For a series produced for the History channel, this series has serious historical issues. The events depicted in the series happen in 1306 (15 years after the siege of Acre in 1291). However:
- Jacques de Molay was the Grand Master of the Knights Templar from 1292 to 1307 when the order was dissolved by Pope Clement V
- Pope Boniface VIII died in 1303, 3 years before these events; in 1306 pope was Clement V
- Joan I of Navarre, wife of King Philip IV, died in 1305
- Isabella of France, was born in 1295, and therefore 11 years old in 1306, although some sources put her birth on 1292 in which case she would have been 15 at the times depicted in the series, which is probably her age in the series.
Most of the main characters in these historical series either didn't exit at all, were dead at the time of the events, or had little to do with the events depicted.
When it comes to historical accuracy this series fails miserably, like many others I have seen in recent years. History seems to be less interesting than the imagination of screen writers who sell fiction as facts to uneducated viewers.
