Pillai, meaning Prince, is a title of nobility which can either refer to a ruling chief, members of the nobility, or junior princes of the royal family historically ranked immediately below the king. The oldest lineages of Pillais include not only Kshatriyas but also brahmins who took up the sword. From the early modern period, the title also came to be bestowed upon Savarna subjects by the King of Travancore for services military or political, most of whom were of Nair origin.
