True, you are correct. Though it could be attributed to the author as a smaller mistake, as Franz was assassinated by a Serbian nationalist. I am more confused to how the US's reconstruction had anything to do with setting the stage for World War 1.
> For just as 1866 guaranteed a militarily and culturally strong Germany which would wear down Britain, France, and Italy to a near breaking point in World War I, it also guaranteed a truly united United States, with a society that held the majority view that democracy and equality were worth fighting for – and which would intervene to defeat Germany just in the nick of time.
Nothing in the piece supports this statement, and I find this pretty hard to agree with. The first part of the article is a rehash of known facts and history. The last few paragraphs are, from what I can tell, irrelevant to the overall theme as well as thinly-veiled glorification of the United States Civil Rights Act.
