Starting in the early 19th century, Gaza was culturally dominated by neighboring Egypt; Muhammad Ali of Egypt conquered Gaza in 1832. American scholar Edward Robinson visited the city in 1838, describing it as a "thickly populated" town larger than Jerusalem, with its Old City lying upon a hilltop, while its suburbs laid on the nearby plain. The city benefited from trade and commerce because of its strategic position on the caravan route between Egypt and northern Syria as well as from producing soap and cotton for trade with the government, local Arab tribes, and the Bedouin of Wadi Arabah and Ma'an. The bazaars of Gaza were well-supplied and were noted by Robinson as "far better" than those of Jerusalem. Robinson noted that virtually all of Gaza's vestiges of ancient history and antiquity had disappeared due to constant conflict and occupation. By the mid-19th century, Gaza's port was eclipsed by the ports of Jaffa and Haifa, but it retained its fishing fleet.
