The book I read was Football in the SEC (southeastern conference). At the very beginning of the conference it was called the SIAA. The seven original schools were Alabama, Auburn, Georgia, Georgia Tech, North Carolina, Sewanee, and Vanderbilt. Some of the most heated rivalries in the SEC developed in the first ten years of the SIAA. At one point the conference stretched from Maryland to Texas. By 1920 the conference had grown to thirty teams. That was too many. Out of the SIAA they formed the southern conference. That was a fourteen team conference, and then in 1922 seven more teams joined. Then they formed the Atlantic coast conference and the southeastern conference or SEC. Two teams left the SEC and they were left with ten teams. Arkansas and South Carolina joined to form the current twelve teams of the conference. This book is a great for people into football. It explains the origin of the greatest conference in college football.
