Is Hesse Cather royalty? Please tell me their history.

It is generally believed that this "Hess Cather" refers to Prince William, but does this "Prince William" in the German royal family really exist in history?

The original text of Currency War is as follows:

After Napoleon came to power, he tried to pull Prince William to his side and became the first mouse of Prince Lian. He didn't want to take sides until the situation was unclear. Finally, Napoleon took pains to announce that "Hess Cather (Prince William's family) should be removed from the list of European rulers", and then the French army Enemy at the Gates and Prince William fled to Denmark. Before he fled, he gave Meyer a cash worth $3 million to keep on his behalf. It is this 3 million cash that brought Meyer unprecedented power and wealth, and became the first bucket of gold for Meyer to go to his financial empire.

Readers interested in history once asked, "Is this history true?" The reason for this suspicion is that this "Prince William" can't be found in the royal family of the First Reich of Germany, and there is no such family. In fact, this character is also shaped by art and cannot be found in history. No matter whether you correspond him to a prince or a noble, you can't find this person or this family.

In fact, if you look at the foreign language literature at the back, it is very clear that there is no mention of this family. When Song Hongbing translated it, he probably just flipped through it without referring to the relevant history.

In fact, there is more than one mistake in the currency war. This book says that William I established the Bank of England, and William I went to war with France. In fact, the so-called William I was originally French. Only William is mentioned in foreign literature, not many generations, because the real William should be William III. Just look it up in the book.

If the landlord wants to use the information in Currency War, he must be cautious and check whether it is true first, because this book is not an authentic historical record. However, you can look at the literature cited later.
