Go back 5,000 years and the world looks completely different. There are no nations, no sanctions, and no superpowers anywhere. Merchants from the Indus Valley crossed the Iranian plateau carrying goods, ideas, and culture freely. Furthermore, archaeologists later found identical painted pottery and seals in both Mohenjo-Daro and Susa, Iran. Additionally, these findings confirmed that two great civilisations had already chosen each other deliberately. Consequently, this ancient connection predated every modern diplomatic framework by thousands of years. Therefore, the India-Iran relationship did not begin in 1950 — it began in prehistory.
They Even Shared the Same Gods
Trade was only one layer of this extraordinary ancient bond. Furthermore, the connection ran deeper, all the way to the sacred rituals of both civilisations. Ancient Indo-Aryan and Old Iranian cultures shared traditions found in both the Rig Veda and the Avesta simultaneously. Additionally, the sacred plant India called Soma, Iranians called Haoma. Moreover, fire worship existed uniquely in both regions and nowhere else across the entire Indo-European world. Consequently, these two cultures shared not just commerce but their most sacred spiritual practices. Therefore, this was not merely a trading relationship, it was a civilisational kinship running through the soul of both nations.
Persia Carried India’s Wisdom to the Entire World
For centuries, Persian served as the court language of India’s most powerful empires. Furthermore, Prince Dara Shukoh ordered translations of the Upanishads and Yoga Vashistha into Persian directly. Additionally, those translated texts then crossed oceans and eventually reached the libraries of Europe. Moreover, Goethe and Schopenhauer both read India’s deepest philosophy through Persian translations in Latin. Consequently, Iran served as the bridge that carried Indian wisdom to the entire Western intellectual world. As Iran’s own representative later confirmed, “Even at the university, we studied philosophical books of India.” Therefore, Tehran was effectively India’s first and most important global publisher of knowledge.
Modern India Chose Iran Early and Ambitiously
When India gained independence in 1947, it remembered this ancient connection immediately. Furthermore, India formally established diplomatic ties with Iran on 15 March 1950 without hesitation. Additionally, PM Vajpayee signed the landmark Tehran Declaration during his visit in 2001. Moreover, PM Modi stood in Tehran in 2016 and called the relationship a “civilisational connect, contemporary context” proudly. Consequently, bilateral trade reached USD 12.89 billion in 2016-17, reflecting genuine economic depth. Furthermore, India signed a historic agreement to develop Chabahar Port in May 2016, giving India direct access to Afghanistan and Central Asia entirely bypassing Pakistan. Therefore, the ancient friendship had finally found a concrete and powerful modern strategic shape.
Oil, Gas and a Billion-Dollar Strategic Dream
The ambition behind India-Iran cooperation extended far beyond Chabahar Port alone. Furthermore, Iran holds the world’s second largest natural gas reserves, making it strategically invaluable. Additionally, before sanctions intensified, Iran served as India’s second largest crude oil supplier consistently. Moreover, Indian companies expressed willingness to invest nearly USD 20 billion in Iran’s energy sector ambitiously. Furthermore, India committed USD 1.6 billion toward the Chabahar-Zahedan railway project directly. Additionally, the INSTC corridor connecting Mumbai to Moscow through Tehran promised to cut cargo transit time by half. Consequently, India had genuinely found its most promising gateway to Eurasia and Central Asian markets. Then Washington made its decisive move against Iran.
Sanctions Cracked What History Could Not Break
In May 2018, the United States withdrew from the Iran nuclear deal and reimposed severe sanctions. Consequently, India stopped importing Iranian crude oil after May 2019 under enormous American pressure. Furthermore, bilateral trade collapsed dramatically from USD 13.53 billion in 2018-19 to just USD 1.4 billion in 2019-20. Additionally, Iran’s Supreme Leader Khamenei publicly criticised India over Kashmir in 2019, the Delhi riots in 2020, and Muslim treatment in 2024. Moreover, India summoned the Iranian ambassador twice and called his remarks “completely unacceptable” each time. Consequently, two ancient friends now stood on opposite sides of other people’s geopolitical battles. Therefore, the relationship was cracking under pressure it had never faced before in 5,000 years.
Khamenei Dies – India Chooses Silence
February 28, 2026 brought the most dramatic moment in recent India-Iran relations history. US and Israeli strikes killed Iran’s Supreme Leader Ali Khamenei on that day. Furthermore, the entire world reacted within hours with strong and decisive statements. However, India did not react immediately or clearly. Additionally, PM Modi’s first statement came nearly a day later and focused on UAE rather than Iran. Moreover, India offered condolences on Khamenei’s death only days after his death was officially confirmed. Consequently, experts called India’s silence deliberate and carefully calculated. Therefore, India chose to balance Washington, Tel Aviv, Gulf allies, and Tehran simultaneously through strategic diplomatic silence.
5,000 Years Later – The Friendship Survives Anyway
Despite every crack, sanction, and diplomatic silence, the relationship refuses to die completely. Furthermore, Iran called External Affairs Minister Jaishankar four times during the 2026 Middle East crisis urgently. Additionally, India actively negotiates safe passage for over 20 Indian tankers through the Strait of Hormuz currently. Moreover, Chabahar Port still stands and the INSTC corridor still moves goods between nations. As Iran’s own representative stated powerfully, “The history goes back 3,000 years, before the emergence of Islam.” Consequently, this relationship carries a weight that no sanction or superpower can simply erase overnight. Therefore, India and Iran remain complicated, pressured, tested, but fundamentally and permanently alive. Because 5,000 years of shared civilisation does not disappear for anyone.
