Sarmatism (pseudohistory)

In Lithuanian history, Sarmatism is a term used to refer to various nationalist pseudohistorical theories which seek to refute traditional understanding of the history of Lithuania and propose that the medieval Grand Duchy of Lithuania is a continuation of states and ethnic groups in Eastern Europe attested before the first mention of the name of Lithuania recorded in the Annals of Quedlinburg in 1009.^[1] The name comes from Sarmatia, a term used in Greco-Roman cartography, notably the Geography of Ptolemy, to label all of Eastern Europe, and which is generally believed by Sarmatist historians to refer to the extent of Antiquity-era Lithuania.

These theories lack support in the Lithuanian historical community, and are criticized for amateurish linguistics, selective use of historical data, and extreme nationalism.^[2]
