Founded: 1893, as the Toledo, Ohio franchise in the minor Western League. Moved to Boston when that league became the American League in 1900.
Team Name: The name Red Sox, chosen by owner John I. Taylor after the 1907 season, is based on an obsolete form of socks, as in the red footwear worn by the team starting in 1908. The older Boston National League club had originally been called the Red Stockings, and in fact had worn red stockings until temporarily abandoning them in 1907, which inspired the American League club owner to grab the nickname. Prior to 1908, the A.L. team in fact wore dark blue stockings, and did not have an official nickname. They were simply "the Bostons" or "the Boston Baseball club"; some newspaper writers referred to them as the Boston "Americans" (as in "American Leaguers", Boston being a two-team city) or "Somersets" (for a one-time club owner), but these were unofficial names. The team was never known as either the Boston "Pilgrims" or "Puritans". Those names were invented years later by historical revisionists.
