Ivan Bušić (1745–1783), nicknamed Roša (from Italian rosso, "red", as in red-haired) was a hajduk (guerilla fighter) harambaša (commander)[1] from the Imotski frontier (Imotska krajina, in modern Croatia), who served the Republic of Venice against the Ottomans in Dalmatia, Bosnia and Herzegovina.
According to his descendant, Bruno Bušić, he was Croat, evident from the poem La trnka urekla Hrvata.
[3] As a hajduk, he fought against the Ottoman Empire, traveling along Dalmatia, Bosnia and Herzegovina.
According to contemporary annals, he persecuted more Orthodox (Serbs) than Turks, because he "couldn't listen or look at them, so he killed many of them".
[6] In 1977, Croatian dissident in emigration and Bušić family member Bruno Bušić wrote a book Ivan Bušić-Roša, Hajdučki Harambaša, detailing the life and legend of Ivan Bušić-Roša.
