Washington County began as part of the Cherokee Territory, following an 1817 treaty. The area was next known as Lovely County, and one year later Washington County was created after another Cherokee treaty. The court house was centrally located in the city of Washington, modern-day Fayetteville (renamed to avoid confusion with Washington, Arkansas in South Arkansas). The Lee Creek Valley in southern Washington County contained many of the county's early settlements, including Cane Hill and Evansville. 
Arkansas College and Cane Hill College were both founded in Washington County within a day of each other in 1834, with the University of Arkansas being founded in Fayetteville in 1871. The county witnessed major battles during the American Civil War, including the Battle of Fayetteville, the Battle of Prairie Grove, and the Battle of Cane Hill. The county then was sparsely settled and the residents were divided in their allegiance, since slaves were few, plantations almost nonexistent, and political news came by White River travelers, not from the pro-Confederate southern part of the state.  A Butterfield Overland Mail route was established through the county in 1858, causing more families to settle there. 
The economy of Washington County was based on apples in the late 19th century. A mixture of wet weather, altitude, and loamy soils provided a good environment for apple orchards.  First planted in areas around Lincoln, Evansville, and Cane Hill in the 1830s, apple orchards began all across the county. The United States Census reported a crop of 614,924 bushels of apples produced by the county in 1900, the highest in the state. Several varieties of apple were discovered in the area including Shannon Pippin, Wilson June, and most notably the Arkansas Black.  The Ben Davis became the apple of choice in the area for sale and shipment across the region. Corn became the dominant crop, outselling apples by almost $500,000 in 1900. 
Arkansas Industrial University was founded in the growing community of Fayetteville in 1871 after William McIlroy a donated farmland for the site. The university changed its name in 1899 to the University of Arkansas.  Railroads came to Washington County after the St. Louis – San Francisco Railway (Frisco) decided to build a line to Texas through Fort Smith. Two possible routes were proposed, one passing through Prairie Grove, the other through Fayetteville. Many Fayetteville residents and farmers sold or donated land for the right of way to influence the choice. They were successful and in 1881 the first passenger train arrived at Fayetteville.  The county continued to grow with more churches and schools after the railroad's completion.  Rural parts of the county began losing population in the 1920s during the Great Depression, when high taxes forcing residents to move to Fayetteville or west to Oklahoma. The rural areas later became the Ozark National Forest and Devil's Den State Park. 
According to the U.S. Census Bureau, the county has a total area of 952 square miles (2,470 km2), of which 942 square miles (2,440 km2) is land and 10 square miles (26 km2) (1.1%) is water.  It is the fourth-largest county by area in Arkansas. The county is in the Boston Mountains, a subdivision of the Ozark Mountains. Devil's Den State Park in southern Washington County is known for its picturesque views and mountain vistas.  Washington County also contains Lake Wedington, located in scenic country west of Fayetteville on Wedington Drive.
Washington County sits on a basement of Precambrian granite and rhyolite, as most of the continental interior of the United States does.  Much of the county's geologic history must be inferred from nearby Oklahoma and Missouri research, due to the steepness of the more recently formed mountains that did not form in the neighboring states. This igneous material was eroded until the Paleozoic, when oceans covered the now-low-lying area.  These oceans came and retreated for 300 million years, depositing various different sedements during that time. This created fossiliferous limestone and ripple marked- sandstone, both present throughout the north part of the county as evidence of ancient oceans. 
Sediments were deposited from the Devonian, Mississippian, and Pennsylvanian periods. During this deposition period, the county had a climate similar to that of the present-day Bahamas, as the equator was north of Washington County.  The Devonian brought mostly shales, the Mississippian brought the limestones and chert visible in the bluffs. This chert is present throughout most of the county. The county is also home to the Boone Formation (red soils), white limestones, the Wedington Sandstone, the Bastesville Sandstone, the Pitkin formation (ocean-fossil limestone), and the Fayetteville Shale.
Today, Washington County consists of two main formations, the Boston Mountains and the Springfield Plateau. During the late Pennsylvanian, sediments were deposited on top of the Springfield Plateau. The area was uplifted during the Ouachita orogeny and subsequent erosion formed the rugged Boston Mountains. Erosion of these sediments causes the Boston Mountains to be carved steeply in the south, while in the north of the county, the Boston Mountain sediments are almost entirely eroded, exposing the older rocks of the Springfield Plateau.

The county government is a constitutional body granted specific powers by the Constitution of Arkansas and the Arkansas Code. The quorum court is the legislative branch of the county government and controls all spending and revenue collection. Representatives are called justices of the peace and are elected from county districts every even-numbered year. The number of districts in a county vary from nine to fifteen, and district boundaries are drawn by the county election commission. The Washington County Quorum Court has fifteen members. Presiding over quorum court meetings is the county judge, who serves as the chief operating officer of the county. The county judge is elected at-large and does not vote in quorum court business, although capable of vetoing quorum court decisions.  
There are nine school districts in the county. 
- Elkins School District 
- Farmington School District 
- Fayetteville School District 
- Greenland School District 
- Haas Hall Academy 
- Lincoln School District 
- Prairie Grove School District

The University of Arkansas at Fayetteville was founded in 1871 on the site of a hilltop farm that overlooked the Ozark Mountains, giving it the nickname "The Hill".  The University of Arkansas is in Fayetteville, in Washington County. Historically, Cane Hill College in Canehill was the first college in Arkansas, prior to the University of Arkansas's founding in 1871. Canehill probably influenced the placing the University of Arkansas Washington County, since the history of education in the county was a major factor in the decision.
Townships in Arkansas are the divisions of a county. Each township includes unincorporated areas and some may have incorporated towns or cities within part of their space. Townships have limited purposes in modern times. However, they are of value for historical purposes in terms of genealogical research. Each town or city is within one or more townships in an Arkansas county based on census maps. The townships of Washington County are listed below. In Washington County, each incorporated town/city is at least partially located within its namesake township.

Washington County has contained the Ozark Trail, Trail of Tears, and the Butterfield Overland Mail route. Today, Interstate 49 serves as the county's main thoroughfare, and connects the University of Arkansas with Fort Smith and Interstate 40 to the south and other NWA cities to the north. Future plans call for Interstate 49 to be extended to ultimately connect New Orleans, Louisiana with Kansas City, Missouri through Washington County.
The Arkansas Department of Health is responsible for the regulation and oversight of public water systems throughout the state. Washington County contains twelve community water systems, including two of the largest distribution systems in the state: the City of Fayetteville (retail population served of 94,000)  and Springdale Water Utilities (SWU, 87,618)  Both water systems purchase all potable water from Beaver Water District. Many of the smaller cities in Washington County purchase water from Fayetteville, SWU, Benton-Washington Regional Public Water Authority (PWA, colloquially "Two-Ton") or Washington Water Authority (WWA), including Elkins, Lincoln, Tontitown, West Fork, and Winslow.
