king. This seemed to be the most logical course since Prussia was the strongest of the German states, as well as the largest in geographic size. Meanwhile, center-right revolutionaries sought some kind of expanded suffrage within their states and potentially, a form of loose unification. Finally, the Polish majority living in the share of Polish territory annexed by Prussia pursued their own liberation agenda. Frankfurt Parliament Their pressure resulted in a variety of elections, based on different voting qualifications, such as the Prussian three-class franchise, which granted to some electoral groups—chiefly the wealthier, landed ones—greater representative power. On 27 March 1849, the Frankfurt Parliament passed the Paulskirchenverfassung (Constitution of St. Paul's Church) and offered the title of Kaiser (Emperor) to the Prussian king Frederick William IV the next month. He refused for a variety of reasons. Publicly, he replied that he could not accept a crown without the consent of the actual states, by which he meant the princes. Privately, he feared opposition from the other German princes and military intervention from Austria or Russia. He also held a fundamental distaste for the idea of accepting a crown from a popularly elected parliament: he would not accept a crown of "clay". Despite franchise requirements that often perpetuated many of the problems of sovereignty and political participation liberals sought to overcome, the Frankfurt Parliament did manage to draft a constitution and reach an agreement on the kleindeutsch solution. While the liberals failed to achieve the unification they sought, they did manage to gain a partial victory by working with the German princes on many constitutional issues and collaborating with them on reforms. The aborted 1848–49 German Empire in retrospective analysis Scholars of German history have engaged in decades of debate over how the successes and failures of the Frankfurt Parliament contribute to the historiographical explanations of German nation building. One school of thought, which emerged after The Great War and gained momentum in the aftermath of World War II, maintains that the failure of German liberals in the Frankfurt Parliament led to bourgeoisie compromise with conservatives (especially the conservative Junker landholders), which subsequently led to the so-called Sonderweg (distinctive path) of 20th-century German history. Failure to achieve unification in 1848, this argument holds, resulted in the late formation of the nation-state in 1871, which in turn delayed the development of positive national values. Hitler often called on the German public to
