Shift in Persian Gulf Trade Patterns

Timeline

1. 1516Trade road from Damascus to Aleppo · SyriaAfter the Ottoman occupation of Syria, the Mamluks lost the overland route for transshipping Indian Ocean goods via Aleppo and Damascus. The Levant distribution network on which Gulf merchant communities had relied was cut off, forcing spice prices and route choices to be reorganized.
2. 1516Hormuz · Persian GulfPortuguese-controlled Hormuz became a mandatory port of call for more Indian and Persian goods heading west, and tariff revenues increased. Some merchant ships that had formerly used the Red Sea route now entered the Arabian Peninsula via Muscat and Hormuz, raising the activity of Gulf ports.
3. 1516Basra · BasraAfter taking over Syria, the Ottomans moved to consolidate customs at Gulf gateways such as Basra, attempting to rebuild overland trade routes to the Mediterranean and compete with Portugal for Indian Ocean trade. Gulf merchants faced dual adjustments in tariffs and passes under the change of regimes.
