The Persian or Iranian invasions mark a significant chapter in the history of ancient India, characterized by a series of military campaigns and cultural exchanges between the Indian subcontinent and the Persian Empire. These invasions, led by various Persian rulers, left a profound impact on the socio-political, economic, and cultural landscape of ancient India.
Many Persian invaders targeted the northwestern parts of ancient India. Among these invaders, Cyrus the Great and Darius I, rulers of the Achaemenid Empire, played significant roles. They took advantage of the disunity among Indian kings and rulers to launch multiple invasions between 600 BC and 400 BC.
Cyrus’ invasion
- Cyrus the Great, who founded the Achaemenid Empire, led campaigns to the east of Iran from 558 to 530 BC. It’s believed he also ventured into the Indian borderlands during his conquests.
- Cyrus’s invasion extended to the Indus Valley, where he defeated the Gandhara kingdom. At that time, smaller kingdoms like Gandhara, Madra, and Kamboja were engaged in internal conflicts, which Cyrus exploited to his advantage.
- Some historians suggest that an Indian monarch even sent an embassy to Cyrus, paying him tribute. This implies that Cyrus may have conquered parts of the Indian-Iranian borderland and received acknowledgment from some Indian rulers. The Behistun inscription provides some information about Cyrus’s interactions with Indian territories.
Darius I’s invasion
- Darius I, who succeeded Cyrus and was his grandson, initiated the invasion of the northwestern part of ancient India in 516 BC.
- Darius’s conquest is mentioned in the Hamadan inscription, which includes gold and silver. He invaded India and conquered the Punjab and Sindh regions, as well as parts of the Jhelum river valley.
- Gandhara is noted in the Behistun inscription as a territory of Darius’s empire, possibly inherited from Cyrus. This is supported by Darius’s Susa Palace inscription, which mentions the use of teaks from Gandhara in the construction of the emperor’s palace. Gandhara corresponds to modern-day cities like Peshawar and Rawalpindi in Pakistan.
- Darius I also captured some areas of western Punjab, marking the peak expansion of the Persian Empire during his reign.
Xerxes’ invasion
- Xerxes, the son and successor of Darius I, maintained control over the kingdoms of India within his empire, but he did not extend Persian rule further into the Indian mainland.
- Instead, Xerxes utilized significant numbers of Indian troops, including cavalry, and weapons for his invasion of Greece.
Impact of Iranian Invasion
The Iranian invasions, lasting for about 200 years, brought about significant changes in India politically, socially, economically, and culturally. Here are the effects of these invasions:
- Introduction of the Kharosthi script, similar to Arabic, which is written right to left.
- Influence of Iranian/Persian sculpture-making on Mauryan architecture, seen in the bell shape of Ashoka’s monuments.
- Discovery of the sea route from Persia to India, leading to trade in cotton, indigo, silk, and valuable metals.
- Settlement of a large number of foreigners in India.
- Exchange of Indian culture with Persian scholars and intellectuals, with Indian philosophers and poets traveling to Persia.
- Adoption of the Persian silver coin design by Indian kings for their currency.
- Adoption of certain rituals and ceremonies from Persia by the Indian people.
These Iranian invasions brought both positive and negative changes to India. The Indian subcontinent faced numerous Western invasions from around the sixth century BC to the fourth century BC, primarily due to its wealth and fertile land. These invasions, led by Persian kings and tribal leaders, such as Cyrus, Darius I, Xerxes, and Darius III, had significant social, political, cultural, and economic impacts on India.
