History of Kerala: How did the Kingdom of Travancore originally form?

KIngdom of Travancore began with Marthanda Varma, who inherited the kingdom of Venad (Thrippappur), and expanded it into Travancore during his reign (1729–1758). He expanded the kingdom of Venad, through a series of military campaigns, from Kanyakumari in the south to the borders of Kochi in the north during his 29-year rule.He signed a treaty with the British East India Company and with their help, destroyed the power of the eight feudal land lords called Ettuveetil Pillamar and "Ettara Yogam" who supported the Thampi sons of the previous king of Venad, Rajah Rama Varma.  After achieving internal stability in his kingdom, Marthanda Varma set  out to conquer the neighbouring kingdoms. In successive battles, Marthanda Varma defeated and absorbed the kingdoms right up to Cochin kingdom including Attingal, Kollam, Kayamkulam, Kottarakara, Kottayam, Pandalam, Poonjar and Chempakassery.
