He conquered neighbouring kingdoms Attingal Desam, Ilayidam Swaroopam, Ambalappuzha, Thekkumkoor and Vadakkumkoor, thereby extending the borders of his empire. He defeated Ettuveettil Pillais, a group that conpired to undermine his governance. Marthandavarma introduced military reforms of European style and annual budget system.
