Sweden did try some colonialism, when it was in vogue. Not on a large scale though.

You also kind of have to count Norway as part of the larger Dano-Norwegian colonization effort with a sprinkle of the Swedish one.

- Kalmar Union (1397 - 1523)

- Dano-Norwegian Realm (1524-1814)

- United Kingdoms of Sweden and Norway (1814 - 1905)

- Independent Norway (1905 - )
