Introduction
Ancient India and Iran were two of the world’s earliest civilizations. From the Indus Valley Civilization to the Maurya and the Gupta Empires, and from the Elamite Civilization to the Achaemenid and Sassanian Empires, India and Iran were giants when it came to economy, power & wisdom for about 3000 years. They also shared many similarities with respect to religion, language, and culture. This blog gives a brief comparative study between the two nations and tries to understand the similarities between the two ancient neighbours and their legacies.
Linguistic Relationships: A Journey through Vedic Sanskrit and Avestan
The earliest texts found in the two nations are the Vedas and the Avesta. The language through which they are written, i.e., Vedic Sanskrit and Avestan, interestingly shares a good amount of similarities between them. Some of the similarities in their vocabularies are given as follows-
| English Word | Vedic Sanskrit | Avestan |
| Sacrificial Ritual | Yajna | Yasna |
| Sacrificial Drink | Soma | Haoma |
| Gold | Hiranya | Zaranya |
| Honorable Man | Aryaman | Airyaman |
| Army | Sena | Haena |
| Horse | Asva | Aspa |
| Man | Nara | Nar |
| Cow | Go | Gav |
| Earth | Bhumi | Bumi |
| Animal | Pasu | Pasu |
| Mind | Manas | Manah |
| Is | As | Asti |
| River | Sindhu | Hendu / Hindu |
From these words, we can predict that both Vedic Sanskrit and Avestan were perhaps sister languages that may be both descending from a Proto Indo-Iranian Language. Even the people living in both ancient India and Iran referred to their land as Aryavarta and Airyanem Vaejah, both meaning the land of the Aryas or Aryans in Sanskrit and Avestan. The word Arya means honorable in both languages and has nothing to do with race, unlike that which was adopted and abused by the Nazis. Even the hymns of the Vedic Samhitas and the Avestan Gathas sound quite similar when listened to carefully during Hindu and Zoroastrian rituals.
Today the heirs to these languages i.e., Modern Indo Aryan Languages like Hindustani, Bengali, Punjabi, Marathi, Gujarati etc. and Modern Iranian languages like Persian, Pashto, Kurdish, Balochi etc. are spoken in large numbers in countries like India, Pakistan, Bangladesh, Nepal, Sri Lanka, Iran, Afghanistan, Tajikistan and Iraq covering a population of roughly 1,700,000,000 people.

Religious Relationships: Hinduism & Zoroastrianism- The Parallels & The Antiparallels
The Ancient Vedic Religion was a nature-based, polytheistic faith and is the foundation of modern Hinduism. The Rig Veda, the oldest Indian text, starts by highlighting Agni, the god of fire, as the priest of the gods. Agni purifies negativity and leads the Yajna, a sacrificial ritual. During these rituals, people consumed a drink called Soma.
The Ancient Iranian Religion also practiced polytheism before the prophet Zarathustra. Fire is important in Iranian religions, where it is called Atar or Atash and symbolizes purity and truth. Atar represents Ahura Mazda, the main god, and is vital for rituals known as Yasna, along with a sacrificial drink called Haoma.
In the Vedic religion, gods are called Devas, and demons are known as Asuras. Important Vedic gods includeIndra (the god of rain and thunder, and king of the gods), Agni (the god of fire), Varuna (an Asura associated with balance and order, later linked to the seas), Vayu (the god of wind), Savitr (also called Surya, the sun god), Mitra (the god of the morning sun and friendships), and Yama (the god of the underworld and justice).
In the Ancient Iranian faith, gods are called Ahuras, while demons are called Daevas. Key deities include Ahura Mazda (the king of the gods), Mithra (the god of the rising sun and agreements), Atar (the god of fire), Vayu (the god of wind), Anahita (the goddess of water and fertility), Rashnu (the god of wisdom and justice), and Verethragna (the god of war and victory).
Ancient Hinduism and Zoroastrianism show how their deities often represent opposing views; gods in one tradition are seen as demons in the other. There are also similar names and roles among some deities (for instance, Mitra-Mithra, Vayu-Vayu, and both Indra and Verethragna are linked to defeating a cosmic demon called Vritra).
The two religions took different paths over time. Hinduism shifted from nature worship to include gods related to philosophical ideas, such as Vishnu (the protector of life), Shiva (the destroyer of worlds), and Shakti (representing cosmic feminine energy). It also has the concept of Nirguna Brahman, a god without qualities.
In contrast, Zoroastrianism changed from worshiping many gods to focusing on one main god, Ahura Mazda, with other gods becoming subordinate. Eventually, it embraced monotheism where Ahura Mazda is considered the only god, opposite Angra Mainyu, a negative force, reflecting a dualistic way of thinking. After the Muslim conquest in Persia around 700-800 CE, Zoroastrianism began to decline. Many followers fled to India, where they are known as Parsis. Likewise, Hinduism faced challenges from Turkic Muslims in the 1300s and European colonizers in the 1750s, impacting its beliefs.
