In the Crusader period, Ga’aton (named Iazon) was mentioned in 1160, when it and several other villages in the area of Castellum Regis was transferred to a Crusader named Iohanni de Caypha(Johannes of Haifa). In 1182 Jazun was especially excluded from the list of estates belonging to Jocelyn III in the area.
In 1220, when Jocelyn III’s daughter Beatrix de Courtenay and her husband Otto von Botenlaubensold Mi’ilya and its dependencies to the Teutonic Knights, Ga’aton (called Ihazon, Jaharon, Jaroth) was again explicitly excluded from the sale.
In documents dating to 1253 (Jasson) and 1256, (Jashon) it was included in the area of Casal Imbert.
In 1283 Ga’aton was still part of the Crusader states, as it was mentioned as part of their domain in the hudna between the Crusaders based in Acre and the Mamluk sultan Qalawun.
