The History of the Vartanants Saints (formerly, the History of Vartan and the Armenian War) is a major source for the Battle of Avarayr, its causes and aftermath. Much more, it is a panegyric of the saints who were martyred in the course of the war. The History covers the thirty-six-year period from AD 428 to 464 in seven chapters. Volume I contains the first four chapters and covers the period from the fall of the Armenian Arsacid dynasty (428 AD) to the events that led to the Battle of Avarayr (451).
