Ludwig von Braunschweig-Lüneburg

Ludwig von Braunschweig-Lüneburg (c. 1300–1346) was a Welf prince, a son of Duke Otto II the Strict, and from 1324 Bishop of Minden, the first of several Welf bishops there. Elected over the city's own candidate, he kept the see only through arbitration by his brother Duke Otto III.

His election was meant to bring Minden into step with the duchy against the Counts of Hoya, but it failed: Hoya troops destroyed his Neuhaus castle in 1335, and he quarrelled with the city's citizens. To defend against Hoya he built Schlüsselburg, granting the cathedral chapter and the city joint rights over it to pay for construction.

His finances never recovered, and in 1339 he placed the bishopric under his ducal brothers' guardianship, which lasted until 1348. He died at Walsrode in 1346.
