Princess Uliana Olshanska (Lithuanian: Julijona Alšėniškė or Julijona Vytautienė, Polish: Julianna Holszańska; d. 1448) was a noblewoman from the Alšėniškiai family and the Grand Duchess of Lithuania as the second wife of Vytautas, Grand Duke of Lithuania.
German chronicle of Johann von Posilge[1] and Polish historian Jan Długosz asserted that Ivan was murdered so that widowed Uliana could marry Vytautas.
[1] After the death of his first wife Anna on 31 July 1418, Vytautas wished to marry Uliana, daughter of one of his closest allies Ivan Olshansky.
Piotr Krakowczyk, Bishop of Vilnius, refused to perform the wedding ceremony due to this relationship and demanded they seek approval from the pope.
Jan Kropidło, Bishop of Włocławek, performed the ceremony before Christmas 1418[1] and, eventually, Vytautas obtained a matrimonial dispensation from Pope Martin V.[5] It appears that the marriage was a loving one, but they had no children.
