“The peace which Kulin Ban purchased by yielding to Rome was not of long duration, for he could not compel his people to observe its terms. On his death (1216) the Pope appointed a Roman Catholic Ban, and sent a mission to convert the Bosnians. The churches of the country, however, increased the more, and spread into Croatia, Dalmatia, Istria, Carniola and Slavonia. Some six years later the Pope, despairing of converting the Bosnians by other than forcible methods, and encouraged by the success of his crusade in Provence, ordered the King of Hungary to invade Bosnia. The Bosnians deposed their Roman Catholic Ban and elected a Bogomil, Ninoslav. For years the war went on, with varying fortune. Ninoslav yielded to circumstances and became a Roman Catholic, but no change in their rulers affected the faith and confession of the great bulk of the people. The country was devastated, but whenever the invading armies withdrew, the churches were found still existing, and the industry of the people quickly restored prosperity. Fortresses were erected throughout the country “for the protection of the Roman Catholic Church and religion”; the Pope gave the land to Hungary, which long ruled it, but its people still holding to their faith, he at length called a crusade of “all the Christian world” against it; the Inquisition was established (1291), and Dominican and Franciscan brothers competed in applying its terrors to the devoted churches.”
