Duchy of Pomerania
The dynasty's dominion, Pomerelia, roughly corresponded with the area of today's Pomeranian Voivodeship in northern Poland. The Samborides from 1227 used the Medieval Latin title "dux Pomeraniae"; their Duchy of Pomerelia was therefore referred to as "Duchy of Pomerania", even though there was another Duchy of Pomerania to the west, ruled by the House of Griffins, who likewise bore the title "Dukes of Pomerania".
