Francis II, Duke of Saxe-Lauenburg
Francis II of Saxe-Lauenburg (Ratzeburg, 10 August 1547 – 2 July 1619, Lauenburg upon Elbe), was the third son of Francis I of Saxe-Lauenburg and Sybille of Saxe-Freiberg (Freiberg, 2 May 1515 – 18 July 1592, Buxtehude), daughter of Duke Henry IV the Pious of Saxony. From 1581 on he ruled Saxe-Lauenburg as duke. Life As the third born son and with primogeniture in Saxe-Lauenburg Francis II made a military career in imperial services. In 1571 his highly indebted father Francis I resigned in favour of his eldest surviving son Magnus II, who had promised to redeem the pawned ducal demesnes with funds he gained as Swedish military commander and by his marriage to a Swedish princess. However, Magnus did not redeem pawns but further alienated ducal possessions, which ignited a conflict between Magnus and his father and brothers as well as the estates of the duchy, further escalating due to Magnus' violent temperament. In 1573 Francis deposed Magnus and reascended to the throne. The following year Magnus hired troops in order to take Saxe-Lauenburg with violence. Francis II, an experienced military commander, and Duke Adolphus of Holstein-Gottorp, then Lower Saxon Circle Colonel (Kreisobrist), then helped Francis I to defeat Magnus. In return Saxe-Lauenburg had to cede the bailiwick of Steinhorst to Adolphus' Holstein-Gottorp in 1575. Francis II again helped his father to inhibit Magnus' second military attempt to overthrow his father in 1578. Francis I then made Francis II his vicegerent actually governing the duchy. In 1581 – shortly before he died and after consultations with his son Prince-Archbishop Henry of Bremen and Emperor Rudolph II, but unconcerted with his other sons Magnus and Maurice – Francis I made his third son Francis II, whom he considered the ablest, his sole successor, violating the rules of primogeniture. This severed the anyway difficult relations with the estates of the duchy, which fought the ducal practice of growing indebtedness. Francis only officiated as administrator of Saxe-Lauenburg. Magnus appealed at Rudolph II, who in 1585 finally decided in favour of Francis II, as agreed with Francis I in 1581. Francis II, who meanwhile had won his brother Maurice, by sharing the reign with him, lured Magnus into a trap and captured him later in 1585. Francis and Maurice kept their brother imprisoned for the rest of his life, mostly in the castle of Ratzeburg, where he died in 1603. The violation of the primogeniture, however, gave grounds for the estates to perceive the upcoming duke as illegitimate. This forced Francis II into negotiations, which ended on 16 December 1585 with the constitutional act of the "Eternal Union" () of the representatives of Saxe-Lauenburg's nobility and cities, Lauenburg upon Elbe and Ratzeburg, then altogether constituted as the estates of the duchy, led by the Land Marshall, a hereditary office held by the family von Bülow. Francis II accepted their establishment as a permanent institution with a crucial say in government matters. In return the estates accepted Francis II as legitimate and rendered him
