History of Washington County
Early Settlements and the Washington District
Washington County's story began in the early 1770s. This was when the Watauga settlements were formed. They were near what is now Elizabethton. When the Revolutionary War started in 1776, the Watauga settlers created the "Washington District." A group called a "committee of safety" governed it. North Carolina first did not accept these settlements. But it later added the district after the settlers stopped attacks from the Cherokee people. The Washington District included all of what is now Tennessee. It became Washington County in 1777.
The State of Franklin and North Carolina
From 1777 to 1784, North Carolina had control over the county. But the people living there felt North Carolina did not help them much. So, in 1784, they formed their own area called the State of Franklin. This was an early try to create a new state, before Kentucky and Vermont joined the United States. However, the State of Franklin did not last. The county returned to North Carolina's control in 1788.
Becoming Part of Tennessee
In 1790, the area became part of the Southwest Territory. Then, in 1796, it joined the United States as the 16th state, Tennessee. Jonesborough, the county seat, is the oldest town in Tennessee. Many of its buildings have been fixed up. They show what life was like between 1790 and 1870.
During the American Civil War, people in Washington County had mixed feelings. Some supported the Union, and some supported the Southern states that wanted to leave. In 1861, Washington County voted to stay in the Union. One of the bridges that was attacked by Union supporters in 1861 was near Watauga. Landon Carter Haynes, a senator for the Confederate side, was from Washington County.
Johnson City, first known as Johnson's Depot, was a big railway hub. It connected the region for moving goods and people. It was home to two important railroads. One was the Carolina, Clinchfield, and Ohio (Clinchfield Railroad). Building it needed 17 tunnels to be dug. The other was the East Tennessee and Western North Carolina Railroad (Tweetsie). Today, many historic railroad buildings in Johnson City are being restored. They show the city's important past as a railway center.
