After the Iraqi Revolution of 1958, a naval base was established at Umm Qasr. The port was subsequently founded in 1961 by the Iraqi ruler General Abdul-Karim Qassem. It was intended to serve as Iraq's only "deep water" port, reducing the country's dependence on the disputed Shatt al-Arab waterway that marks the border with Iran. The port facilities were built by a consortium of companies from West Germany, Sweden and Lebanon, with a railway line connecting it to Basra and Baghdad. The port opened for business in July 1967.
