Maximilian I, Prince of Hohenzollern-Sigmaringen

Maximilian I, Prince of Hohenzollern-Sigmaringen (20 January 1636 – 13 August 1689, in Sigmaringen) was a German nobleman. He was the third ruling Prince of Hohenzollern-Sigmaringen; he ruled from 1681 until his death.

Life
Maximilian was the son of Prince Meinrad I (1605-1681) from his marriage to Anna Marie (1613-1682), daughter of Ferdinand Baron of Törring at Seefeld. He was named after Elector Maximilian I of Bavaria, whom his father was serving at the time of his birth.

He joined the Imperial army, together with his younger brother Francis Anthony. He commanded a Dragoon regiment and, like his cousins in the Hohenzollern-Hechingen line, fought under Emperor Leopold I in the Fourth Austro-Turkish War. During the Franco-Dutch War, he commanded the imperial army on the Rhine. After the Peace of Nijmegen of 1675, Maximilian returned to Vienna.

Maximilian married Maria Clara in Boxmeer on 12 January 1666. She was the daughter of Count Albert of Berg-'s-Heerenberg. After the death of her brother Oswald III in 1712, she inherited the County of 's-Heerenberg, which thus fell to the House of Hohenzollern. Among his Dutch possessions were the Lordships of Boxmeer, Bergh, Diksmuide, Gendringen, Etten, Wisch, Pannerden and Millingen. In 1681, his father died. Maximilian divided the inheritance with his brother. Francis Anthony received the County of Haigerloch; Maximilian received the original County of Sigmaringen. He initiated various construction projects in the town of Sigmaringen, among them an expansion of Sigmaringen Castle.
