This list of rulers of Estonia starts with the ancient counties (maakond) and parishes (kihelkond) each headed by Seniores and Meliores (Elders) as noted by Henry of Livonia. The administrative jurisdiction of the parish and county elders was limited, the counties themselves remained autonomous until the Teutonic and Danish conquest of Estonia in the 13th century. Ending with the states and the rulers of states (starting from the time of the first successful Danish conquest in 1219) who either ruled or laid claims of sovereignty over some parts of the territory of present-day Estonia, as well as the leaders of the independent Republic of Estonia since 1918.
