At a meeting between the American Association and the National League, the Tripartite Agreement (or “National Agreement”) is drafted

On February 17 1883 — At a meeting between the American Association and the National League, the Tripartite Agreement (or “National Agreement”) is drafted. In it the two leagues, along with the Northwestern League, agree to respect each other’s contracts, ending a brief period of player raids. Also, the reserve rule is amended to allow each team to reserve 11 players, an increase of 6. The National Agreement will usher in a period of peaceful coexistence, lasting until the Players League war of 1890.
