Boundary County is the northernmost county in the state of Idaho. It's located in the United States. In 2020, about 12,056 people lived there. The main city and county seat is Bonners Ferry.

Boundary County was created on January 23, 1915. It got its name because it shares a border with Canada. This makes it the only county in Idaho with an international border. It's also one of only three counties in the whole United States that borders two states and a foreign country.

History of Boundary County

Boundary County was formed in 1915 from Bonner County. It was named "Boundary County" because it sits on the border of Canada, Washington, and Montana.

The area began to be settled when Bonners Ferry was started in 1864. This town was built on the Kootenai River. For a while, settlement was mostly just around the ferry. By 1890, more people started to arrive. The town of Bonners Ferry was officially established in 1893.

At first, there were only a few small farms and mining spots. But the timber industry (logging) started to grow. By 1900, other areas like Boulder (now Kootenai) and Naples also began to develop.
