made of H. Renter’s Geschichte Alexanders III. vnd der Kirche
seiner Zeit (3 vols., Berlin, 1860–1864). Much information on the
policy of these popes will be found in the works on the great personages
of the time: W. Bernhardi, Lothar von Supplinburg (Leipzig,
1879), and Konrad III. (Leipzig, 1883); H. Prutz, Kaiser Friedrich I.
(3 vols., Danzig, 1871–1874); P. Scheffer-Boichorst, Kaiser Friedrichs

The pontificate of Honorius III. is dealt with by J. Clausen in his Papst Honorius III. (Bonn, 1895), and his registers have been published by P. Pressutti (3 vols., Rome, 1884 and 1888–1895).

The publication of the registers of Innocent IV. was undertaken by Elie Berger (1881 et seq.), and those of Alexander IV. by J. de Loye, A. Coulon and C. Bourel de la Roncière (1895 et seq.). As the history of the later Hohenstaufens is intimately bound up with that of the contemporary popes, mention must be made of F. W. Schirrmacher, Die letzten Hohenstaufen (Göttingen, 1871); A. Karst, Geschichte Manfreds vom Ende Friedrichs II. bis zu seiner Krönung (Berlin, 1897); and K. Hampe, Geschichte Konradins von Hohenstaufen (Innsbruck, 1894).

(1893 et seq.); and J. Guiraud and L. Cadier, those of Gregory X. (1892 et seq.). On Gregory X., see F. Walter, Die Politik der Kurie unter Gregor X. (Berlin, 1894). The pontificate of John XXI. has been dealt with by R. Stapper, Papst Johannes XXI. (Münster i. W., 1898), and that of Nicholas III. by A. Demski, Papst Nikolaus III. (Münster i. W., 1903), in vol. vi. of the Kirchengeschichtliche Studien, ed. by Knopfler, Schrörs and Sdralek. The publication of the registers of Nicholas III. was undertaken by J. Gay (1898 et seq.). Much information on the policy of these popes will be found in the following: R. Sternfield, Ludwigs des Heiligen Kreuzzug nach Tunis und die Politik Karls I. von Sizilien (Berlin, 1896); Ch. V.

Cartellieri, Peter von Aragon und die sizilianischen Vesper (Heidelberg. 1904). On Honorius IV., see introduction to the complete edition of his registers by Maurice Prou (1886–1888). E. Langlois has published the registers of Nicholas IV. (1886–1893), and Otto Schiff deals with his pontificate in his Studien zur Geschichte Papst Nikolaus IV. (1897). On Celestine V., see H. Schulz, Peter von Murrhone (Papst Coelestin V.), Berlin, 1894. The publication of the registers of Boniface VIII. was begun by G. Digard, M. Faucon and A. Thomas (1884 et seq.). Of the vast literature on this pontificate we must content ourselves with citing: Heinrich Finke, Aus den Tagen Bonifaz’ VIII. (Münster i. W., 1902); Ch. V. Langlois, “St. Louis, Philippe le Bel, Les Derniers capétiens directs” (vol. iii., pt. ii. of Lavisse’s Histoire de France); Ernest Renan, Études sur la politique religieuse du règne de Philippe le Bel (1899); A. Baudrillart, “Des Idées qu’on se faisait au XIVᵉ siècle sur le droit d’intervention du souverain pontife en matière politique,” in the Revue d’histoire et de literature religieuses (vol. iii., 1898); and R. Holtzmann, Wilhelm von Nogaret (Freiburg i. Br., 1898). The pontificate of Benedict XL is dealt with by P. Funke in his Papst Benedikt XI. (Münster i. W., 1891). Cf. Ch. Grandjean, “Recherches sur l’administration financière du pape Benoît XI,” in the Mélanges d’archéologie et d’histoire (vol. iii., 1883), published by the French School at Rome. Grandjean has published the registers of Benedict XI. (1883 et seq.).
Among works of a more general character that throw light on the history of the papacy during the 12th and 13th centuries, the first place must be given to Walter Norden’s Das Papsttum und Byzanz. Die Trennung der beiden Mächte und das Problem ihrer Wiedervereinigung bis zuni Untergange des byzantinischen Reichs (Berlin, 1903), which contains an account of the question of the East in its relations with the papal policy, from the rise of the schism down to the end of the middle ages.
