The St. Louis Cardinals, a professional baseball franchise based in St. Louis, Missouri, compete in the National League (NL) of Major League Baseball (MLB). Founded in 1882 as a charter member of the American Association (AA), the team was originally named the Brown Stockings before it was shortened to Browns the next season. The team moved to the National League in 1892 when the AA folded. The club changed its name to the Perfectos for one season in 1899 and adopted the Cardinals name in 1900. The St. Louis Cardinals are tied with the Cincinnati Reds and Pittsburgh Pirates as the third-oldest continuously-operated baseball team. In that time, the team has won 19 National League pennants and 11 World Series championships (most in the National League and second only to the New York Yankees, who have won 27). They also won four American Association pennants and one pre-World Series championship that Major League Baseball does not consider official. The Cardinals had six periods of continued success during their history. The first period occurred during the 1880s when the team won four consecutive American Association pennants from 1885–1888 while known as the Browns. The Cardinals next found success from 1926–1934 when they played in five World Series, winning three. During World War II the Cardinals won four NL pennants in five years from 1942–1946, including three World Series championships. During the 1960s the Cardinals won two World Series and played in another. In the 1980s the Cardinals played in three World Series, winning in 1982. Most recently, the Cardinals have made the playoffs nine times, winning seven NL Central titles and qualifying as a wild-card entrant in 2001, 2011 and 2012, winning the World Series in 2006 and 2011. The only extended period of failure the Cardinals have experienced began when they joined the National League in 1892. The Cardinals played only five winning seasons in 30 years while finishing last seven times from their entrance to the NL until 1921. However, the Cardinals have remarkably avoided such failure since then as they have not finished in last place in the National League since 1918, by far the longest streak in the NL. Like the Yankees and Dodgers, the Cardinals have never lost 100 games in a season since World War I. The Cardinals failed to reach the World Series in the 1950s, 1970s, and 1990s, but were regularly a competitive
