Who was the older brother of person whose guard formed the French Royal Guard?
Dutch grenadiers The Dutch grenadiers were a French guard regiment from 1810 until 1813. They were originally formed out of Louis Bonaparte's Royal guard.
Duke of Orléans Duke of Orléans (French: "Duc d'Orléans" ) was a title reserved for French royalty, first created in 1344 by Philip VI in favor of his son Philip of Valois. Known as princes of the blood ("princes du sang"), the title of Duke of Orléans was given, when available, to the oldest brother of the king. Thus, they formed a collateral line of the French royal family, with an eventual right to succeed to the throne should more senior princes of the blood die out.
