The era of the treaty wars in Washington Territory lasted from 1855-1856. Territorial Governor and Superintendent of Indian Affairs Isaac Stevens (1818-1862) ordered the building of forts and blockhouses to provide settlers safe refuge. Blockhouses were erected in settler communities around the territory. Only a few had stockades and minimal housing. Most were constructed by the militia, the Washington Territorial Volunteers. The U.S. Army built a few forts and individuals created blockhouses or defenses for themselves and neighbors. These defenses lasted only a short time. The threat was over by the end of 1856 with treaties signed in which Indians gave up huge land areas. With the 1856 treaties most of the forts were abandoned. A few survive today to recall that era. 

Hostilities of the Indian Wars

The hostilities comprised the Yakima Wars in the eastern Washington Territory and the Puget Sound War in the west. Governor Stevens ordered Washington Territorial Volunteers to build forts for settler protection. The forts would be a refuge that they could retreat to during Indians attacks. The term "fort" for many of these shelters is misleading as most were only a blockhouse. Some had stockade fences and hut housing. They lacked barracks, mess halls, parade grounds, and other physical fort features. In addition to the Washington Territorial Volunteer forts, the U.S. Army constructed posts to support operations against the Indians. Also, in some cases the local settler community or individual families erected blockhouse defenses. Unnamed locally built blockhouses went up in many communities. There were approximately 47 named blockhouses -- forts constructed during 1855-1856.

By the end of 1856 treaties had been signed in which the Indians gave up large areas of land to bring about peace. With the treaties the forts and blockhouses were abandoned in 1856. Over the years they disappeared, leaving very few surviving examples.

This fort and blockhouse list does not include trading posts called forts or camps and encampments.
