There is some ambiguity regarding the exact course of events that led to the establishment of Eradi's rule over Kozhikode, their later seat. Some historians are of the view that the Eradi was in fact a favourite of the last Kodungallur Chera king as he was at the forefront of the battles with the Chola–Pandya forces in south Kerala. The Eradi seems to have led the Chera army to victory. The king therefore granted him, as a mark of favour, a small tract of land on the sea-coast in addition to his hereditary possessions [Eralanadu province. The Eradis subsequently moved their seat to the coastal "marshy lands" and established the city of Kozhikode.
