Why is "Captaincies in Bosnia and Herzegovina" trending?

Wikipedia Overview

The captaincy was a military–administrative unit within the Bosnia Eyalet of the Ottoman Empire. The Ottoman captaincy was a sub-division within a sanjak and existed exclusively in the territory of the Bosnia Eyalet from the 16th century until 1835. It was headed by a captain who commanded the garrison of at least one fortress and exercised authority over the surrounding district. The institution developed along the Habsburg–Ottoman and Venetian–Ottoman frontiers and later spread into the interior of Bosnia. By the late 18th and early 19th century there were around forty captaincies covering much of the eyalet, especially in border regions along the Sava, Una and Neretva rivers. The system was abolished in 1835 as part of Ottoman centralising reforms, but leading captaincy families continued to play an important role in Bosnian politics, most notably in the Bosnian uprising led by captain Husein Gradaščević.
