What were some life-changing historical events that happened in the same year but in different parts of the world?

This is inspired by an old Reddit post where the author wrote how bizarre it is that the Wright brothers flew their first powered aircraft on December 17, 1903, and the next day, the same newspaper published an article of a war between Japan and Russia and the assassination of the king and queen of Serbia.<br><br>So I am wondering, are there other historical events like this?
