Inspired by Mike Stearns' scheme of launching the American Revolution "150 years early", the Committees of Correspondence, based on the original organized bodies from the revolution, are one of the first institutions influencing European thought and the neo-historical developments. Headed by Gretchen Richter, the Committees start from a seed population in Jena that was planted in 1632 even as the Americans march to their second deliberate battle in defense of a community of Greater Thuringia, Germany. These committees spread throughout Europe, playing a large role in the liberation of Hamburg in 1634.
