Coat of arms of the Transylvanian Saxons

The Transylvanian Saxons (German: Siebenbürger Sachsen; Transylvanian Saxon: Siweberjer Såksen or simply Soxen, singularly Sox or Soax; Transylvanian Landler: Soxn or Soxisch; Romanian: sași; seldom sași ardeleni/transilvăneni/transilvani; Hungarian: erdélyi szászok) are a people of mainly German ethnicity and overall Germanic origin—mostly Luxembourgish and from the Low Countries initially during the medieval Ostsiedlung process, then also from other parts of present-day Germany—who settled in Transylvania in various waves, starting from the mid and mid-late 12th century until the mid 19th century. The first ancestors of the Transylvanian 'Saxons' originally stemmed from Flanders, Hainaut, Brabant, Liège, Zeeland, Moselle, Lorraine, and Luxembourg, then situated in the north-western territories of the Holy Roman Empire around the 1140s and 1150s. Alongside the Baltic Germans from Estonia and Latvia and the Zipser Germans (also sometimes known or referred to as Zipser Saxons) from Zips, northeastern Slovakia, as well as Maramureș and Bucovina, the Transylvanian Saxons are one of the three eldest German-speaking and ethnic German groups of the German diaspora in Central-Eastern Europe, having continuously been living there since the High Middle Ages onwards. The Transylvanian Saxons are part of the broader group of Romanian Germans as well, being the eldest and one of the most important of all the constituent sub-groups of this ethnic community. Their native dialect, Transylvanian Saxon is close to Luxembourgish. Nowadays, organisations representing the Transylvanian Saxons exist in Romania, Germany, Austria, Canada, and the United States (in the latter case most notably 'Alliance of Transylvanian Saxons'). Other smaller communities of Transylvanian Saxons can be found in South Africa and Australia as well as South America (for example in Argentina).
