Svealand consists of the capital region Mälardalen in the east, Roslagen in the north-east, the former mining district Bergslagen in the center, and Dalarna and Värmland in the west.
It includes an extensive archipelago of thousands of small islands in Södermanland and Uppland and has lakeshores on the four largest lakes in the country.
Svealand generally has a moderate continental climate with a gradual decline of precipitation and increase of temperatures moving eastwards as the elevation descends.
The older name of Sweden in Swedish, Svea rike (modern spelling: Sverige) Realm of the Swedes, "Swea Region", originally only referred to Svealand.
Svealand and Götaland were also divided by deep forests, which prevented both polities from being controlled effectively.
