In practice, however, the Portuguese only ruled the coast lands and the Sinhala Kings of Kandy remained paramount in the interior of the island. Portuguese coinage struck in, or for, Ceilao all appears to postdate the declaration of Philip's suzerainty in 1597. Subsequent Captains-general recorded to have issued money are D. Jeronymo de Azevedo (1594-1612) and D. Constantino de Sa (1619-1630). Local striking was ordered to cease in 1634, but had been resumed by 1640 when dated 'gridiron' tangas were being struck. Local minting continued until at least 1645, but from about 1642 most silver coin destined for use in Ceilao was struck at Goa. Circulation of St. John type silver coins was forbidden at Goa in 1650 when replaced by the 'Cross of Christ' type silver coin. The Goa mint continued strikings of St. John issues for use in Ceilao until 1653.
In 1638 the King of Kandy, Rajasinga II, called on the Dutch for help against the Portuguese and in 1655 the last Portuguese fortress on the island feil into Dutch hands.
