County of Nassau

thumb|[[Nassau Castle]]

The County of Nassau was a German state within the Holy Roman Empire from the period of the formal recognition of the countly title in 1159 (though "de facto" sovereignty began in 1125) until the declaration of the Duchy of Nassau in 1806 with the creation of the Confederation of the Rhine. Through succession, it had many counts ruling parts of it, mostly or completely independent of one another. After many of these counts were promoted to princely status, the County was promoted and thus was known as a Princely County or as the Principality of Nassau.

Origins

Nassau, originally a county, developed on the lower Lahn river in what is known today as Rhineland-Palatinate. The town of Nassau was founded in 915. Dudo of Laurenburg held Nassau as a fiefdom as granted by the Bishopric of Worms. His son, Rupert, built the Nassau Castle there around 1125, declaring himself "Count of Nassau". This title was not officially acknowledged by the Bishop of Worms until 1159 under the rule of Rupert's son, Walram. By 1159, the County of Nassau effectively claimed rights of taxation, toll collection, and justice, at which point it can be considered to become a state.
