A Clash of Nations: In 1864, vast herds of buffalo roamed the northern short-grass prairie and numerous Native American nations lived on both sides of the adjacent Continental Divide.  Lewis & Clark had come and gone, and so had most of the fur trappers and mountain men.  The land that would become Montana was mostly still the wild and untrammeled landscape it had been for millennia.

That all changed in  single year-1864-because of gold, the Civil War, and the relentless push of white Americans into Indian lands.  By the end of that pivotal year in the history of Montana-and in the history of the American West-Montana was the newest United States territory.
