After Nader's death, the Dutch continued to have good commercial relations in Bushehr, until the British made their debut in Bushehr in 1763 by a contract they signed with Karim Khan of the Zand dynasty. By then, the city of Bushehr had become Iran's major port city in the Persian Gulf. By the Qajar era, Britain, Norway, Russia, Italy, France, Germany, and the Ottomans had diplomatic and commercial offices there, with Britain steadily gaining a foothold in the area. Close to 100 British ships are reported to have docked at the port city every year during the Qajar era.
