Extract

The great Mongol invasion of Eastern Europe in 1241–2 has received a fair degree of attention from historians.1 The same cannot be said of the crusade it provoked: at least from a crusading vantage-point this paper could be subtitled ‘a neglected category‘. The general histories of the crusades are content, at most, to mention the invasion and the proclamation of the crusade against the Mongols by Pope Gregory ix; some omit any reference to the episode. And if the Mongols receive more notice in Maureen Purcell's investigation of papal crusading policy in the thirteenth century, it is nevertheless in rather general terms; there is no mention of the crusade of 1241. The only author to examine that crusade at all qua crusade seems to have been Paulus in his history of the Indulgence.

The evidence quoted is a sentence in a letter of Frederick 11, HDFS v. 1152 = CM iv. 116; but what the emperor is actually voicing is a general complaint that Gregory has launched against him a crusade (i.e. since 1239) which ought to have been sent against Saracens and Mongols, and cannot be taken as referring to any diversion of the anti-Mongol crusade. This is not to deny that in Italy, on the other hand, Gregory was still encouraging resistance to Frederick at the time of his death, as shown by his letter to the Genoese, 16 Aug. 1241, MGH Epp. s.

The phrase ‘remissio omnium peccatorum’ occurs in HDFSv. 1212, but in the context of crusaders rendering each other mutual assistance against those who harm them–sicut Tartaros; it appears in ’Ann. Worm.’, 46. Nonspecific references to the indulgence offered by Siegfried are made by Henry, bishop of Constance, in HDFS v. 1214, and by Siboto, bishop of Augsburg, Hormayr-Hortenburg, Die goldene Chronik ii. 71 no. 12. Although the vow is mentioned, I have encountered the term ‘pilgrimage’ only in the charter of Count Albert of Tyrol, Huter, Tinier Urkundenbuch iii. 180 no. 1137* = Hormayr-Hortenburg, Die goldene Chronik ii. 64, ’si in itinere peregrinationis sue decesserit’.
