The nominal governor of the country was the Turkish vali, who resided at Banjaluka or Travnik, and rarely interfered in local affairs, if the taxes were duly paid.
Below him ranked the newly converted Moslem aristocracy, who adopted the dress, titles and etiquette of the Turkish court, without relinquishing their language or many of their old customs. They dwelt in fortified towns or castles, where the vali was only admitted on sufferance for a few days; and, at the outset, they formed a separate military caste, headed by 48 kapetans - landholders exercising unfettered authority over their retainers and Christian serfs, but bound, in return, to provide a company of mounted troops for the service of their sovereign.
