Nassau

Nassau was never an important German state and it was because of its insignificance one of its count, Adolf, was elected to be king of Germany 1292. His attempt to create a large territorial power base by annexing Meissen and Thuringia got him deposed as king and he was killed in battle against is successor 1298. Before that had the county of Nassau been partitioned between the Walramian and Ottonian lines of the house of Nassau. The counts belonging to the Ottonian line are recorded in a separate page and would later become kings over the Netherlands, England and Scotland. The Walramian line on the other hand underwent further partitions, two of its branches became elevated to principalities. The two remaining Walramian lines were 1806 elevated to duchies and all Nassau was 1814-1816 united by the Walramian branch Nassau-Weilberg. The united Nassau was however conquered by Prussia in 1866 and became a part of its province Hessen-Nassau. This province was merged with other states after the Second World War and became the German part state of Hessen.
