Historian Michael Wood traces India's history from the earliest human migrations out of Africa through the Indus Valley cities, the arrival of Sanskrit and the Vedic religions, the Mauryan and Mughal empires, colonial rule, and independence. Wood travels the subcontinent on foot and by boat, visiting sites like Varanasi, the ruins of Vijayanagara, and the Khyber Pass, and talking with priests, scholars, and villagers whose daily rituals still echo practices thousands of years old. He follows the spread of Buddhism from Bihar across Asia, the Islamic sultanates that reshaped the north, and the Portuguese, Dutch, and British traders who turned commercial footholds into an empire. The series treats language and religion as living evidence, tracing how Sanskrit, Tamil, and Persian shaped India's literature and how Hinduism, Buddhism, Jainism, Islam, and Sikhism took root side by side. Shot across the country with local historians and archaeologists as guides, it argues that India's deep past is not separate from its present but still audible in its temples, festivals, and everyday speech.
