Their mission was to engage in ghazah, or razzia in Italian, raiding European coastal cities and islands primarily to capture slaves, whom they sold in Algeria and Morocco. All coastal areas were prey, but Italy was the most ravaged of all, partly due to geographical proximity.
The first wave of pillaging and slave-trading occurred during the Mameluk period of Egypt (7th-15th centuries). At that time, pirates were slave soldiers, mostly nomadic Kipchak Turks that had converted to Islam. The second wave of incursions took place during the reign of the Ottoman Empire (present-day Turkey).
The most famous of all pirates were the Barbarossa brothers, who were of Turkish origin but inherited their nickname from the Italians, who called them “Red Beard.”
Most legendary of the four was Kheir ed-Din (1474-1518), who became admiral of the sultan’s Ottoman fleet, which, after assaulting the coasts of Sardinia in 1544, landed on the islands of Ischia and Procida in the Bay of Naples.

As for men’s attire, the Barbary period spans many centuries and geographical locations, so we can only summarize the looks and styles.
The dress during the first wave would have been identical to what the men wore in North Africa, slowly evolving into the Arab dress as seen in the photo to the middle right.
The pre-Islamic basis of clothing was a short, flowing, unbelted tunic and loose outer wrappings. The Romans noted that the North Africans draped animal skins over the left shoulder.
With the spread of Arab influence, men wore head coverings like hooded cloaks or a winding cloth around the head, as well as long robes, wrapping mantles, and sandals.
