Götaland (listen (help·info)), Gothia, Gothland, Gautland, Geatland is a historical land of Sweden. Geographically it is located in the south of Sweden, bounded to the north by Svealand, with the deep woods of Tiveden, Tylöskog and Kolmården marking the border.
Götaland once consisted of petty kingdoms, which its inhabitants called Gautar in Old Norse. It is generally agreed that these were the same as the Geatas, the people of the hero Beowulf in England's national epic by the same name. The region is also the traditional origin of the Goths (more specifically the island of Gotland in the Baltic Sea).

Etymology
Västergötland and Östergötland, once rival kingdoms themselves, constitute Götaland proper. The Geatish kings, however, belong to the domain of Norse mythology.
Geatland is the land in which the medieval hero of the poem,Beowulf, is said to have lived.
It was only late in the Middle Ages that Götaland began to be perceived as a part of Sweden. In Old Norse and in Old English sources, Gautland/Geatland is still treated as a separate country from Sweden. In Sögubrot af Nokkrum for instance, Kolmården between Svealand and Östergötland is described as the border between Sweden and Ostrogothia (...Kolmerkr, er skilr Svíþjóð ok Eystra-Gautland...), and in Hervarar saga, king Ingold I rides to Sweden through Östergötland: Ingi konungr fór með hirð sína ok sveit nokkura ok hafði lítinn her. Hann reið austr um Smáland ok í eystra Gautland ok svá í Svíþjóð. The lord, Bo Jonsson Grip, was probably the one who was best acquainted with the geography of the Swedish kingdom since he owned more than half of it. In 1384, he stated in his will that the kingdom consisted of Swerige (Sweden, i.e. Svealand), Österland (i.e. Finland) and Göthaland (i.e. Götaland).
The small countries to the south of Finnveden, Kind, Möre, Njudung, Tjust, Tveta, Värend, Ydre were merged into the province of Småland (literally: [the] "small countries"). Off the coast of Småland was the island of Öland, which became a separate province.
Dal to the north west became the province of Dalsland.
Småland, Öland and Dalsland were already seen as lands belonging to Götaland in (Scandinavian) medieval times (12th–15th century).
In the Treaty of Roskilde (1658), the Danish kingdom ceded what is today often referred to as Skåneland and Bohuslän to Sweden. Skåneland, which had constituted the eastern part of Denmark, became the Swedish provinces of Skåne, Halland and Blekinge. The new provinces came to be counted as part of Götaland.
The island of Gotland shifted allegiance between the Swedes and the Danes several times. Although the island may be perceived to have closer links to Svealand or to Denmark (Scania), it is counted as belonging to Götaland.
Värmland originally belonged to the Göta Court of Appeal, but the province changed to become part of the Court of Appeal for Svealand for a period of time in the early 19th century. Even though Värmland historically was a part of Götaland, it has since that time generally been counted as part of Svealand, although it is now part of the Court of Appeal for Western Sweden.

History
Today, Götaland has no administrative function and is thus an unofficial entity, but it is generally considered to be one of three Swedish lands or regions. It is made up of ten provinces, based loosely on the area originally under the jurisdiction of the Göta Court of Appeals (established in 1634), to which the Scanian lands, Gotland and Bohuslän were added in 1658-1679:

Skåne, Blekinge and Halland were a Danish land known as the Scanian lands or the Eastern Province until 1658 when the Treaty of Roskilde ceded the region to Sweden. Furthermore, Bohuslän belonged to Norway until 1658, and Gotland belonged to Denmark 1361-1645 and 1676-1679. Since 1820, Scania and Blekinge form a separate court of appeal district under the Scania and Blekinge Court of Appeal in Malmö.
