Age of Imperialism: Chapter 6: Anti-Imperialist League

So obviously not everyone in our nation was in total favor of our expansion. In fact, many very famous and wealthy Americans wanted to follow Washington's directions in his farewell speech and steer clear of engaging ourselves in foreign countries. The Anti-Imperialist League was created to try to prevent this from happening. But what was the Anti-Imperialist League? Who were they? And what influence did they have in the matter? Lets see...
First of all, the Anti-Imperialist League was a movement that argued that the U.S. should pull out of the Philippines. They believed that if we didn't, two things would happen, either Americans would corrupt themselves because of the brutal way they'd have to fight this war, or that if McKinley won the war, he wouldn't be able to extend constitutional rights to the Filipinos, that the American constitution was meant only for certain races and couldn't extend beyond our continent.
Who was a part of this movement though? Politicians, academics, and authors were all involved and believed strongly about it. Charles Francis Adams Jr, Jane Adams, Edward Atkinson, Ambrose Bierce, Andrew Carnegie, Samuel Clemens (AKA Mark Twain), and Grover Cleveland were just a few well known people a part of the Anti-Imperialist League. The league was already having trouble letting African-Americans in and they thought that adding any more races to our constitution, it would be detrimental.
So with all these very influential people putting their hearts into this movement, did they even make a difference? The league believed that they were trying to save the American way and also believed that McKinley was just destroying everything. In ways they were very influential and in other ways, they were just crazy.
