Duchy of Brunswick-Lüneburg
The county was partitioned after Otto VIII, Count of Hoya died without sons in 1582. The majority of the territory was received by the Calenberg line with the remainder to the Lüneburg line of the Duchy of Brunswick-Lüneburg and the Landgraviate of Hesse-Cassel. The Counts of Hoya already had to recognize the Welf dukes of Brunswick-Lüneburg as liege lords in 1512.
