Which countries occupy the Scandinavian Peninsula?

The Scandinavian Peninsula is a peninsula in Northern Europe, which generally comprises the mainland of Sweden, the mainland of Norway (with the exception of a small coastal area bordering Russia) and the northwestern area of Finland.

Please note that the Scandinavian Peninsula differs from Scandinavia. The name of the peninsula is derived from the term Scandinavia, the cultural region of Denmark, Norway and Sweden. That cultural name is in turn derived from the name of Scania, the region at the southern extremity of the peninsula which has during periods been part of Denmark, which is the ancestral home of the Danes, and which is now part of Sweden.

The Scandinavian Peninsula is the largest peninsula of Europe, larger than the Balkan, the Iberian and the Italian peninsulas. During the Ice Ages, the sea level of the Atlantic Ocean dropped so much that the Baltic Sea, the Gulf of Bothnia and the Gulf of Finland disappeared, and the countries now surrounding them, including Germany, Poland, the other Baltic countries and Scandinavia, were directly joined by land.
