Deng is remembered primarily for the economic reforms he initiated while paramount leader of the People's Republic of China, which pivoted China towards a market economy, led to high economic growth, increased standards of living of hundreds of millions, expanded personal and cultural freedoms, and substantially integrated the country into the world economy. More people were lifted out of poverty during his leadership than during any other time in human history, attributed largely to his reforms. For this reason, some have suggested that Deng should have been awarded the Nobel Peace Prize. Deng is also credited with reducing the cult of Mao Zedong and with bringing an end to the chaotic era of the Cultural Revolution. Furthermore, his strong-handed tactics have been credited with keeping the People's Republic of China unified, in contrast to the other major Communist power of the time, the Soviet Union, which collapsed in 1991.
