1634: The Ram Rebellion is the seventh published work in the 1632 alternate history book series, and is the third work to establish what is best considered as a "main plot line or thread" of historical speculative focus that are loosely organized and classified geographically. The initial main thread is called the "Western and North-Central Europe thread" ; the second plot line, encompassing events in Italy, Spain, the Mediterranean region, and France, the "South European thread", and this book can be considered the starting novel of the "South-Central/South-East thread" being set in southern Germany, Austria, Bavaria, and Bohemia. This geographically organized plot thread actually began in Ring of Fire in Flint's novelette "The Wallenstein Gambit" which is set in Bohemia, Austria, and Germany, which tied into stories in various Grantville Gazettes.

The 1632 series, also known as the 1632-verse or Ring of Fire series, is an alternate history book series and sub-series created, primarily co-written, and coordinated by American author Eric Flint and published by Baen Books.
