India historical timeline

Origins

India is home to one of the world's oldest continuous civilizations, dating back to the Indus Valley Civilization (c. 3300-1300 BC), one of the earliest urban societies on Earth, and the birthplace of four major world religions -- Hinduism, Buddhism, Jainism, and Sikhism -- each still practiced by millions today.

Turning points

The Maurya Empire under Ashoka spread Buddhism across Asia; the Mughal Empire's 16th-19th century rulers left behind some of India's most iconic architecture, including the Taj Mahal, built by Shah Jahan in the 1630s-40s. British colonial rule, formalized after 1858, dominated India for nearly a century before independence on August 15, 1947 -- a moment inseparable from the traumatic Partition of India and Pakistan, which displaced an estimated 15 million people.

Influential people

Ashoka embraced Buddhism after a brutal conquest and spread it across Asia; Shah Jahan built the Taj Mahal as a mausoleum for his wife; and Mahatma Gandhi's philosophy of nonviolent resistance (satyagraha) led the independence movement that ended British rule.

Cultural evolution

Successive empires and religions layered onto rather than replaced what came before -- Buddhist, Hindu, Islamic, and colonial-era architecture and belief systems still coexist visibly across the country today. Gandhi's independence movement added a distinctly Indian political philosophy to that layering, one that influenced civil rights movements well beyond India's own borders.

Present-day significance

Since independence, India has developed into the world's largest democracy and one of its fastest-growing major economies, continuing to navigate the immense diversity of languages, religions, and regional identities that its long history left behind. Its cultural output -- Bollywood cinema chief among it -- has made it an increasingly central presence on the world stage.
