Hinduism is the world’s oldest religion, according to many scholars, with roots and customs dating back more than 4,000 years. Today, with more than 1 billion followers, Hinduism is the third-largest religion worldwide, after Christianity and Islam. Roughly 94 percent of the world’s Hindus live in India. Because the religion has no specific founder, it’s difficult to trace its origins and history. Hinduism is unique in that it’s not a single religion but a compilation of many traditions and philosophies: Hindus worship a number of different gods and minor deities, honor a range of symbols, respect several different holy books and celebrate with a wide variety of traditions, holidays and customs. Though the development of the caste system in India was influenced by Hindu concepts, it has been shaped throughout history by political as well as religious movements, and today is much less rigidly enforced. Today there are four major sects of Hinduism: Shaivism, Vaishnava, Shaktism and Smarta, as well as a number of smaller sects with their own religious practices.
