The Danish–Icelandic Act of Union, an agreement with Denmark signed on 1 December 1918 and valid for 25 years, recognised Iceland as a fully sovereign and independent state in a personal union with Denmark. The Government of Iceland established an embassy in Copenhagen and requested that Denmark carry out on its behalf certain defence and foreign affairs matters, subject to consultation with the Althing. Danish embassies around the world displayed two coats of arms and two flags: those of the Kingdom of Denmark and those of the Kingdom of Iceland. Iceland's legal position became comparable to those of countries belonging to the Commonwealth of Nations, such as Canada, whose sovereign is Queen Elizabeth II.
