Robert de Clary, a knight from Picardy, who presents the non-official
view of the Crusade, as it appeared to an ordinary soldier. The

(composed in Greek verse some time after 1300, apparently by an author of mixed Frankish and Greek parentage, and translated into French at an early date under the title “The Book of the Conquest of Constantinople and the Empire
of Rumania”) narrates in a prologue the events of the Fourth (as indeed also of the First) Crusade. The Chronicle of the Morea (as
this work is generally called) is written from the Frankish point of view, in spite of its Greek verse; and the Byzantine point of view
must be sought in Nicetas.[1]
The history of the later Crusades, from the Fifth to the Eighth, enters into the continuations of William of Tyre above mentioned; while the Historia orientalis of Jacques de Vitry, who had taken part in the Fifth Crusade, and died in 1240, embraces the history of events till 1218 (the third book being a later addition). The Secreta fidelium Crucis of Marino Sanudo, a history of the Crusades written by a Venetian noble between 1306 and 1321, is also of value, particularly for the Crusade of Frederick II. The minor authorities for the Fifth Crusade have been collected by Röhricht, in the publications of the Société de l’Orient Latin for 1879 and 1882; the ten valuable letters of Oliver, bishop of Paderborn, and the Historia Damiettina, based on these letters, have also been edited by Röhricht in the Westdeutsche Zeitschrift für Geschichte und Kunst (1891). The Sixth Crusade, that of Frederick II., is described in the chronicle of Richard of San Germano, a notary of the emperor, and in other Western authorities, e.g. Roger of Wendover. For the Crusades of St Louis the chief authorities are Joinville’s life of his master (whom he accompanied to Egypt on the Seventh Crusade), and de Nangis’ Gesta Ludovici regis. Several works were written on the capture of Acre in 1291, especially the Excidium urbis Acconensis, a treatise which emerges to throw light, after many years of darkness, on the last hours of the kingdom. The Oriental point of view for the 13th century appears in Jelaleddin’s history of the Ayyubite sultans of Egypt, written towards the end of the 13th century; in Maqrizi’s history of Egypt, written in the middle of the 15th century; and in the compendium of the history of the human race by Abulfeda (†1332); while the omniscient Abulfaragius (whom Rey calls the Eastern St Thomas) wrote, in the latter half of the 13th century, a chronicle of universal history in Syriac, which he also issued, in an Arabic recension, as a Compendious History of the Dynasties.
II. The documents bearing on the history of the Crusades and the Latin kingdom of Jerusalem are various. Under the head of charters come the Regesta regni Hierosolymitani, published by Röhricht, Innsbruck, 1893 (with an Additamentum in 1904); the Cartulaire générale des Hospitaliers, by Delaville Leroulx (Paris, 1894 onwards); and the Cartulaire de l’église du St Sépulcre, by de Rozière (Paris, 1849). Under the head of laws come the assizes of the Kingdom, edited by Beugnot in the Recueil des historiens des croisades; and the assizes of Antioch, printed at Venice in 1876. G. Schlumberger has written on the coins and seals of the Latin East in various publications; while Rey has written an Étude sur les monuments de l’architecture militaire (Paris, 1871). The genealogy of the Levant is given in Le Livre des lignages d’outre-mer (published along with the assizes).
Bibliographies.—The best modern account of the original authorities for the Crusades is that of A. Molinier, Les Sources de l’histoire de France, vols. ii. and iii. W. Wattenbach’s Deutschlands Geschichtsquellen gives an account of Albert of Aix (vol. ii., ed. 1894, pp. 170-180) and of Ekkehard of Aura (ibid. pp. 189-198). Von Sybel’s Geschichte des ersten Kreuzzüges contains a full study of the authorities for the First Crusade; while the prefaces to Hagenmeyer’s editions of the Gesta and of Ekkehard are also valuable. Gaston Dodu, in the work mentioned below, begins by a brief account of the original authorities, which is chiefly of value so far as it deals with William of Tyre and the history of the assizes; and H. Prutz has also a short account of some of the historians of the Crusades (Kulturgeschichte, pp. 453-469). Finally reference may be made to the works of Kugler and Klimke above mentioned, and to J. F. Michaud’s Bibliographie des croisades (Paris, 1822).
