Francis Fukuyama, in an article in 1989 called "The End of History?", argues that history has come to completion. This seems like an absurd argument, but you have to understand what "history" means in this case. Fukuyama is using a Hegelian sense of the term, mediated by Alexander Kojeve. History refers to the conflict in society between opposing ideological positions. It's not that nothing more will happen, but rather that history as driven by the conflict of ideologies is over. Why? Because one of these "ideologies" won - Western liberalism.
