The Chicago White Sox is a professional baseball team founded in 1893 as the Sioux City , Iowa franchise in the minor Western League. Currently the team is based in Chicago, Ilinois and is positioned in the Central Division of the American League. The team was launched by Charles Comiskey who played with the St. Louis Browns in the 1880s. The Sioux City Cornhuskers took home the victory in 1894. After moving to St. Paul , Minnesota in 1895, the club adopted the name St. Paul . When the Western League became the American League in 1900 the St. Paul moved to Chicago to contend directly with the National League club in that city. After establishing themselves in Chicago , the team acquired the moniker "White Stockings", which was incidentally the original name of the Chicago Cubs. The new team procured number of star players from the NL. The club won its first AL championship in 1901 due to the disciplined management of Clark Griffith who was also their leading pitcher. The team recorded the "Hitless Wonders" in 1906 for having the lowest team batting average in the American League. At that time the team was led by Walsh, Doc White and Nick Altrock. In the following decade, though the White Sox contended with full determination but did not bring home the coveted pennant until 1917. The club rebounded in 1919 and won the championship. This made them eligible to participate in the World Series. There they faced the powerful Cincinnati Reds and threw them out of the action. This was also the season of notorious Black Sox scandal. The eight White Sox players were expelled from the professional baseball including Cicotte and Jackson for fixing the World Series.

For the next four decades the White Sox did not appear in the World Series. The club utterly needed a team built on pitching and defense. In 1959 though the team lead the league and produced runs through speed and cunning they lost the World Series to the Los Angeles Dodgers. The team of 80s was led by catcher Carlton Fisk, outfielder Harold Baines, outfielder Ron Kittle, pitchers Lamarr Hoyt and Richard Dotson. They were managed by Tony La Russa also won the Manager of the Year award. Due to their horrible method of playing the team earned the phrase, "Winning Ugly". Though they had score great runs in the regular season playoffs but were unable to sustain themselves in the postseason playoffs as they lost to Baltimore 3 games to one in the AL Championship Series. In 1991, the club moved to their new official stadium viz. New Comiskey Park , now known as U.S. Cellular Field. From time to time renovations have been carried out to make the park more fan friendly.

In 1990s the White Sox changed their jersey color to black. The trend instantaneously jumped to the top of the league in merchandise sales. The team of 1990s was led by pitcher Jack McDowell and first baseman Frank Thomas. The team reached the American League Championship Series in 1993 and the American League Division Series in 2000. In 1997, the authorities traded veteran pitchers Wilson Alvarez, Danny Darwin and Roberto Hernandez to the San Francisco Giants in exchange for 6 minor leaguers. This trade came to be known as the "White Flag Trade" by the Chicago Newspapers. This trade was indeed a setback for the White Sox fans. In 2000, the Sox had one of the finest team since the 1983 club. Despite of having an average pitching staff lead by Mike Sirotka, the club won various regular season playoffs but were not fortunate enough to carry any success over into the postsesaon, getting swept by the wild-card Seattle Mariners in 3 games in the AL Division Series round. The Chicago White Sox steered in a new era with the procurement of Ozzie Guillén, who known for his passion and high spirits.

The Chicago White Sox share a great professional rivalry with their cross-town rival the Chicago Cubs. Moreover with the introduction of inter-league play has deepened the rivalry.
