While most readers familiar with Spanish history are no strangers to the Carlos school, there may be many who are less familiar with Spanish history or the Carlos school. The author will provide a brief explanation of the Spanish Carlos school here; readers already familiar with this period of history can skip this section.
Before Queen Isabella, Spain had a male-only succession system, so the Carlos faction had no say in the matter.
However, Queen Isabella's father, Fernando VII, only had two daughters. In order to keep the throne in his own family, Fernando temporarily amended the succession law to grant Isabella the right to inherit.
Amending the succession law is one thing, but Isabel is only three years old and clearly unsuitable to be king.
This displeased Prince Carlos, the younger brother of Fernando VII who was supposed to inherit the throne. In addition, the nobles who originally supported the Salic law of succession (male succession) united and called Prince Carlos Carlos V, which is the origin of the Carlos faction.
Readers can search online for information about the subsequent Carlos Wars; they all ended in failure.
In short, the Carlos faction was essentially a power struggle within the Bourbon family, but ultimately it was still the Bourbon family. (Important point)
Also, I'm asking for monthly votes, requests to read further, recommendations, and investments for my new book! Feel free to discuss anything in the book review section; I'll read and answer them when I have time.
