Tam: விருதுநகர் virutunakar
‘Victory Town’ City/District, Tamil Nadu
From Tam: virutu , ‘banner’, ‘trophy’, ‘badge of victory’; and Skt: nagar, ‘city’.
The town clearly commemorates a victory of some sort. But it is not clear what it was or when.
Legends tell tales of a warrior who had banners from his victorious battles. He threw down a challenge to the town for single comabat which one of its citizens accepted. The warrior was killed in the duel and his flags were seized.
Virudhunagar has a gender ratio of 101.4 females for every 100 males, way above the national average of 92.9, and comparable to Western ratios. A cause for flag-waving, surely.
