Despite being a fiction with all the letters, Outlander it is also based on the real history of Scotland. Like any country in the world, the home of Jamie and Claire in the first seasons was also the victim of bloody wars that went down in history, especially because of how that affected the future of the inhabitants.
At present Scotland is considered a city of England and, this union began precisely at the time that it is set Outlander. In 1700, the Kings of Scotland, Jacobo Estuardo and Clementina Sobieski were dismissed by the redcoats, the same army that integrates Black Jack Randall (Tobías Menzies) in the series.
Likewise, this fiction based on the books of Diana Gabaldón also recounts the moment in which the son of Jacobo, Carlos Estuardo, was appointed Regent to direct the affairs of his family and eventually return his father to the throne. That is why, in 1745, he led the first Jacobite uprising with troops from the Scottish Highlanders, the same as Jamie and his uncle, Dougal MacKenzie.
Furthermore, Charles Stuart was the same one who forced the Scots to appear at the famous Battle of Culloden. According to what he relates Outlander, this confrontation was one of the bloodiest in the history of Scotland where thousands of lives were lost and, as if this were not enough, the lives of Jamie and Claire had to go their separate ways.
And while many of the things that were shown in the series were nothing more than fiction, the Stuarts are an important part of the story. So much so that, after the interest it generated Outlander Worldwide, many productions were launched to tell the life, from different perspectives, of this family that was removed from the throne.
The two queens Y Reign are two of the clear examples of how the Stuarts began to be part of the general interest.
