The Plains of India are considered to be the country’s heartland. The Ganges (Ganga in Hindi) and Yamuna rivers flow through this region. Major events of India’s history took place here. This region contains the large and politically significant states of Uttar Pradesh, Madhya Pradesh and Bihar, and the country’s capital, New Delhi. It is the large space of level land that is made by the Ganges River in the northern parts of modern India and the border surrounding areas of the Himalayas. It is an important part of the countries of the Republic of India, Nepal, and Bangladesh. Its space of about 700,000 square kilometers or 270,000 square miles is the home of about 1 billion persons (about one in every seven persons alive today). Its western edge is the Thar Desert; its northern edge is the Himalaya Mountains, the highest mountains on Earth; its eastern edge is the Ganges Delta of Bengal, the largest River delta in the world; and its southern edge is made by the Vindhya and Satpura mountains and Chota Nagpur plateau of middle India.
