Albert II. Sigismund, who died in December 1437, was succeeded on the German throne and also in Hungary and Bohemia by his son-in-law Albert of Austria, and from this time, although remaining in theory elective, the German crown was always conferred upon a member of the house of Habsburg until the extinction of the male line of this family in 1740. The reign of Albert II. was too short to enable him to do more than indicate his good intentions; he acted in general with the electors in observing a neutral attitude with regard to the dispute between the council of Basel and Pope Eugenius IV., and he put forward a scheme to improve the administration of justice. He died in October 1439, and was succeeded by his kinsman Frederick, duke of Styria, who became German king as Frederick IV. and, after his coronation at Rome in 1452, emperor as Frederick III. Frederick III. and the Papacy. The first concern of the new king was with the papal schism. The council of Basel was still sitting, and had elected an anti-pope, Felix V., in opposition to Eugenius IV., while the electors, adhering to their neutral attitude, sought to bring Frederick into line with them on this question. Some years were occupied in negotiations, but the king soon showed himself anxious to come to terms with Eugenius, and about 1446 the electors ceased to act together. At length peace was made. The consent of several of the electors having been purchased by concessions, Frederick signed with Pope Nicholas V., the successor of Eugenius, in February 1448 the concordat of Vienna, an arrangement which bound the German Church afresh to Rome and perpetuated the very evils from which earnest churchmen had been seeking deliverance. Thus Germany lost the opportunity of reforming the Church from within, and the upheaval of the 16th century was rendered inevitable. Germany under Frederick.
