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. The name comes from Sarmatia, a term used in Greco-Roman carthography, 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.
