Carlsen became World Chess Champion in 2013 by defeating Viswanathan Anand. In the following year, he retained his title against Anand, and won both the 2014 World Rapid Championship and World Blitz Championship, thus becoming the first player to hold all three titles simultaneously, a feat he repeated in 2019.
