Knanaya
Historian of medieval India and Northist priest Pius Malekandathil argues that the two-wives legend was simply a creation of rivalry between the Middle Eastern migrant Knanaya and the Native St. Thomas Christians. Malekandathil expresses that the story originated in the medieval era due to the two ethnic groups of Christians asserting socioeconomic dominance over the other. Furthermore, Malekandathil notes that the two-wives legend is not the accepted tradition among the people of Kerala but instead that the indigenous Saint Thomas Christians got the appellation "Northists" because they were initially located on the northern part of the city of Cranganore, while the migrant Knanaya under the leadership of Thomas of Cana were given the southern side of the city which led to the generic title of "Southists".
