Pre-state Estonian-speaking Finnic societies organized in autonomous parishes (kihelkonnad) and larger counties (maakonnad) rather than a unified kingdom, known through archaeology, Scandinavian sagas (as 'Estland'), and Henry of Livonia's chronicle of the final crusading conquest.
Conquered piecemeal during the Livonian Crusade, culminating in the fall of the last independent stronghold (Saaremaa, 1227 CE); incorporated into the crusader states of medieval Livonia, ending independent Estonian political organization until the 20th century (the modern Republic of Estonia is a separate, distinct record already in the dataset).
