Why do the Vatican guards have to be Swiss?

The most famous priesthood army in the world is the Swiss Guard: Established in 1956 by Pope Giulio, the Swiss Guard was sworn in on May 6 to commemorate the deaths of 147 Swiss soldiers who died on May 6, 1527, defending Pope Clément VII against German mercenaries who were invading Rome. The duty of the Swiss Guard is to protect the Pope and his residence. The uniform of the Swiss Guard was designed by Michelangelo. The original Vatican had national guards, but after a battle, all the national guards fled, and only the Swiss Guard swore to protect the Pope to the safety of his residence, and after that, the Holy See only employs Swiss mercenaries to this day.
