Sweden lies in the east of the Scandinavian peninsula; it was created when the Goths and Svears came together in the seventh century. In the late fourteenth century it united with Norway and Denmark and the union lasted until 1527 when Gustavs Vasa led a rebellion against Danish rule. In 1814 Denmark ceded Norway to Sweden but this union ended in 1905. Since 1814 Sweden has not fought a war and has remained neutral. Sweden's economy is highly industrialised and it relies heavily on its vast natural resources such as timber and mineral deposits. Moreover, hydroelectric power is plentiful and is exploited by industry. Lutheran Protestantism is the principal religion and Swedish the official language; however, Lapp and Finnish are also spoken.
