After Gerhard I's death in 1290 his three younger sons partitioned Holstein-Itzehoe and Schaumburg into three branches, with Adolph VI the Elder, the third brother, getting Holstein-Pinneberg and Schaumburg south of the Elbe, the second brother Gerhard II the Blind getting Holstein-Plön, and the fourth Henry I receiving Holstein-Rendsburg.
His full title, as immortalized on his coffin, was: Frederick, the brave hero, Landgrave of Hesse, Prince of Hersfeld, Count of Katzenelnbogen, Diez, Ziegenhain, Nidda and Schaumburg.
The County of Schaumburg proper was partitioned among the Schaumburg heirs into three parts, one incorporated into the ducal Brunswick and Lunenburgian Principality of Lüneburg, the second becoming the County of Schaumburg-Lippe and the third continuing the name County of Schaumburg, ruled in personal union by Hesse-Cassel.
Historically it consisted of the former states of Schaumburg-Lippe in the area of Bückeburg - Obernkirchen and Stadthagen and the County of Schaumburg in the area of Rinteln.
