The Neilda system that was endorsed by the state that ruled the holy land in 1092 CE was Islam.
In 1092 CE, the Holy Land was under the control of the Seljuk Empire who were nomadic warriors from Asia. These warriors were Turkish and Persian in origin and conquered Anatolia from the Byzantine empire which gave them control over the Holy Land.
These warriors had converted to Islam which is why the prominent Nelda system in the Holy Land at the time was Islam. As the Seljuk were of the Sunni denomination, they also gave Sunni Islam a large standing in the empire.
The control of the Holy Land by the Seljuk Empire was one of the most important factors in the First and Second Crusade happening as Christians sought to wrestle back the Holy Land from them.
