The erstwhile Kingdom of Cochin was reorganized into Thrissur district and Taluks of North Paravur and Kunnathunad were transferred to that district. Similarly the Cherthala Taluk was transferred into the newly formed Kollam district on 1 July 1949. The High Range division of the erstwhile Travancore was merged with the remaining Taluks of the erstwhile Kottayam division to form the Kottayam district as a part of the inauguration of the new Indian state of Travancore-Cochin on 1 July 1949. The new district of Kottayam at that time contained eight Taluks – Changanassery, Kottayam, Vaikom, Meenachil, Muvattupuzha, Thodupuzha, Devikulam, and Peerumede.
