Prince Friedrich Christian of Schaumburg-Lippe

Like much of Germany during that period, Prince Friedrich Christian had felt disillusioned and disgusted by the abdication and flight of Emperor Wilhelm II at the end of World War I, and had felt even more unhappy over what he viewed as the "cowardly abdications" of the German princes to the revolutionaries in 1918.[4] Under the Weimar regime, many of these same princes "abandoned ancient principles of honor and fidelity and accommodated themselves to the egotistical, materialist values of the despised" new government, to Friedrich Christian's further disgust and anger.[4] The prince wished for a restoration of the monarchy, but for it to be unlike anything it had been before; 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."[4] Friedrich Christian later wrote in his 1934 work Der Adel ist tot - es lebe der Adel:

"The German nobility miserably missed its last opportunity to demonstrate its right to exist. Exceptions here only prove the rule. The question the people puts to you today is harsh and clear: Where were you noble gentlemen when Germany was in its last throes?... Where did you fight, and what sacrifices did you make? You thought of yourselves and of the welfare of your families. Maybe you lamented the wretchedness of the people, maybe it distressed you, but you did nothing! Nothing! And you still dare today to claim a leadership role?"[5]

By the mid-1920s, Friedrich Christian was fundamentally convinced that those who still treasured the old values of the nobility needed to break down the ancient barriers separating them from the common people, reach out to the masses, and side with the Nazis and their message.[6] The prince "liked to think of his own class as an 'avant-garde' of National Socialism" and of the "National Socialists as true heirs of the old nobility."[6]

Unlike many other royalty during that time, who were cautious at first of showing support to the new ideological movement, Friedrich Christian, like his brother Prince Stephan, was an early supporter of the Nazi party, officially joining the rising political group in 1929; another source however has the prince actually working with the Nazis as early as August 1928 after a relative, Hereditary Prince Ernst of Lippe, had joined three months earlier.[7][8] The House of Schaumburg-Lippe would eventually come to have ten members in the Nazi party.[9] Hitler wanted these high-ranking members of society for propaganda reasons - the more who joined, the more socially acceptable his new regime would be.[10] Like Friedrich and his brother Prince Wolrad, Hitler appointed many of these new members to the Sturmabteilung as stormtroopers, as he wanted the organization to bring together individuals from all levels of society.[11] In its early years, Hitler was more concerned with votes and finances than consistent ideology, and consequently did his best to ease and hasten the process for new members.[12] As a result, Hitler made various assurances to its new and prospective members, stating the movement had room for republicans and monarchists alike and leading them to believe he intended to restore the monarchy.[12]

Friedrich Christian was an ardent supporter of the Nazi party, becoming a speaker for the party in 1929, and working vigorously to gain the support of other noble families behind Hitler.[4][12] He worked closely with Propaganda Minister Joseph Goebbels.[13] Goebbels made a concerted effort to gain the prince's help, and gave him a position in the newly created Ministry of Public Enlightenment and Propaganda.[14] By April 1933, Friedrich Christian was both an upper privy councillor and Goebbels' adjutant.[14] In May of that year, the prince arranged for the Minister's involvement in the Berlin University book burning.[14] In 1938, the prince was sent to Sweden to drum up support for the German government; as is evident from photographs and diaries during that time, Hitler and Goebbels both held Friedrich Christian in high esteem.[4]

As World War II continued with German military defeats, Hitler became increasingly more suspicious of these high-ranking and cosmopolitan members of royal and noble families, questioning their loyalties.[15] By 1943 he secretly ordered all branches of the Nazi bureaucracies to compile a record of members with "international contacts" (often by way of a spouse), and then personally made the decision as to whether they should be "retired" or allowed to stay.[16] Most of the princes were unwillingly booted out of the party as a result.[17] Goebbels attempted to protect Friedrich Christian from these new demands by trying to obtain a special waiver; Hitler's secretary had doubts about the prince however and refused the request. Goebbels thus had to go to Hitler directly and ask for the prince's "future deployment in the Propaganda Ministry", vouching that he was "the holder of the golden badge of honor and a trusted National Socialist"; In January 1944, Hitler relented by declaring his May 1943 decree did not apply to the prince, thus allowing Friedrich Christian to continue his service to the party.[16] Unlike other Nazi-associated royalty, Friedrich Christian retained his post until 17 July 1944, when he also relinquished his commission in the SA.[16]

Although he was from one of Germany's wealthiest noble families and resided in a villa near Bonn with several servants, Friedrich Christian associated himself with the left wing of the Nazi party, stressing socialist elements in his speeches and writings.[14]

Three Icelandic Nazi sympathizers visited Friedrich Christian in 1939 and asked him to become king of Iceland when Germany took control of their country, as they hoped would happen in order to win Iceland's independence from Denmark.[7] Friedrich Christian treated this as a realistic prospect and brought it to the attention of Joseph Goebbels. In his 1952 autobiography, Zwischen Krone und Kerker, the prince recalled that Goebbels had reacted favorably to the idea, but Foreign Minister Joachim von Ribbentrop did not.[7][18]