Today, about 1.2 billion Hindus live in countries like India, Nepal, Mauritius, Fiji, and Guyana. Around 120,000 Zoroastrians reside mainly in India, Iran, the USA, and Canada.
Geographic & Political Relationships: The sacred lands of Indo-Iranians
The Indian Subcontinent and the Iranian Plateau were home to two key civilizations. They were separated by areas like Bactria (modern-day Northern Afghanistan, Tajikistan, and Southeast Uzbekistan), Gandhara (the Kandahar region of Afghanistan and Northwest Pakistan, including parts of Punjab), and the Indus River (parts of Sindh and Balochistan).
The first contact between these two regions happened around 1000 BCE through trade in the Kabul and Sistan areas. During the reign of the Achaemenid Emperor Cyrus the Great (around 550-530 BCE), parts of India fell under Persian rule, including Gandhara and Northwest Punjab. Later, Emperor Darius the Great sent an expedition to India. His three inscriptions mention relationships with India, including one on the Behistun rock (dating around 518 BCE), identifying Gandhara as one of his subject countries. The Persepolis Inscription lists Punjab as part of the Persian Empire. One inscription from Nagsh-i-Rustam names India as the 24th state in his empire. About one-third of the gold in the Persian Empire came from India, and the Achaemenids also imported rice from India for planting in the Near East. It is believed that the Greek philosopher Pythagoras learned about metapsychosis from India via a Persian. Emperor Xerxes included Indian soldiers in his army when he invaded and conquered Greece.
After Alexander the Great invaded Persia and India, the Persian rule passed to Seleucus Nicator, one of his generals, creating the Seleucid Empire. Emperor Chandragupta Maurya of the Maurya Empire defeated Seleucus and took some Persian territories.
Around 100 BCE, a group of Indianized Persians known as the Indo-Parthians or Pahlavas ruled parts of Northwest India. Both civilizations thrived during the reign of the Kushan Empire, when art forms like Gandhara Art and various knowledge systems developed at Takshashila and Jundishapur in India and Iran, two important centers of ancient learning.
The Sassanian Empire of Iran and the Gupta Empire of India had strong trade relations. The border areas of Gandhara, Kabul, and Sistan became melting pots of cultures, knowledge, and religions. Mani, from an influential Persian family, spread a blended religion called Manichaeism that combined elements of Christianity, Zoroastrianism, and Buddhism, becoming a significant faith in Silk Road cities. The Parthians and Eastern Iranians helped translate Sanskrit texts into Chinese and Tibetan, linking four civilizations.
After the Islamic Conquest of Iran, many Zoroastrians fled to India by sea, landing in Gujarat, which was ruled by the Sisodia clan of the Rajputs.
The Shahnameh by Ferdowsi (1100 CE) narrates that Behramgur, a 5th-century Sassanian king, asked an Indian king named Shangol to send 12,000 musicians to Persia, believed to be the ancestors of the Persian Gypsies. The game of chess is thought to have originated in India as Chaturanga, evolved in Persia as Shatranj, and traveled to the West as Chess.
After the Islamic Conquests, Persia experienced many empires like the Great Seljuks, the Ilkhanates, the Safavids, and the Afsharids. India also witnessed powerful empires during this time, both local and foreign, such as the Palas, Cholas, Delhi Sultanates, Mughals, and Marathas.
Another significant event occurred when Humayun, the 2nd Mughal Emperor, lost to Afghan ruler Sher Shah Suri in the Battle of Chausa in 1539, leading to his escape to Persia. A noteworthy moment was when the Afsharid ruler Nader Shah invaded India in 1738, stealing treasures like the Kohinoor Diamond and the Peacock Throne from the Mughal Court.
There were two main migrations from Iran to India: one during the 7th-8th centuries due to Islamic conquests, leading to the Parsi community, and another during the Qajar Era in the 18th-19th centuries, resulting in the Irani community. Both groups have significantly contributed to India’s development. Notable figures include:
- Homi Jehangir Bhabha (1909-1966), founder of the Indian Nuclear Program
- Ardeshir Godrej (1868-1936), co-founder of the Godrej Group
- Jamsetji Tata (1839-1904), founder of the Tata Group
- Field Marshal Sam Manekshaw (1914-2008), former Chief of the Indian Army and first Indian Field Marshal
- Dadabhai Naoroji (1825-1917), economist, political activist, and the first Asian to be elected to the UK House of Commons, was known for demanding India’s independence publicly.
Today, India and Iran are engaged in various interactions in their present forms as republics.
Conclusion
India and Iran are like two siblings who got lost from each other under various circumstances- Cultural, Political, Geographic, Religious, etc., and now are in their completely own position and going towards their respective ambitions. This blog tries to uphold the civilizational relationships between the two nations and pays homage to the cultural ties across millennia.
