After King Arvedui died and Aranarth refused to ascend the throne after Angmar was defeated, what happened politically to the kingdom and the people, now that no king reigned the lands? Like, who ruled the people eventually?
Now I ain't talking about rangers, who were still ruled by Aranarth and his descendants. I'm talking about ordinary common people: peasants, craftsmen, marketwomen et cetera. Did each city/fiefdom of Arthedain become an independent city state like Bree? Or did Angmar essentially commit a genocide on the people of Arnor so that nooneno one except the rangers lived in the lands to the north of Bree anymore? And if so, how could King Aragorn Elessar restore Arnor in the Fourth Age?
