Muhammad II was the true organiser of the Nasrid state with his reforms to the administration and the army. His considerable legislative activity included the institution of the Nasrid royal protocol ("rusūm al-mulk"), and of the court chancery ("al-kitāba"), in which the chief figure of his reign was the future vizier Abu Abdallah ibn al-Hakim. His reign also saw the expansion and institutionalisation of the Volunteers of the Faith (also called "ghazi"s in Arabic): soldiers recruited from North Africa to defend Granada against the Christians. Many of them were members of tribes or families which had been exiled from the Marinid state. Some of them settled in the city of Granada, establishing the quarter of Zenete (named after the Berber tribe of Zenata), and some in the western areas of the realm, such as Ronda and the surrounding area. They received payments from the state, but often came into conflict with the locals in the areas they settled. When, in the early 1280s, Granada came into conflict with the Marinids, the Volunteers remained loyal and defended Granada against Castile, when it attacked at the same time. Over time, the Volunteers became Granada's most important military force, numbering 10,000 at the end of Muhammad's rule and eclipsing Granada's locally recruited army. Their leader, the "shaikh al-ghuzat", held an influential position in Granadan politics. Different men were named as the "shaikh" by Muhammad at different points of his reign, including Ali ibn Abi Iyad ibn Abd al-Haqq, Tasfin ibn Mu'ti, Musa ibn Rahhu, Abd al-Haqq ibn Rahhu, and Ibrahim ibn Yahya.
