Curoniian kings were a privileged group. But they were not a nobility group.During the 18th century, in the territories of what is now Latvia and Estonia, what was the status of the descendants of indigenous nobility/chiefs? I am asking about all areas, such as those under Swedish control, Russian control, Duchy of Kurland-Semigalia, and Polish-Lithuanian control.
I am aware of a few indigenous groups, like the "Curonian Kings", who survived the German crusader era into the early-modern period. But I don't know what was the status of people like that, or other descendants of indigenous Latvian and Estonian nobility, by the 18th century?
