Nikola Tusun

Nikola Tusun (7 April 1899 – 1945) was a Croatian lawyer and Ustaše official in the Axis puppet state known as the Independent State of Croatia (; NDH) during World War II.

He was born in the village of , near the town of Travnik in central Bosnia whilst the region was under Austro-Hungarian rule. After completing his secondary education in Travnik and receiving his juris doctor from the University of Zagreb, he worked as a civil servant until 1929, then opened a law practice in the town of Pregrada, north of Zagreb. Between 1934 and 1940, he worked as a lawyer in Petrinja. Having previously been a member of the Croatian Peasant Party, he relocated to Travnik in 1940 and joined the fascist, Croatian nationalist Ustaše movement, which sought Croatia's secession from the Kingdom of Yugoslavia. In June 1941, several months after the NDH's establishment following the Axis invasion of Yugoslavia, Tusun was appointed Grand Prefect of Lašva–Glaž, whose administrative centre was in Travnik.

On 19 September 1941, Tusun wrote to the Directorate for Security and Public Order (; RAVSIGUR) that "a certain territory must be found where Jews from the entire country could be deported to and where they would be isolated from our people. On this territory, Jews should be guarded and supervised. In this way, we would cleanse our cities from the Jewish element." He estimated that, by mid-September, the Kruščica concentration camp in nearby Vitez held 1,539 inmates. The historian Jens Hoppe believes this figure is "most likely too low", and suggests the camp held at least 3,000 prisoners at this time, mostly Jewish women, but also around 300 Serb women from Herzegovina.

From September 1942 to late December 1943, Tusun served as the Grand Prefect of Pokuplje, whose administrative centre was in Karlovac.

Subsequently, Tusun was once again appointed as the Grand Prefect in Travnik, this time of the renamed Grand Prefecture of Lašva–Rama. He was killed by the Yugoslav Partisans in Travnik as the NDH disintegrated in 1945, alongside his wife and eldest son.
