Afonso de Albuquerque re-established Portuguese dominance at Hormuz (a critical Gulf entrepôt), consolidating a strategic position that later became the main flashpoint in Safavid–Portuguese conflict and Safavid outreach to other European rivals of Portugal.
English merchant-diplomat Anthony Jenkinson visited the Safavid realm during Elizabeth I’s reign, an early documented English contact that later Safavid–English diplomacy would reference when seeking anti-Ottoman partners and trade openings.
Shah Abbas I sent a diplomatic mission (with Hossein Ali Beg Bayat and the English adventurer Anthony Sherley) to seek a European alliance against the Ottoman Empire—an important early-modern attempt to align strategic interests across religious and political divides.
During the 1599–1602 mission, Safavid representatives visited the court of Holy Roman Emperor Rudolf II at Prague, reflecting the embassy’s high-level engagement with Habsburg power centers amid shared anti-Ottoman concerns.
Safavid forces under Allahverdi Khan seized Bahrain from the Portuguese, signaling a more assertive Safavid posture in the Persian Gulf and setting the stage for subsequent anti-Portuguese cooperation with other European powers.
Shah Abbas I dispatched Mehdi Qoli Beg as a special ambassador to Prague, aiming to sustain Safavid–Habsburg diplomatic coordination during the broader strategic contest with the Ottoman Empire.
Sir Robert Sherley departed Safavid Iran with authority to negotiate with European rulers for alliances and support against the Ottomans, illustrating how the Safavids leveraged European intermediaries to navigate confessional and commercial politics.
A second major Safavid mission (often associated with Robert Sherley) visited multiple European courts—including Kraków, Prague, Rome, Madrid, and London—seeking anti-Ottoman alignment and strengthening Safavid visibility in European diplomacy.
The Treaty of Serav ended the 1616–1618 Ottoman–Safavid war, temporarily stabilizing the western frontier and influencing how urgently the Safavids pursued European military partnerships versus commercial diplomacy.
Portuguese forces under Rui Freire de Andrade fought the English East India Company off Jask; the English victory highlighted growing Anglo–Portuguese maritime rivalry near Safavid waters and foreshadowed English–Safavid cooperation against Portugal.
Portuguese troops commenced construction of a fort on Qeshm (near Hormuz), an escalation widely treated as a casus belli by Shah Abbas I and a direct trigger for the ensuing Safavid–Portuguese war in which the English would become key partners.
Safavid forces, supported by ships of the English East India Company, captured the Portuguese position on Qeshm—an operational prelude that tightened military cooperation and cleared the way for the attack on Hormuz.
A combined Safavid–English expedition captured Hormuz after a ten-week siege, ending the Portuguese stronghold there and reshaping Gulf trade by enabling expanded Safavid commercial ties with England via new mainland ports.
After years of raids and countermeasures following Hormuz’s fall, hostilities in the Portuguese–Safavid War moved toward settlement around 1629–1630, with arrangements that permitted renewed Portuguese trading presence under constrained terms alongside English competition.
Portugal’s Estado da Índia and the English East India Company concluded the Convention of Goa, reducing direct Anglo–Portuguese hostilities in Asia; this altered the diplomatic-commercial environment in which Safavid Gulf policy interacted with European maritime powers.
