Swedes (svenskar) are an ethnic group native to the Nordic region, primarily their nation state of Sweden, who share a common ancestry, culture, history and language. They mostly inhabit Sweden and the other Nordic countries, in particular Finland where they are an officially recognized minority, with a substantial diaspora in other countries, especially the United States.
The English term "Swede" has been attested in English since the late 16th century and is of Middle Dutch or Middle Low German origin. In Swedish, the term is svensk, which is from the name of svear (or Swedes), the people who inhabited Svealand in eastern central Sweden, and were listed as Suiones in Tacitus' history Germania from the first century AD. The term is believed to have been derived from the Proto-Indo-European reflexive pronominal root, , as the Latin suus. The word must have meant "one's own (tribesmen)". The same root and original meaning is found in the ethnonym of the Germanic tribe Suebi, preserved to this day in the name Swabia.
Like other Scandinavians, Swedes descend from the presumably Indo-European Battle Axe culture and also the Pitted Ware culture. Prior to the first century AD there is no written evidence and historiography is based solely on various forms of archeology. The Proto-Germanic language is thought to have originated in the arrival of the Battle Axe culture in Scandinavia and the Germanic tribal societies of Scandinavia were thereafter surprisingly stable for thousands of years. The merger of the Battle Axe and Pitted Ware cultures eventually gave rise to the Nordic Bronze Age which was followed by the Pre-Roman Iron Age. Like other North Germanic peoples, Swedes likely emerged as a distinct ethnic group during this time.
Swedes enters written proto-history with the Germania of Tacitus in 98 AD. In Germania 44, 45 he mentions the Swedes (Suiones) as a powerful tribe (distinguished not merely for their arms and men, but for their powerful fleets) with ships that had a prow in both ends (longships).
