The Gesta Francorum Iherusalem peregrinantium (A history of the expedition to Jerusalem) is a Latin chronicle of the First Crusade written on 1101, 1106, 1124 until 1127 by Fulcher of Chartres (c. 1059 – after 1128).

He served Baldwin I of Jerusalem for many years, and wrote a chronicle of the Crusade, writing in Latin.

[2] Included in the chronicle is his account of Pope Urban II's November 1095 speech at the Council of Clermont where Urban calls for the First Crusade: [Your] brethren who live in the east are in urgent need of your help, and you must hasten to give them the aid which has often been promised them.

For, as the most of you have heard, the Turks and Arabs have attacked them and have conquered the territory of Romania [the Greek empire] as far west as the shore of the Mediterranean and the Hellespont, which is called the Arm of St. George.

[3] At the earliest, Fulcher began his chronicle in the late autumn of 1100, or at the latest in the spring of 1101, in a version that has not survived but which was transmitted to Europe during his lifetime.
