Of all the Serbian lands, Lazar's state lay furthest from Ottoman centres, and was least exposed to the ravages of Turkish raiding parties. This circumstance attracted immigrants from Turkish-threatened areas, who built new villages and hamlets in previously poorly inhabited and uncultivated areas of Moravian Serbia. There were also spiritual persons among the immigrants, which stimulated the revival of old ecclesiastical centres and the foundation of new ones in Lazar's state.[8]
