(a)The King of Ashur brought the people of Kusa to Eretz Yisrael and settled them in the Shomron (Samaria, hence they became known as Samaritans). They converted to Judaism after they found themselves under attack from lions. The Chachamim disagree as to whether their conversion was honest and valid (Geirei Emes) or not (Geirei Arayos, converts because of lions).
(b)After the times of the Mishnah, the Kusim were found worshipping an image of a dove and the Chachamim gave them the status of Nochrim. (According to most Rishonim, this means that they decided to treat them like Nochrim l'Chumra, even if they were Geirei Emes. According to the RAMBAM (Peirush ha'Mishnayos), however, this means that they decided that their conversion was not sincere and deemed them Nochrim (Geirei Arayos) for all Halachic matters.)
