1. 01۱۹۵۱Oil industry nationalizedقوت ارتباط

   Majlis votes to nationalize the Anglo-Iranian Oil Company under Prime Minister Mohammad Mossadegh; National Iranian Oil Company (NIOC) subsequently established.

   چرایی این پیوند: Non-oil ocean-borne imports fell from 658,000 tonnes (1950/51) to 408,000 (1951/52, -38.0%) to 254,000 tonnes (1952/53, -37.7% further, -61.4% cumulative) as the AIOC-enforced international boycott of Iranian oil cut off the hard-currency earnings needed to pay for imports -- a textbook import-compression response to a foreign-exchange crisis. Non-oil EXPORTS rose over the same window (189,000 to 283,000 to 351,000 tonnes, +85.7% cumulative), consistent with merchants pushing non-oil goods (carpets, cotton, dried fruit) harder to earn scarce foreign exchange once oil revenue dried up.

   ملاحظه: Direction is 'mixed' because imports and exports moved in opposite directions -- both consistent with the same underlying foreign-exchange squeeze, but not a simple 'trade collapsed' story.

2. 02۱۹۵۴Consortium Agreementقوت ارتباط

   A consortium of Western oil majors resumes Iranian oil operations under a profit-sharing agreement, ending the nationalization dispute.

   چرایی این پیوند: Imports rebounded from the 1953/54 low of 254,000 tonnes to 460,000 (1954/55, +81.1%) to 581,000 (1955/56) to 891,000 (1956/57) to 1,004,000 tonnes (1957/58) -- exceeding the pre-nationalization 1950/51 level (658,000) by more than 50% within three years, as restored oil revenue under the new Consortium eased the foreign-exchange constraint that had forced import compression during the boycott.
