⚔️ Foreign Invasions
Before we dive into Jainism and Buddhism, it is important to understand the geo-political backdrop of 6th–3rd century BC India. Iran and Greece both invaded the North-West, leaving lasting impacts on Indian coinage, art, trade routes and cultural exchange. These invasions also helped open India to the wider ancient world.
🇮🇷 Iranian Invasion
Cyrus of Persia — first foreign conqueror; destroyed city of Capisa
Successors Darius I and Xeres invaded North-West India
Cultural exchange: Kharoshti script from Iran; bell-shaped capitals in sculpture
🏹 Alexander's Invasion
Alexander — conquered Kabul in 328 BC; entered India via unguarded Khyber Pass
Ambhi (Taxila) submitted; first strong resistance from Porus
Battle of Hydaspes — on bank of Vitasta (Jhelum); Alexander defeated Porus but restored his kingdom
Army refused to cross Beas → forced to retreat; placed NW India under Selucus Nikator
Remained in India 19 months (326–325 BC); died in Babylon 323 BC at age 33
Indians learnt from Greeks: coinage, astronomy, Gandhara School of sculpture
🪷 Jainism
Jainism is one of India's oldest religions, predating Buddhism. It was founded to protest the excessive ritualism and caste hierarchy of Brahmanical religion. Its 24 Tirthankaras (spiritual teachers) form a lineage of enlightened beings, with Vardhaman Mahavira being the most historically significant as the reformer who gave Jainism its final shape.

☸️ Buddhism
Buddhism emerged in the 6th century BC as a revolutionary response to the suffering and inequality of the time.

It eventually spread across all of Asia.
Founded by Gautama Buddha (Sakyamuni/Tathagat); originally known as Siddhartha
