The term "Kanyapayana" refers to a form of political alliance through marriage diplomacy, literally meaning "giving of daughters in marriage".
According to the Allahabad Pillar Inscription of Samudragupta, composed by his court poet Harishena, several frontier rulers including the Kharaparikas offered tributes, daughters in marriage (kanyapayana), and sought the favor of the Gupta emperor.
This was part of Samudragupta’s southern and frontier policy, where some rulers submitted peacefully, offering tributes and forming alliances, while others were subdued militarily.
