Frederick's death is ancillary to the study of genocide because of his known critique of German conservatism. British Prime Minister William Gladstone described him as the "Barbarossa of German liberalism."
As the Crown Prince, he often opposed the conservative Chancellor Otto von Bismarck, particularly in speaking out against Bismarck's policy of uniting Germany through force, and in urging that the power of the Chancellorship be curbed. Liberals in both Germany and his wife's native Britain hoped that as emperor, Frederick III would move to liberalize the German Empire.
The premature demise of Frederick III is considered a potential turning point in German history; and whether or not he would have made the Empire more liberal if he had lived longer is still debated.
