response from the European Catholic monarchs was weak: French interest, moreover, lay in an alliance with the Turks against the Habsburgs. Furthermore, the Catholics of the Ottoman world received a protector at the Porte in the person of the French ambassador. In this way the Roman Catholic millet was established at the start of the Tanzimat reforms. Circassians The high numbers of Circassians in the Ottoman Empire was mainly due to the Crimean War. During the last years of the war and the years to follow, many Circassians fled the empire through The Black Sea. Circassians in the Ottoman Empire, despite being Muslim, mainly kept to themselves and maintained their separate identity, even having their own courts, in which they would tolerate no outside influence. History Use for Sassanid Empire In a 1910 book William Ainger Wigram used the term melet in application to the Persian Sassanid Empire, arguing that the situation there was similar to the Ottoman millet system and no other term was readily available to describe it. Some other authors have also adopted this usage. The early Christians there were forming the Church of the East (later known as the Nestorian Church after the Nestorian schism). The Church of the East's leader, the Catholicos or Patriarch of the East, was responsible to the Persian king for the Christians within the Empire. This system of maintaining the Christians as a protected religious community continued after the Islamic conquest of the Sassanids, and the community of Nestorian Christians flourished and was able to send missionaries far past the Empire's borders, reaching as far as China and India. 19th century (Reformation Era) In 1839 and 1856 multiple reforms were attempted with the goal of creating equality between the religious communities of the Ottoman Empire. In wake of these reforms multiple different new millets emerged, notably for multiple Eastern Catholic and Protestant Christian communities. Millets were also now to have there internal rule reviewed by the central government and clerics within the millet in order to keep their power in check. Many clerics of the millet system pushed back against these reforms as they believed it was meant to weaken millets and the specialized power they had built for themselves. These millets, refusing to withdraw there autonomy slowed down the attempted reforms and the general impact they were attempting to make on the equality of religious communities.
