Why read an interpretation of a historical event when you can read an eye-witness account. The History Matters series bypasses secondary sources to give you the primary source to start your historical inquiry. The fourth crusade is a highly contentious episode in the history of the crusades. It was here that the Latin-led crusaders turned on their own resulting in the attack on Constantinople, home of the Greek and Eastern Christians which ultimately led to the schism between the Greek and Latin churches. Originally written in French, not Latin, this eye-witness memoir by one of the crusaders is a must-read if one wants to get into the real history of the fourth crusade.
