Livonian and Estonian nobles delivered a note of independence to Soviet representatives in Stockholm on January 28, 1918, announcing their intention to break away from Russia under the rights granted to them by the Treaty of Nystad of 1721. In response, the Bolsheviks, who controlled Estonia, arrested 567 leading Germans and deported them to Russia. After the signing of the Treaty of Brest-Litovsk they were allowed to return. Under German-Soviet treaties, Germany gained control over Courland, Riga, Saaremaa (Ösel), Livonia and Estonia.[citation needed]
