<P> The following is a history of the Pittsburgh Pirates of Major League Baseball . </P> <P> Professional baseball has been played in the Pittsburgh area since 1876 . The teams of the era were "independents", barnstorming throughout the region and not affiliated with any organized league, though they did have salaries and were run as business organizations . In 1882, the strongest team in the area joined the American Association as a founding member . Their various home fields in the 19th century were in a then - separate city called Allegheny City, across the Allegheny River from Pittsburgh . The team was listed as "Allegheny" in the standings, and was sometimes called the "Alleghenys" (not the "Alleghenies") in the same generic way that teams from Boston, New York, and Chicago were sometimes called the "Bostons", the "New Yorks", and the "Chicagos", in the sports writing style of that era . After five mediocre seasons in the A.A., Pittsburgh became the first A.A. team to switch to the older National League in 1887 . At this time, the team renamed itself the Pittsburgh Alleghenys, although Allegheny remained a separate city until it was annexed by Pittsburgh in 1907 . At that time, owner - manager Horace Phillips sold the team to Dennis McKnight; Phillips stayed on as manager . </P> <P> In those early days, the club benefited three times from mergers with defunct clubs . The A.A. club picked up a number of players from a defunct Columbus, Ohio, team in 1885 . </P>
