Answer
**Answer: Communism** Communism, as an ideology rooted in collective ownership and classless society, faces challenges from Fukuyama's concept of the "End of History." Fukuyama argues that liberal democracy represents the endpoint of humanity's sociopolitical evolution, suggesting the eventual triumph of individual liberty and market-oriented economies over alternative systems like communism. This challenges the core tenets of communism and its vision for a revolutionary transformation of society.
