<p>Shoshone County is the location of the Silver Valley, which is one of the richest sources of silver in the United States. It was also the site of tension between miners and mining companies in the late 1890s, which resulted in several strikes and military intervention. The conflict eventually culminated in the assassination of former Idaho Governor Frank Steunenberg in 1905.</p>
