Episode #1.1 - S1-E1
Factual error: The American flag shown waving outside the White House is the current present-day flag with 50 stars. From 1896 to 1908, (the time period that this show is set in) the US flag only had 45 stars as Oklahoma, New Mexico, Nebraska, Alaska and Hawaii were not recognised as states in that time period. The flag did not have 50 stars until 1960. (00:04:30)
Episode #1.1 - S1-E1
Factual error: In the flashback that shows the fate of Ae-sin's parents whilst Ae-sin is a baby, several characters can be seen using a Mauser C96 pistol. These include the father when he tries to shoot Wan-ik, the mother when the soldiers come for her, and the man standing beside Wan-ik who shoots the father. The flashback takes place over 20 years before the main story takes place, which would have set it in the 1870s, but the Mauser C96 pistol was not first designed until 1895. (00:56:10 - 00:58:03)
