World war one caused multiple changes including setting a new record for the number of deaths seen in the world, it created new divisions( nation-states), forced the US to become a world power, encouraged new independence movements, and had a major influence on the rise of soviet communism and in essence, the rise of Hitler. The world war changed the way political dealings are handled and caused the racial division to continue to grow. Yes, this war solved things at the time but it was putting a bandaid on a bullet wound, in the long run, it caused the world to be more broken than ever. This was a pivotal point in the world that both helped and hurt the human race. The world could never come back from that war and leaves life in the future to the ruins that the shedding of blood has brought us.
It would be the journal written by Christopher Columbus. (even though he didn't actually discover the new world, so he shouldn't get credit for it... but that's how it's taught in history.)
