- Germany from 1250 to 1493
The Great Interregnum
In Germany the death of Frederick II ushered in the Great Interregnum (1250–73), a period of internal confusion and political disorder. The antikings Henry Raspe (landgrave of Thuringia, 1246–47) and William of Holland (ruled 1247–56) were elected by the leading ecclesiastical princes at the behest of the papacy. William’s title was recognized initially only in the lower Rhineland, but his marriage to Elizabeth of Brunswick in 1252 ensured his acceptance by the interrelated princely dynasties of northern Germany. The death of the Hohenstaufen Conrad IV left William without a rival in Germany. His growing strength and independence enabled him to escape from the tutelage of his ecclesiastical electors and to devote himself to purely dynastic policies. He pursued his feud with Margaret, countess of Flanders, over their conflicting territorial claims in Zeeland at the mouth of the Rhine. He renewed the attempts of his dynasty to obtain complete mastery of the Zuider Zee by thrusting eastward into Friesland; he died at the hands of the Frisians in 1256.
Pope Alexander IV forbade the election of a Hohenstaufen but interfered no further with the succession. Hence the initiative was taken by a small group of influential German princes, lay and ecclesiastical, acting out of self-interest. None desired the election of a ruler powerful enough to threaten their growing independence as territorial princes; nor did they single out a German candidate, who might prove to be as uncontrollable as William. Archbishop Conrad of Cologne approached Richard, earl of Cornwall, brother of Henry III of England. Richard’s gifts and assurances of future favour bought him the votes of the archbishops of Cologne and Mainz, the count palatine of the Rhine, and Otakar II of Bohemia. He was formally elected in 1257 and crowned king at Aachen (Aix-la-Chapelle). Three months after Richard’s election, Alfonso X of Castile, who aspired to the empire in order to strengthen his foothold in Italy, was chosen in similar fashion by the archbishop of Trier, the duke of Saxony, the margrave of Brandenburg, and the duplicitous Otakar.
The candidates were distracted by the turbulence of the aristocracy in their countries—Richard paid four fleeting visits to Germany; Alfonso failed to appear at all. Each appealed to the papacy for confirmation of his election. Their claims were summarized in Urban IV’s bull Qui coelum (1263), which assumed that the exclusive right of election lay with the seven leading princes involved in the double election of 1257.
