In June 1875, Christians started the Herzegovina uprising; Catholics of Gabela, led by Ivan Musić—who was Kraljević's nephew—were the first to rebel. The Ottoman authorities asked Kraljević to help them to pacify the rebels but this bid failed and the Ottoman authorities allowed foreign powers to find a peaceful solution. The representatives of the United Kingdom, Germany, Russia, Austria-Hungary, Italy and France arrived in Mostar. Buconjić issued a booklet in Italian called "The Main Reasons for the Uprising of the Christian Population in Herzegovina" and gave it to six foreign consuls. In this booklet, Buconjić stated high taxes were the main factor in the uprising.
