Franjo Ksaver Tomašić (2 October 1761 – 12 August 1831)[3] was a Croatian baron and a lieutenant field marshal of the Austrian Empire's Army who served as a First Governor of Kingdom of Dalmatia between 1815 and 1831.

He eventually survived thanks to the end of Reign of Terror and help by the Fortress commander, Colonel Beck who praised him before the emperor Francis II for his courage and merit.

However, he did not stay long on the position because he was given the command to join general Alexander Suvorovs' units that Russia sent to Italy to assist France during the French Revolutionary Wars.

At the time of the Napoleonic Wars in 1809, at the Siege of Palmanus', Tomašić was assigned to the main Austrian army headquarters and promoted to the rank of Major General on 22 August.

After French occupied parts of the Austrian Empire, from which they created Kingdom of Illyria, he was named commander of Leopoldstadt, and become a member of a commission, led by general baron Knežević, that set new borders between France and Austria on the Croatian territory.
