However, it was not just in the architecture of the Old Conquests of Ilhas, Bardez and Salcete that there was a Bijapuri influence. Portions of what would come to be called the New Conquests continued to be a part of the Bijapuri Sultanate until they were integrated into the Estado da Índia. It is to the Indo-Persian administrative organization followed by the Bijapur sultanate that we owe the identity of such identities as that of Antruz Mahal. Further, the Christian history of the New Conquests owes as much to the Bijapuri Sultanate as it may to the Portuguese state. It was under leave from the Sultan, in about 1639, that Mateus de Castro, the ambitious native cleric who chafed under the Portuguese, received permission to build churches in Bicholim, Banda, and Vengurla.
