History of Jefferson County

How Jefferson County Was Formed

Jefferson County was officially started on June 11, 1792. It was created by William Blount, who was the governor of the Southwest Territory at that time. Before this, the area was part of Caswell County during a time when a short-lived state called the State of Franklin existed (from 1784 to 1789). The county seat, Dandridge, was settled even earlier, in 1783.

Jefferson County During the Civil War

Before the American Civil War began, most people in Jefferson County, like many in eastern Tennessee, did not want to leave the United States. On June 8, 1861, Tennessee voted on whether to separate from the U.S. Voters in Jefferson County said "no" to leaving by a large number: 1,987 against, and only 603 for.

During the war, a railroad bridge at Strawberry Plains was part of a plan to burn bridges in East Tennessee. This led to disagreements among people in the county. Some men from Jefferson County joined the Union Army, while others joined the Confederate Army.

A Sad Event on I-40

On October 2, 2013, a serious accident happened on I-40 in Jefferson County. It was near where I-40 and I-81 meet. A church bus, a large truck, and an SUV were involved. Officials found that a tire on the church bus blew out. This caused the bus to move into traffic coming the other way. It hit the SUV and then crashed into the semi-truck, which caught fire. Sadly, 8 people died and 14 were hurt in this accident.
