1876 | PHILADELPHIA, PENNSYLVANIA – The National League played its first game on this date in 1876. The Boston Red Stockings (current Atlanta Braves) beat the Philadelphia Athletics (long since defunct) 6 to 5. It became known as the Senior Circuit because it existed for 25 years before the American League.
The National League was started by several teams from the National Association, which basically went belly-up with the birth of the NL. The new league went through many changes in its first few seasons. Some teams folded and some got kicked out. It’s a wonder the league survived. According to several sources, the eight charter franchises were variations of the:
Boston Red Caps (the current Atlanta Braves)
Chicago White Stockings (the current Chicago Cubs)
Cincinnati Red Stockings or Reds
Hartford Dark Blues
New York Mutuals
St. Louis Brown Stockings
Only two of the original eight National League teams remain; the White Stockings, which are now the Cubs, and the Boston Red Caps, now the Atlanta Braves. None of the other teams made it into the 20th Century. They all folded.
Some of the names are familiar only because franchises that came along later liked to use old names. By 1900, eight franchises were in place that exist today, though some names and addresses would change, they are the Braves, Dodgers, Cubs, Reds, Giants, Phillies, Pirates, and Cardinals.
