In the years between 1865 - 1900, what ideas and philosophies most influenced the transformation of the United States from isolationism to expansionism? Please keep answers from 3-5 sentences. thank you :)

Well I would say the press and the new form of American idealism for democracy and although not the one introduced by Woodrow Wilsoon we created the American savior freeing from Empires or for our own gain. We weren't the world power but our country was finished with the Civil War and reconstruction. Now was a time of prosperity also we were heavily dependant on other economies and global trade so it's fair to say we needed to grow. Case in point Spanish American War. We wanted to free cuba but didn't really have a reason to go to war. Boom U.S.S Maine suddenly blows up by Spain. Although it is speculative who actually blew it up or was it our country that did it to justify war. I really don't think we'll ever know but it really doesnt

matter. The media made it spread like wildfire and REMEMBER THE MAIN WAS BORN. So we freed other peoples took a bit of land and we grew to be more prosperous. Overall it was oppertunity as much as anything. It would be the Monroe Doctrine as well and now that we actually possessed Power and Spains empire was crumbiling we said freedom. We won and the likes of Roosevelts big stick policy would forever be cemented in history.

the constitution of the united states gave congress the absolute authority over immigration laws
