OT:
The famous and unique Catalo-Aragonese oath of allegiance to the monarch:

Hughes, Robert (2011-12-07). Barcelona (Kindle Locations 2275-2277). Random House, Inc.. Kindle Edition.

I have to remember that one to pull into a fantasy RPG someday :)

Of course my favorite neo-feudal oath remains the one near the beginning of “The Warrior’s Apprentice”

The Sergeant opened his mouth. Miles, dropping his voice, cut across his beginning roar—by God, it was an effective trick—”Attention, please, Sergeant. I require your witness. Pilot Officer Mayhew is about to make oath.”
The Sergeant’s jaw tightened like a vise, but he came to attention.
“Put your hands between mine, Arde—like that—and repeat after me. I, Arde Mayhew—is that your full legal name? use that, then—do testify I am an unsworn freeman, and take service under Lord Miles Naismith Vorkosigan as an Armsman simple—go ahead and say that part—” Mayhew did so, rolling his eyes from left to right. “And will hold him as my liege commander until my death or his releases me.”
That repeated, Miles said, rather quickly as the crowd closed in, “I, Miles Naismith Vorkosigan, vassal secundus to Emperor Gregor Vorbarra, do accept your oath, and pledge you the protection of a liege commander; this by my word as Vorkosigan. All done—you can get up now.”
