The Order of March is a precedence ordered list of everyone in the Kingdom, as of today. The Order of March will change as individuals become landed Baronages, Heirs, or Crowns.
Precedence is granted by Awards, Grants, and Patents of Arms (Patents are awarded with Peerages). For awards of equal rank, they are ranked by date given. Territorial Baronage, Royal Peers, Heirs, and Sovereigns process at the head of the March.
