1975 Algiers Agreement

The 1975 Algiers Agreement, also known as the Algiers Accord and the Algiers Declaration, was signed between <a href="/facts/Pahlavi_Iran/WqU7j2W8">Iran</a> and <a href="/facts/Ba%27athist_Iraq/lbHnSQBz">Iraq</a> to settle any outstanding territorial disputes along the <a href="/facts/Iran%E2%80%93Iraq_border/NtBnXj8y">Iran–Iraq border</a>. Mediated by <a href="/facts/Algeria/UXDF4Tj6">Algeria</a>, it served as the basis for additional bilateral treaties signed on 13 June 1975 and 26 December 1975. The territorial disputes in question concerned Iraq's <a href="/facts/Shatt_al-Arab_dispute/x8L9UzWF">Shatt al-Arab</a> and Iran's <a href="/facts/Arab_separatism_in_Khuzestan/PnY4NoXL">Khuzestan Province</a>, and Iraq had wished to negotiate to end Iran's support for the then-ongoing <a href="/facts/Second_Iraqi%E2%80%93Kurdish_War/axvF8V8H">Iraqi Kurdish rebellion</a> after suffering a military defeat in the <a href="/facts/1974%E2%80%9375_Shatt_al-Arab_conflict/V8XRwbA8">1974–1975 Shatt al-Arab conflict</a>. On 17 September 1980, shortly after the <a href="/facts/Iranian_Revolution/frTYhJ0F">Iranian Revolution</a>, the Iraqi government abrogated the treaty in light of another series of cross-border clashes between the two countries. On 22 September 1980, the treaty was completely voided with the <a href="/facts/Iraqi_invasion_of_Iran/MB5YVo50">Iraqi invasion of Iran</a>, which triggered the eight-year-long <a href="/facts/Iran%E2%80%93Iraq_War/DqD7W8vd">Iran–Iraq War</a>.
Today, friction continues on the two countries' border despite the treaty remaining binding under international law (per <a href="/facts/United_Nations_Security_Council_Resolution_619/lgClgJ8s">UNSC Resolution 619</a>), and the detailed boundary delimitation is still de jure in force since it was signed in 1975 and ratified in 1976 by both Iran and Iraq.