Modern Writers.—The various works of R. Röhricht present the soundest, if not the brightest, account of the Crusades. There is a Geschichte des ersten Kreuzzugs (Innsbruck, 1901), a Geschichte des Königreichs Jerusalem (ibid. 1898) and a Geschichte der Kreuzzüge in Umris (ibid. 1898). For the First Crusade von Sybel’s work and Chalandon’s Alexis Ier Comnène may also be mentioned; for the Fourth A. Luchaire’s volume on Innocent III: La Question d’Orient; while for the whole of the Crusades Norden’s Papstum und Byzanz is of value. B. Kugler’s Geschichte der Kreuzzüge (in Oncken’s series) still remains a suggestive and valuable work; and L. Bréhier’s L’Église et l’orient au moyen âge (Paris, 1907) contains not only an up-to-date account of the Crusades, but also a full and useful bibliography, which should be consulted for fuller information. On points of chronology, and on the relations between the crusaders and their Mahommedan neighbours, W. B. Stevenson’s The Crusaders in the East (Cambridge, 1907) is very valuable. On the constitutional and social history of the Latin kingdom of Jerusalem Dodu’s Histoire des institutions du royaume latin de Jérusalem is very useful; E. G. Rey’s Les Colonies franques en Syrie contains many interesting details; and Prutz’s Kulturgeschichte der Kreuzzüge contains both an account of the Latin East and an attempt to sketch the effects of the Crusades on the progress of civilization. The works of Gmelin and J. Delaville-Leroulx on the Templars and Hospitallers respectively are worth consulting; while for Eastern affairs the English reader may be referred to G. Lestrange’s Palestine under the Moslem, and to Stanley Lane-Poole’s Life of Saladin and his Mahommedan Dynasties (the latter a valuable work of reference). (E. Br.)
CRUSENSTOLPE, MAGNUS JAKOB (1795–1865), Swedish historian, early became famous both as a political and a historical writer. His first important work was a History of the Early Years of the Life of King Gustavus IV. Adolphus,
which was followed by a series of monographs and by some politico-historical novels, of which The House of Holstein-Gottorp in Sweden is considered the best. He obtained a great influence
over King Charles XIV. (Bernadotte), who during the years 1830–1833
gave him his fullest confidence, and sanctioned the official
character of Crusenstolpe’s newspaper Fäderneslandet. In the
last-mentioned year, however, the historian suddenly became
the king’s bitterest enemy, and used his acrid pen on all occasions
in attacking him. In 1838 he was condemned, for one of these
angry utterances, to be imprisoned three years in the castle of
Waxholm. He continued his literary labours until his death
in 1865. Few Swedish writers have wielded so pure and so
incisive a style as Crusenstolpe, but his historical work is vitiated
by political and personal bias.
CRUSIUS, CHRISTIAN AUGUST (1715–1775), German philosopher and theologian, was born on the 10th of January 1715 at Lenau near Merseburg in Saxony. He was educated at Leipzig, and became professor of theology there in 1750, and
principal of the university in 1773. He died on the 18th of
October 1775. Crusius first came into notice as an opponent
of the philosophy of Leibnitz and Wolff from the standpoint of
religious orthodoxy. He attacked it mainly on the score of the
moral evils that must flow from any system of determinism, and
exerted himself in particular to vindicate the freedom of the will.
The most important works of this period of his life are Entwurf
der nothwendigen Vernunftwahrheiten (1745), and Weg zur
Gewissheit und Zuverlässigkeit der menschlichen Erkenntniss
(1747). Though diffusely written, and neither brilliant nor
profound, Crusius’ philosophical books had a great but short-lived
popularity. His criticism of Wolff, which is generally
based on sound sense, had much influence upon Kant at the
time when his system was forming; and his ethical doctrines
are mentioned with respect in the Kritik of Practical Reason.
Crusius’s later life was devoted to theology. In this capacity his
sincere piety and amiable character gained him great influence,
and he led the party in the university which became known as
the “Crusianer” as opposed to the “Ernestianer,” the followers
of J. A. Ernesti. The two professors adopted opposite methods
of exegesis. Ernesti wished to subject the Scripture to the same
laws of exposition as are applied to other ancient books;
Crusius held firmly to orthodox ecclesiastical tradition. Crusius’s
chief theological works are Hypomnemata ad theologiam propheticam
(1764–1778), and Kurzer Entwurf der Moraltheologie
(1772–1773). He sets his face against innovation in such matters
as the accepted authorship of canonical writings, verbal inspiration,
and the treatment of persons and events in the Old
Testament as types of the New. His views, unscholarly and
uncritical as they seem to us now, have had influence on later
evangelical students of the Old Testament, such as E. W.
Hengstenberg and F. Delitzsch.
There is a full notice of Crusius in Ersch and Gruber’s Allgemeine Encyclopädie. Consult also J. E. Erdmann’s History of Philosophy; A. Marquardt, Kant und Crusius; and art. in Herzog-Hauck, Realencyklopädie (1898). (H. St.)
