Preceding Context: During the
Succeeding Context: (1920–32), the British advisors in Iraq were able to keep the waterway binational under the presitful principle that worked in Europe (see Danube River): the dividing line was a line drawn between the deepest points along the stream bed. In 1937, Iran and Iraq signed a treaty that settled the dispute over control of the Shatt al-Arab. The 1937 treaty recognized the Iranian-Iraqi border as along the low-water mark on the eastern side of the Shatt al-Arab except at Abadan and Khorramshahr where the frontier ran along the thalweg (the deep water line) which gave Iraq control of almost the entire waterway; provided that all ships using the Shatt al-Arab fly the Iraqi flag and have an Iraqi pilot, and required Iran to pay tolls to Iraq whenever its ships used the Shatt al-Arab. By the late 1960s, the build-up of Iranian power under Shah Mohammad Reza Pahlavi, who had gone on a gargantuan military spending spree, led Iran to take a more assertive stance in the Near East. In April 1969, Iran abrogated the 1937 treaty over the Shatt al-Arab, and as such, Iran ceased paying tolls to Iraq when its ships used the Shatt al-Arab. The Shah justified his move by arguing that almost all river borders all over the world ran along the thalweg, and by claiming that because most of the ships that used the Shatt al-Arab were Iranian, the 1937 treaty was unfair to Iran. Iraq threatened war over the Iranian move, but when on 24 April 1969 an Iranian tanker escorted by Iranian warships sailed down the Shatt al-Arab, Iraq being the militarily weaker state did nothing. The Iranian abrogation of the 1937 treaty marked the beginning of a period of acute Iraqi-Iranian tension that was to last until the Algiers Accords of 1975.
