What were the most successful basketball teams of the 1870s?

There were no basketball teams in the 1870s as basketball was not invented until December 1891 by Canadian physical education instructor James Naismith. The first official basketball game was played on December 21, 1891, between Naismith's students at the International YMCA Training School in Springfield, Massachusetts.

However, in the early 1900s, basketball became popular in the United States and several professional and amateur teams were formed. The most successful teams of the early 1900s include the New York Celtics, the Original Celtics, and the Harlem Globetrotters.

The New York Celtics were a professional basketball team that played from 1914 to 1950. They were one of the most successful basketball teams of their time and won multiple championships. The Original Celtics were a barnstorming team that played from 1915 to 1939. They were known for their fast-paced style of play and for popularizing basketball in the United States. The Harlem Globetrotters were founded in 1926 and are known for their entertaining and innovative style of play. They have played exhibition games all over the world and have become one of the most recognizable basketball teams in the world.
