Hesse was a landgravate in the HRE. An important change came during 1247-64 in the Hessian-Thuringian War of Succession. Sophie of Brabant (who was supported by the Teutonic Order) made sure that Hesse stayed independent and went to her son Heinrich I "the Child". ITTL he even got a slightly bigger share, at the expense of Thuringia. During the periods of 1350-1411, 1561-80 and 1658-63, Hesse was divided into Nieder- and Oberhessen. During the Twenty-Year War, the landgravate of Hesse acquired Fulda.
