Count John VII the Middle of Nassau-Siegen (7 June 1561 – 27 September 1623), German: Johann VII. der Mittlere Graf von Nassau-Siegen, official titles: Graf zu Nassau, Katzenelnbogen, Vianden und Diez, Herr zu Beilstein, was since 1606 Count of Nassau-Siegen, a part of the County of Nassau, and the progenitor of the House of Nassau-Siegen, a cadet branch of the Ottonian Line of the House of Nassau.
John was one of the most important military theorists of his time,[1] who introduced many innovations and inventions. His Kriegsbuch contained all the military knowledge of his time, but also many new ideas, which made an essential contribution to the reform of the Dutch States Army by his cousin Maurice.[2] John served in the Dutch States Army,[2][3][4][5] was colonel general of the Palatinate[6] and commander-in-chief of the Swedish army.[1][6][7] His reputation reached far beyond the borders of the Holy Roman Empire.[1] As a mediator, John successfully continued the example set by his grandfather William the Rich.[8]
