1777) was a Serbian hajduk (brigand) active in the Ottoman territories in western Balkans (sanjaks of Herzegovina, Bosnia and Montenegro).

After murdering the beys and taking their collected taxes, the family subsequently relocated to Venetian Dalmatia from where Sočivica and his brothers began their brigandage.

After decades of brigandage, and the capture of his wife and children, he retired to the Habsburg monarchy, where he was appointed commander of the Pandurs by Emperor Joseph II himself, in 1775.

[2][5] Stanko, a turbulent and ferocious person, plotted with his three brothers against their masters, but their father who was mild and pacific advised them not to act, for several years.

[7] After the murders, the family did not flee; in retaliation, the Pasha of Trebinje and the captain of the guards arrested up to 50 Christians, some of whom were executed, the other made slaves, but no suspicion fell on the brothers.

[5] The family arrived in Imotski, which at the time was under the sovereignty of the Republic of Venice (Venetian Dalmatia), and built a house and opened up a shop with excellent and expensive merchandise, with the Ottoman money, in 1745.

[5] The merchant life did not suit Stanko's activeness, thus, he and an entourage of 10 men turned to Montenegro, where they by the course of the summer massacred 40 Turks.

[5] After several expeditions, joined by one of his brothers, he returned to Imotski where he resided for 9 years, working in the trade established by his family.

[10] The father told a story in a manner posing his son as entirely innocent, and when the blood brother appeared he displayed great kindness, then went out under the pretence of seeking the finest lamb in his flock to treat Sočivica; his real intention was to deliver him to the Turks stationed in Duvno, 19 km from the house.

[10] The father, who expected his son returning with Turks, sought to gain time by equivocating, Sočivica then rashly crushed his head with a small axe, then went to an old female servant, who complied with him.

[10] As soon as he regained his arms, he left the house and lurked at a distance, to watch the event and ascertain the blood brother's treachery, of which he soon gained proof of.

[10] In August 1754, the same year when he had burnt the house, he narrowly escaped the pursuit of a party of Croats, who were out in search of him, and concluding that he was no longer safe in Venetian territory, he sent for his family to join him in Karlowitz (Sremski Karlovci), to which he travelled to by foot.

[11] His two brothers took the first opportunity to flee the Ottomans, upon which the enraged Pasha annulled the conversion of Stanislav, who had been given the name Ibrahim, and ordered for a more strained imprisonment with constant overwatch.

Would you have suffered yourself to be bound with cord like a miserable beast, and led without resistance by men, who, as soon as they arrived at a certain place, would in all probability, have put you to death?

I will assemble my friends, carry destruction wherever you reside, pillage your property, plunder your merchants; and from this moment, if you pay no attention to my entreaties, I swear that I will massacre every Turk that falls into my hands.

[14] Joseph II brought him and interrogated him, and made him repeat the main events of his life, then gave him a considerable sum of money and appointed him the harambaša of the Pandurs.
