The Ottoman government gave the "Hamidiye" and the Kurdish tribes' rulers power because the government feared the growth of Armenian nationalism. The "Hamidiye" became famous across the world when they took part in pogroms, attacking the Armenian people in the east of Anatolia between 1894 and 1896. The government gave many tribes' rulers good treatment. Sheikh Said Berzinci became the ruler of Sulaymaniyah, and had a good relationship with the Ottoman government in Mosul. Said Berzinci became the most important of the government's friends in the Mosul Vilayet. Milli Ibrahim Pasha was ruler from the tribes; he was an important military officer in the "Hamidiye" and a friend of the sultan. The power, tyranny, and violence of the "Hamidiye" and some of the Kurdish tribes' rulers made some other Kurds unhappy. Many of the Kurdish professionals and intellectuals were part of the constitutionalist political groups. They were against the Islamism of Sultan Abdul Hamid and the autocracy of his government.
