Cathay as "Cathay" (in a number of spelling variants) as well. The name occurs in the writings of Giovanni da Pian del Carpine (c. 1180–1252) (as "Kitaia"), William of Rubruck (c. 1220–c. 1293) (as "Cataya" or "Cathaia"). Rashid-al-Din Hamadani, ibn Battuta, Marco Polo all were referring to Northern China as Cathay, while Southern China, ruled by the Song dynasty, was "Mangi", "Manzi", "Chin", or "Sin". The word "Manzi" (蠻子) or "Mangi" is a derogatory term in Chinese meaning "barbarians of the south" ("Man" was used to describe unsinicised Southern China in its earlier periods), and would therefore not have been used
