The Estonian Cultural Autonomy law that was passed in 1925 was unique in Europe at that time. Cultural autonomies could be granted to minorities numbering more than 3,000 people with longstanding ties to the Republic of Estonia. Before the Soviet occupation, the Germans and Jewish minorities managed to elect a cultural council. The Law on Cultural Autonomy for National Minorities was reinstated in 1993. Historically, large parts of Estonia's northwestern coast and islands have been populated by indigenous ethnically Rannarootslased (Coastal Swedes).
