Delhi is the capital city of India, located in the center of the country. As the capital, Delhi represents all of India but faces challenges in uniting its diverse population and history. Delhi has a population of over 16 million and evidence of Hindu, Christian, Islamic, and Buddhist architecture due to its long history as the center of several empires. However, the city also struggles with extremes of wealth and poverty, and religious and cultural divisions. One success at representing unity is the Baha'i Temple, which brings together different architectural styles. But overall, achieving a cohesive Indian identity remains an ongoing challenge.
