alcohol.
