The hearth area of Buddhism is widely recognized to be in India. Buddhism originated in the 5th to 4th century BCE with the teachings of Siddhartha Gautama (Buddha) in the northeastern region of Indian subcontinent, particularly in areas that are now part of modern-day India and Nepal.

While Buddhism eventually spread to other countries in Asia such as Thailand, Indonesia, Japan, and China, its foundational roots are firmly planted in India. The major sites associated with the early life of Buddha, including Lumbini (his birthplace), Bodh Gaya (where he attained enlightenment), Sarnath (where he delivered his first sermon), and Kushinagar (where he passed away), are all located in India.
