Jeddah, alternatively transliterated as
Jedda,
Jiddah or
Jidda, is a port city in Makkah Province, Saudi Arabia, located along the Red Sea coast in the Hejaz region. Jeddah is the commercial center of the country. 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 to the holy city of Mecca for Islamic pilgrimage. 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.
