Oliver Jens Schmitt (born 15 February 1973 in Basel) is a professor of South-East European history at Vienna University since 2005.

Der neue Alexander auf dem Balkan, a critical biography of George Castrioti-Skanderbeg, caused a debate in Albania.

[2] A Swiss national daily newspaper Tages-Anzeiger published Schmitt's interview given to Enver Robelli in Tirana on 25 February 2009, in which it is emphasized that Schmitt claims that Skanderbeg's mother Voisava was Serbian, a member of the Branković family and that the Kastrioti surname probably is derived from Greek word kastron (fort).

[4] Ardian Klosi, who translated his book from German to Albanian, was accused of treason.

[5] Schmitt, in response to critics, said that he had never claimed Skanderbeg was Serbian and furthermore states that he considers him to have been an Albanian.
