In turn, the commercial dominance of the Persian Gulf attracted the attention of England and Holland, rivals of the Iberian Union and who sought to challenge Spanish-Portuguese control in the region.

At the same time, a fortress was built in the inlet of Gwadar, halfway between Sindh and Hormuz, aiming to wrest control of trade in the area from the Portuguese.

[6] There was thus a clear divergence in the Persian Gulf between Portuguese priorities and Spanish priorities for the region: if the interests of the former were directed towards the Indian Ocean and Asia, Hormuz, due to its political and economic value, was fundamental for the maintenance of the State of India, Castilian interests were clearly oriented towards the Mediterranean, and Hormuz was important because it facilitated the approach to Persia.Despite internal tensions between the ministers of the Crown of Castile and the Crown of Portugal, the Junta of Persia was established at the end of 1618 (made up of 2 members, each, of the Council of Castile and the Council of Portugal, in total) to improve understanding between both Spanish kingdoms) to deal with the question of Hormuz, relating to: the defense of the Iberian possessions in the Persian Gulf against many threats (especially the English and Dutch), the expulsion of the English from the area (or at least to abandon their trade agreements with Persia) and how to treat the Shah's diplomatic relations along with his friendly proposals to grant the Spanish a commercial monopoly on Persian silk on the Cape route.

Its purpose was conciliatory, although due to multiple misunderstandings and ambiguities (in addition to the fact that it was only consultative, while the final decisions were made by the Council of State), it only accentuated Persian warmongering.

[10] An agreement was signed, providing for the sharing of spoils and customs dues at Hormuz, the repatriations of prisoners according to their faith, and the payment by the Persians of half of the supply costs for the fleet.

On the other hand, the Portuguese moved to Muscat (which became their new central base of operations in the Gulf), in turn establishing a trading post in Basra in 1623, at the mouth of the Euphrates River.

The main character of the Luso-Persian war, Rui Freire de Andrada, died in September 1633, and was buried in the church of San Agustín (Muscat).

[7] It is in no way fit for His Majesty's service, for the reputation of his greatness, for the good of that state [of India], nor for his entire monarchy, to admit any nation of Europe to trade in India.However, after many discussions, and with Castilian pressure (who emphasized the impossibility of obtaining the resources and forces to fight the Protestant companies alone in the State of India), finally the Council of Portugal would come to consider an alliance with the English at the time.

[7] They [Lisbon councilors] are very considerate, and this council has always understood it that way, and would never admit the practice of friendship and alliance with any of the nations [of Europe] if it were considered feasible to contrast them all with power and forces of the crown of Portugal alone, which are so limited that even in the times when India flourished and had relations only with the natural kings [Asian governments], the victories and good successes that His Majesty's [Portuguese] vassals "The things they had in those parts were considered miraculous.Although such rapprochement with the English was under the Portuguese condition that the economic damages for the loss of Hormuz be compensated (ideally, the English state was expected to send its ships to help recover Hormuz from what was an illegal act of the English Company).

of the East Indies), something that, for the majority of ministers of the Spanish Council of State, was not worth requesting, since they saw it as unrealistic, in the words of Don Pedro de Toledo "Asking the King of England for things impossible for him would be of little effect to us", since it would not be possible to force the English to give up the vast commercial benefits they were receiving from the Persians.
