Constitution and Playing Rules of the National League of Professional Base Ball Clubs (1876)
From WikiLeague, the free baseball governance encyclopedia.
The founding document of organized professional baseball. Adopted February 2, 1876, by the eight original National League clubs at a meeting in New York's Grand Central Hotel. Principally architected by William A. Hulbert (Chicago White Stockings owner), with Albert Spalding as a key collaborator. The Constitution established the basic structure of the modern professional sports league: club ownership controls, exclusive territorial rights, league-administered discipline, common playing rules, and the contractual framework that became the precursor to the formal reserve clause adopted in 1879. The text is the documentary ancestor of every subsequent MLB governance instrument represented in this archive — the 1903 National Agreement, the 1921 Major League Agreement, and the modern MLB Constitution chain (2005, 2008, 2013-through-2018). Transcribed by John Thorn, the Official Historian of Major League Baseball; this is the most authoritative public transcription available.
Background
Earliest governance document in the archive. The reserve clause that the Messersmith arbitration (in this archive) overturned a century later traces back to the contractual framework established here. The Hulbert-era clubs-control-labor structure is the documentary baseline against which every subsequent MLB labor instrument can be read. John Thorn's transcription is the most authoritative public-source version; Thorn is the Official Historian of Major League Baseball and works from Hall of Fame Library originals.
