Henry IV (14 June 1463 – 23 June 1514), called the Elder (German: Heinrich der Ältere), a member of the House of Welf, was Duke of Brunswick-Lüneburg and ruling Prince of Wolfenbüttel from 1491 until his death.
Henry's father, Duke William IV of Brunswick-Lüneburg retired in 1491, leaving government of the Principality of Brunswick-Wolfenbüttel with Caleneberg to his two sons Henry the Elder and Eric, and only kept the Principality of Göttingen for himself. In 1494, the brothers divided their territories between them: Henry received the eastern part of the state, with the cities of Brunswick and Wolfenbüttel, while Eric took over the Calenberg estates.[citation needed]
Starting in 1492, Henry laid siege to the City of Brunswick for a year and a half to enforce tax payments; the siege ended with a compromise. On 24 November 1498 Henry IV, Magnus and the latter's father John V, Duke of Saxe-Lauenburg allied in order to conquer the Land of Wursten, a de facto autonomous region of free Frisian peasants in a marsh at the Weser estuary, under the loose overlordship of the Prince-Archbishopric of Bremen.[1] Henry obliged to send 3,000 lansquenets to the Land of Hadeln, the Lauenburgian exclave serving as beachhead, with the lansquenets meant to gain their payment by looting and plundering the free peasants of Wursten, once successfully subjected.[2]
On 16 November, Prince-Archbishop Johann Rode of Bremen had prepared for this by concluding a defensive alliance with Hamburg, fearing for its military outpost Ritzebüttel at the Outer Elbe protecting free navigation from and to the city.[1] Rode gained more allies on 1 August 1499 (Bremen city, Buxtehude, Ditmarsh, and Stade), providing 1,300 warriors and equipment to defend Wursten and / or invade Hadeln, and waged a pre-emptive feud on John V and his allies on 9 September 1499.[3] Rode's allied forces easily conquered the Land of Hadeln.[4]
By 20 November 1499 Magnus hired the so-called GreatorBlack Guard of ruthless and violent Dutch and East Frisian mercenaries, commanded by Thomas Slentz, recapturing Hadeln in early 1500.[4][5] By early December 1499 Rode had addressed Duke Henry IV for help, who was actually allied with Magnus.[6] In return Rode offered to appoint Henry's 12-year-old son Christopher as his coadjutor, a position usually (ascoadiutor cum iure succedendi), and in this case indeed, entailing the succession to the respective see.[6] This exactly accomplished Henry's own expansionist ambitions, so he converted to Rode's column.[7]
Henry IV and his troops were then hunting the Black Guard. Mediated by Eric I, Duke of Brunswick-Lüneburg, Prince of Calenberg and Henry IV, Rode and Magnus concluded peace on 20 January 1500.[7] Hadeln was restored to Magnus, thus no substantial change as compared with the status quo ante.[8]
On 1 February Rode and Bremen's cathedral chapter officially appointed Christopher as coadjutor.[8] Rode and chapter had agreed to pay for Christopher's necessary papal dispensation from the canon-law age limit, as he was too young to be coadjutor, while Henry IV guaranteed military support for the prince-archbishopric.[8] In 1501, Henry attacked Frisian Butjadingen, in order to subject it to the Prince-Archbishopric of Bremen, but he had to abort the campaign. On 7 May 1501 Pope Alexander VI dispensed Christopher from being underage, which cost the Bremian see 1,500 Rhenish guilders.[8] Alexander VI confirmed Christopher as coadjutor under the proviso that he should only ascend to office having come of age (27 years), which was in 1514.[8] However, Christopher de facto assumed the rule in 1511, after Rode's death.[citation needed]
In 1509 Magnus and Henry's daughter Catherine married, which sealed the reconciliation of Henry and Magnus. In 1511, Henry, together with the other members of the House of Brunswick-Lüneburg, conquered the County of Hoya, which had refused to recognize Brunswick-Lüneburg as its liege lord. A second attack on East Frisia in 1514—in the course of the Saxon Feud—led to Henry's death; his head was shot off during the siege of Leerort Castle (today part of Leer).
Henry married Catherine of Pomerania, daughter of Eric II, Duke of Pomerania, in 1486. They had the following children:
