Jeddah is a city in the Hejaz region of western Saudi Arabia and the country's commercial center. It is not known when Jeddah was founded, but Jeddah's prominence grew in 647 when the Caliph Uthman made it a travel hub serving Muslim travelers going for Islamic pilgrimage to the holy city of Mecca. Since those times, Jeddah has served as the gateway for millions of pilgrims who have arrived in Saudi Arabia, traditionally by sea and recently by air. With a population of about 4,697,000 people as of 2021, Jeddah is the largest city in Makkah Province, the largest city in Hejaz, the second-largest city in the Saudi Arabia (after the capital Riyadh), and the ninth-largest in the Middle East. It also serves as the administrative centre of the OIC. Jeddah Islamic Port, on the Red Sea, is the thirty-sixth largest seaport in the world and the second-largest and second-busiest seaport in the Middle East (after Dubai's Port of Jebel Ali).
