Families from where Maharajas got married were known as
Ammaveedus. It is believed that when the then Travancore King, Maharajah Sree Karthika Thirunal Dharamaraja shifted capital from Padmanabhapuram to Thiruvananthapuram, he brought along his four wives who belonged to the places namely Vadasseri, Nagercoil, Arumana, and Thiruvattar. The new houses, referred to as Ammaveedus (ancestral homes of Ammachis) were constructed in the new capital and were named Arumana Ammaveedu, Vadasseri Ammaveedu, Nagercoil Ammaveedu, Thiruvattar Ammaveedu. The Maharajah also passed a rule that all the Royal male members should only marry from one of the above-mentioned four Ammaveedus. This gave social prominence to the Ammachis as well as their homes. The Kings of Travancore traditionally took wives from Ammaveedus and the Consorts, known as
Ammachis would get the additional title of
Panapillai Amma. If at all another lady from outside the Ammaveedu's was to be married to the King, she would be adopted to one of the Ammaveedus first and then wed to the King. This was the case in the marriage of Maharajah
