明代のオルドス : 天順・成化時代

Abstract

The article treats the following problems related to the defence of Ordos against the invasions of the Mongols during the T'ienhsun and Ch'enghua eras: first, the penetration during the Cheng t'ung (正統) and Chingt'ai (景泰) eras of the Mongols into Ordos with its geographical and historical background; secondly, activities of the two Mongol leaders, Bolai in the T'ienhsun era and Oroju in the Ch'enghua era; thirdly, Molikhai's invasion of North China and the construction of the Ordos Long Wall. Regarding the last point it is pointed out that the Ming built up a strong defence system under Wan Yueh(王越) and Yu Tsu-chun (余子俊) with Yulin (楡林) as headquarters against the invasion of the Mongols under Molikhai, and the present Ordos Long Wall extending from Yulin to Humach'ieh (花馬池) was constructed by Yu Tsuchun who set up the colonial militia inside Ordos.
