Boluk-bashi
Ottoman officer rank equivalent to captain

Boluk-bashi (Ottoman Turkish: بولق باشی, Turkish: bölükbaşı, "head of [infantry] company, company captain") was an Ottoman officer rank equivalent to captain. It was replaced in the 19th century by the rank of yüzbaşı.
Etymology
The word is made up of two elements, bölük ("division, group of troops", from böl, "to separate") and baş ("head"). It entered into Balkan languages such as Albanian: bylykbashi and Serbo-Croatian: buljubaša.
Usage
Ottoman Empire
The bölükbaşı was an Ottoman officer rank equivalent to captain. It was used in the Janissary corps during the reign of Suleiman the Magnificent (r. 1520–66). In the 17th century the holder was in command of a bölük, a sub-division of a regiment. During the Ottoman Old Regime (1703–89) the rank translated into "captain of a squadron", commanding a bölük of the sipahi and silahdar cavalry.
It was higher than oda-bashi (lieutenant).
