Germany. From 1949 until 1989, Germany was divided between two countries: West Germany, with a capital in Bonn, and East Germany with a capital in East Berlin.
That was NATO. Both Canada and the USA were founding members with the 10 western European countries in 1949.
It was founded in 1949 for the economic cooperation of the Eastern European countries. Failed because the soviet Union was unable to provide much financial aid.
In 1921, Ireland became an independent country but chose to remain part of the British Commonwealth. In 1949, the Irish people voted to become a republic and the country changed its name to the Republic of Ireland and withdrew from the British Commonwealth.
