Estonia

Estonia is a country located in eastern Europe. It is bordered by Sweden to the north and east, Muscovy to the east, Lithuania and the Livonian Order to the south, and the Baltic Sea to the west. It is a vassal state of Sweden.

History
The modern history of Estonia begins on 2 April 1457, when Sweden and the Livonian Order signed the Treaty of Abo, which ceded Osel, Reval, Dorpat, Narva, and Liefland to Sweden. The very next day, these lands were turned into the Kingdom of Estonia, a vassal nation under Sweden. Estonia later gained Riga from the Rigan War and Pskov from the War of the Rivers.

Sometime in the 1520s, Lithuania gained independence from Poland. They became a rival with Sweden and supported Estonia's independence, putting heavy strain on their relations. From 14 June 1553 to 13 July 1558 the two fought the Lithuanian War, mainly caused by this issue, after which Sweden had to cede Riga and Pskov to Lithuania.

On 1 November 1567, Estonia was integrated into Sweden.

Administration
The nation duly pays the vassal tax and transfers its trade power to Sweden. Otherwise, Sweden rarely interferes with Estonian affairs, so the area is largely autonomous.

It is a kingdom with its capital in Reval. The Swedish royal family often marries into Estonia's own royal family.
