Which states are consistently included in the region where the Cayuse War took place?
Cayuse War The Cayuse War was an armed conflict that took place in the Northwestern United States from 1847 to 1855 between the Cayuse people of the region and the United States Government and local American settlers. Caused in part by the influx of disease and settlers to the region, the immediate start of the conflict occurred in 1847 when the Whitman Massacre took place at the Whitman Mission near present day Walla Walla, Washington when fourteen people were killed in and around the mission. Over the next few years the Provisional Government of Oregon and later the United States Army battled the Indians east of the Cascades. This was the first of several wars between the Indians and American settlers in that region that would lead to the negotiations between the United States and Indians of the Columbia Plateau, creating a number of Indian reservations.
Tecumseh's War Tecumseh's War or Tecumseh's Rebellion was a conflict between the United States Army and an American Indian confederacy led by the Shawnee leader Tecumseh in the Indiana Territory. Although the war is often considered to have climaxed with William Henry Harrison's victory at the Battle of Tippecanoe in 1811, Tecumseh's War essentially continued into the War of 1812, and is frequently considered a part of that larger struggle. The war lasted for two more years, until the fall of 1813, when Tecumseh, as well as second-in-command Roundhead died fighting Harrison's Army of the Northwest at the Battle of the Thames in Upper Canada, near present-day Chatham, Ontario, and his confederacy disintegrated. Tecumseh's War is viewed by some academic historians as being the final conflict of a longer term military struggle for control of the Great Lakes region of North America, encompassing a number of wars over several generations, referred to as the Sixty Years' War.
