History
Iran occupies the great plateau between the Caspian Sea and the Persian Gulf, a land bridge between the Middle East, Central Asia, and South Asia that has shaped world history for more than 2,500 years. Heir to the ancient Elamite and Achaemenid Persian empires, it is one of the world's oldest continuous civilizations, and its official language, Persian (Farsi), is among the oldest literary languages still spoken. Roughly 89.2 million people (2025 est.) live in a theocratic republic proclaimed on 1 April 1979, governed from Tehran, a metropolis sprawling beneath the snow-capped Alborz range. The terrain is dramatic: the Zagros Mountains wall off Mesopotamia to the west, the volcanic cone of Mount Damavand — the highest peak in the Middle East — rises above the Caspian littoral, and vast salt deserts fill the interior. The economy, measured at about $1.486 trillion in purchasing-power terms (2024 est.), rests on some of the world's largest oil and natural gas reserves, with China taking roughly 35% of exports. Persians form the largest ethnic group, joined by Azeris, Kurds, Lurs, Baloch, Arabs, and Turkmen in a mosaic as old as the plateau itself.
Tehran's urban core is home to about 11,142,683 people.
That's bigger than London, Paris, Madrid and Toronto — each a great world city in its own right.
Among the world's megacities, though, it's one of many — the giants of Asia and Latin America run larger still:
More people live in Tehran than in the entire nation of Sweden, Greece, Portugal or Israel.
Iran's Olympic ledger is anchored in the combat sports. Freestyle wrestler Gholamreza Takhti won gold at Melbourne 1956 with silvers either side, and successors like Hassan Yazdani — gold at Rio 2016, silver at Tokyo — have kept Iran among the world's elite wrestling nations. Super-heavyweight lifter Hossein Rezazadeh took back-to-back golds at Sydney 2000 and Athens 2004 with world-record totals; taekwondo fighter Hadi Saei collected golds in 2004 and 2008 to become Iran's most decorated Olympian, and Kimia Alizadeh's Rio 2016 bronze made her the first Iranian woman on an Olympic podium. In football, Team Melli has qualified for six FIFA World Cups; Ali Daei's 109 international goals stood as the men's world record until 2021, and the 2-1 victory over the United States at France 1998 remains the national team's most celebrated night. Sitting volleyball adds a Paralympic dynasty, and the men's volleyball team has beaten the world's best in top-flight international play.
