Before current era (1910–1983)

The history of professional baseball in Charleston, dates back to 1910, and a team known as the Charleston Statesmen of the long-forgotten Class D Virginia Valley League. In 1911, the Statesmen moved to the Class D Mountain State League, and then folded after that year. A new team, the Charleston Senators was formed in 1914 and lasted three seasons in the Class D Ohio State League. In 1931, a new Senators team joined the Class C Mid-Atlantic League as an affiliate of the Cincinnati Reds. This team lasted until 1943. In 1949, the Senators were reformed as a member of the Class A Central League. In 1952, the city was granted a franchise in the Triple-A American Association. At first, this team was affiliated with the Chicago White Sox, then the Detroit Tigers, and finally the Washington Senators. In 1958, the Charleston Senators won the American Association championship. The franchise ceased operations after the 1960 season.

In 1961, the city had no team, but the Triple-A International League San Juan Marlins, affiliated with the St. Louis Cardinals, moved to the city but on May 19 the team was deemed not financially viable. In 1962, the Charleston Indians, affiliated with the Cleveland Indians, moved to the city in the Class-A Eastern League, and in 1963 that league was elevated to Double-A. The team folded after the 1964 season.

Baseball returned to the city in 1971 with the Charleston Charlies of the Triple-A International League. The Charlies played in the International League from 1971 to 1983. The team had previously been the Columbus Jets. The Charlies were affiliated with the Pittsburgh Pirates, Houston Astros, Texas Rangers, and finally the Cleveland Indians. The team won the International League championship in 1973 and 1977. The Charlies left for Maine following the 1983 season, and, after relocating to Moosic, Pennsylvania in 1989, the team is now known as the Scranton/Wilkes-Barre RailRiders.

Today, the Dirty Birds sell nostalgic "throwback" merchandise from the Pittsburgh-affiliated era of the Charlies, which is generally considered the pinnacle of baseball in the city.

Revival era (1987–2020)

In 1987, the city resumed minor league baseball after a three-year absence. The new team was first called the Charleston Wheelers, so named for the city's history of stern- and side-wheeled boats. The Wheelers began as a co-op team, with players from several Major League Baseball franchises including the Los Angeles Dodgers, Detroit Tigers, Chicago White Sox, Chicago Cubs, Philadelphia Phillies, and Atlanta Braves.

In 1988, the franchise became the Chicago Cubs' third full-season Class A franchise (the other two being Peoria in the Midwest League and Winston-Salem in the Carolina League). The only two players on that 1988 squad to reach the Major Leagues were SS Alex Arias and C Matt Walbeck.

The Wheelers won the Class A South Atlantic League championship in 1990, the only league title for the franchise. By that point, they had changed affiliation to the Cincinnati Reds. SAL Northern Division championships followed in 1991 and 1992, with the Wheelers losing the championship series both years.

In late 1993, the Wheelers were purchased from then-owner Dennis Bastien by a conglomerate of local owners led by Charleston businessman Michael Paterno. The team changed its name to the Charleston Alley Cats in 1995 and switched colors from blue and green to red and black. The team was purchased in 2001 by Tom Dickson and Sherrie Myers. In 1998, the team changed affiliation to the Kansas City Royals, again in 2000 to the Toronto Blue Jays, to the Milwaukee Brewers after the 2004 season, joined the Pirates in 2009, and finally the Seattle Mariners in 2018. Prior to the 2005 season, they adopted the West Virginia Power name. To quote the team's announcement following their decision to change the team name:

West Virginia is and will continue to be recognized as one of the leading energy providers for the country. The energy production from coal, natural gas, and hydro-electric sources, combined with the fact that Charleston serves as the center for the state's political and economic powers led us to the name of the team. We felt it was extremely important that the name reflect the entire region and are excited about the tremendous marketing opportunities that will go along with the name.

The Power won the 2007 SAL Northern Division title, but lost in the league championship series to the Columbus Catfish in three straight games.

2021 and beyond

In conjunction with Major League Baseball's reorganization of the minors after the 2020 season, the Mariners opted to discontinue their affiliation with West Virginia, leaving them in need of a new affiliate for 2021.^[5] It was later confirmed that the Power would be dropped from affiliated baseball, with the team stating its intent to continue playing for 2021 and beyond in another league.^[6]

On February 24, 2021, the team announced that it had been sold to a new ownership group led by Andy Shea, also owner of the Power's former South Atlantic League rivals the Lexington Legends. The Power joined the Legends in the Atlantic League of Professional Baseball, an independent MLB Partner league, for the 2021 season and beyond.^[7][8]

On September 28, 2021, the team officially changed their name to the Charleston Dirty Birds, a reference to the canary in a coal mine.^[3] Charleston won the second-half Southern Division championship, but fell short in the playoffs, losing to the eventual league champion Lexington Legends in the decisive third game of their playoff series.
