Tadeusz Józef Sulimirski[1] (1 April 1898 – 20 June 1983) was a Polish-born British[1] historian and archaeologist, who emigrated to the United Kingdom soon after the outbreak of World War II in 1939.

Sulimirski was a pioneer and leading expert in the study of the archaeology of steppe nomads, particularly the Cimmerians, Scythians and Sarmatians.

After the occupation of Poland by Nazi Germany and the Soviet Union, Sulimirski escaped to Romania, and from there he left for France.

[1] In that position he wrote a number of geopolitical propaganda articles calling for the expansion of Poland to the west through the annexation of German territory lying east of the Oder River, on the grounds that in early medieval times those territories had been part of the early Polish state.

[1] After recognition of the Polish government-in-exile was withdrawn by the Western governments, Sulimirski was a leading figure in the Committee for the Education of Poles in Great Britain.

[1][2] He gave lectures and seminars in many European countries in 1952-1965, and in a number of United States universities during a tour in 1968-1969.

[a] Sulimirski was a Fellow of the Royal Anthropological Institute of Great Britain and Ireland and the Society of Antiquaries of London.
