 Originally, the Palakkad Iyers came from the 19 villages chronicled by William Logan (author) in his 1887 guide to Malabar District.However, today the term covers Iyers from a broader territory.During the rule of Travancore kings, many Iyers (Tamil Brahmins) were invited to Thiruvananthapuram for administrative requirements of Travancore kingdom and for participating in rituals related to Padmanabhaswamy Temple.
