According to local legends and myths, the last king of the Later Chera dynasty divided his kingdom among his various chieftains and governors.
Kottayam, Chenganacherry, Thiruvalla, Kanjirappally and some places of high range were included in Thekkumkoor kingdom.
It was this Nair Lord family who had great influence on the king and inspired him to donate the Kallooppara sub-division to the Edappally dynasty.
The Edappally Dynasty has the history of elevation of a temple priest to the royal position of a King.
The famous St. Marys Valiyapally known as Kalloopparapally constructed with permission of Edappally Raja in AD 1339 (Karkidakam 3 Kollavarsham 515).
As Zamorin could not wage battles against a Brahmin, in 1536, the first sacking of Edapally took place under Martin D'Souza.
One of the earliest local history initiatives centred on the study of the relationship between Edappally church and Elangalloor Swaroopam.
