Recap
Following the demise of the original Negro National League in 1931, economic conditions during the Great Depression prevented the ANL, EWL, and NSL from restoring professional negro league baseball.
Finally, in 1933, owners of 7 negro league teams, led by Gus Greenlee, ratified a constitution and organized the second Negro National League.
The league lasted until 1948, the year after Major League Baseball integrated by signing Jackie Robinson. The surviving teams merged into the Negro American League.
I sincerely appreciate the research work, and the information being shared. It is important and interesting history.
