Aiboland (also known as Swedish Estonia and Egeland) is the Estonian Swedish name for the historically Swedish-speaking areas and towns of northern and western Estonia.
Historical Aiboland encompasses Noarootsi, Vormsi, Ruhnu, Osmussaar, Hiiumaa, Saaremaa, Muhu, Naissaar, and the towns around Haapsalu on the Estonian mainland.
During World War II, in the summer of 1944, nearly all of the Estonian Swedes living in Aiboland fled to Sweden before the Red Army invaded and re-occupied the Baltic States.
