When Upendranarayana breathed his last, his successor Debendranarayana was only four years old. The chief queen, with the support of royal courtiers, crowned Debendranarayana as successor. Coins were struck in the name of minor king. The coins of Debendranarayana are particularly common, and are found quite often in Bhutan. This is consistence with the fact that during his reign the influence of the Bhutanese in the affairs of Coochbehar increased. As per a previous treaty, a representative of Bhutan, together with an armed escort was based locally and had a significant role in the administration of the state. In addition important Bhutanese chiefs visited the boarders of Coochbehar and offered presents in kind to the Koch king.
