(Abolished 15 November 1918)
Adolf II, Prince of Schaumburg-Lippe
Adolph succeeded his father as Prince in 1911, until he was forced to abdicate on 15 November 1918.
Following the German revolution: the Principality became the Free State of Schaumburg-Lippe.
Adolf married Ellen Bischoff-Korthaus, they were both killed in a plane crash in Mexico in 1936, in a controlled flight into the side of a volcano.
He was succeeded as head of the House of Schaumburg-Lippe by his brother Wolrad.

Prince Adolph's brother Prince Friedrich Christian, was son of Georg, the reigning Prince of Schaumburg-Lippe, and Princess Marie Anne.
Friedrich's brother Adolf II was the "last German prince forced to abdicate.
After WWI, Friedrich Christian was an ardent Nazi Party supporter, and worked vigorously to gain noble and royal support for it, and eventually became an upper privy councillor and adjutant to Propaganda Minister Joseph Goebbels.
In 1939, Friedrich Christian was asked to become king of Iceland by Icelanders sympathetic to the Nazi party, but refused due to the opposition of Foreign Minister Joachim von Ribbentrop.
Prince Friedrich felt disillusioned by the abdication of Emperor Wilhelm II, and even more unhappy over the "cowardly abdications" of the German princes in 1918.
The prince wished for a restoration of the monarchy, he believed that Adolf Hitler was also in tandem with these views, writing in his diary, "Hitler was in principle for the monarchy, but not for the continuation of that which, in his opinion, had failed totally."
The prince "liked to think the "National Socialists as true heirs of the old nobility."

The House of Schaumburg-Lippe had ten members in the Nazi party.
Hitler wanted these high-ranking members of society for propaganda reasons – the more who joined, the more socially acceptable his new regime would be.
Like Friedrich and his brother Prince Wolrad, Hitler appointed many of these new members to the Sturmabteilung as stormtroopers.
Hitler made various assurances to its members, leading them to believe he intended to restore the monarchy.

Friedrich Christian was a speaker for the Nazi Party in 1929, and worked vigorously to gain the support of other noble families behind Hitler.
He worked closely with Propaganda Minister Joseph Goebbels.
Goebbels gave him a position in the newly created Ministry of Public Enlightenment and Propaganda.
By April 1933, Friedrich Christian was both an upper privy councillor and Goebbels' adjutant.
That year, the prince arranged for the Minister's involvement in the Berlin University book burning.
As evident from photographs and diaries during that time, Hitler and Goebbels both held Friedrich Christian in high esteem.
As WWII continued with German military defeats, Hitler became more suspicious of royal and noble families, questioning their loyalties.
By 1943 he secretly ordered all Nazi bureaucracies to compile a record of members, and then personally decided if they were to be "retired" or allowed to stay.
Most of the princes were unwillingly booted out of the party as a result.
Goebbels went to Hitler to protect Friedrich Christian, who obtained a special waiver, for the prince's "future deployment in the Propaganda Ministry".

In 1947, four German princes Friedrich Christian, Prince August Wilhelm of Prussia, Prince Philipp of Hesse, and Hereditary Prince Ernst of Lippe, were brought under arrest to the war crimes jail at Nuremberg in order to appear as witnesses in a portion of the 16 trials of high-ranking Nazi criminals.
Viewed as an "old-line party member" who made propaganda excursions to many foreign countries on Goebbels' behalf, Friedrich Christian was the last of the four to testify.
