Since the 11th Century, the non-agricultural people became jinin (associates of Shinto shrines) because they presented their products to the major temples and shrines, however, the residents of Kurodo dokoro and mikuriya (manors of Imperial Family and powerful shrines) which was controlled by mikuriya (the place to cook for Emperor) which was under Kurodo dokoro were called Kugonin when a policy of directly controlling mikuriya which had been set in mountains, fields, rivers, and sea to enrich the economy of the court was taken under the administration of Emperor Gosanjo.
11世紀以降、非農業民は有力寺社などに生産物を貢納することを理由に、これらに隷属する神人となっていたが、後三条天皇親政下において、内廷経済を充実させるべく山野河海に設定されていた御厨を直轄化するという政策がとられると、蔵人所とその下部組織である御厨所の所管となった御厨の住民が供御人と呼ばれるようになった。
