Why Francis Fukuyama's thesis different from Karl Marx's concept of end of history?

Francis Fukuyama's thesis of the end of history suggests that liberal democracy and free-market capitalism have become the final form of human government and economy, marking the end of ideological evolution. In contrast, Karl Marx's concept of the end of history revolves around the idea that capitalism will eventually be replaced by communism, leading to a classless society and the end of historical development. Fukuyama's thesis is more about the triumph of liberal democracy, while Marx's concept emphasizes the transition from capitalism to communism.
