Dukes of Brunswick

The duchy of Brunswick (Braunschweig) can trace its origin back to the wedding between duke Heinrich the Proud and Gertrud the daughter of emperor Lothar 1127, that meant that Heinrich who already was duke of Saxony and Bavaria came in possession with large estates in Saxony. When his son Heinrich the Lion lost Bavaria and Saxony 1180 where these estates the only lands that remained in the house of Welf's control. The son of Heinrich the Lion, Otto, became Holy Roman Emperor 1209 in struggle with the Hohenstaufen dynasty and his son Otto the Child was elevated to duke of Brunswick and Lüneburg, i.e. the estates that since 1127 had been in the possession of the house of Welf.

As shown in the diagram above the Brunswick lands were repeatedly partitioned and merged through inheritance by members of the house of Welf.  Most of these states were short lived but two of them would be long lasting and their regents are listed in separate pages. The two states are Hanover (the pink boxes) and Braunschweig-Wolfenbüttel (the light green boxes).
