Indian nationalism developed as a concept during the Indian independence movement which campaigned for independence from British rule. Indian nationalism is an instance of territorial nationalism, which is inclusive of all of the people of India, despite their diverse ethnic, linguistic and religious backgrounds. It continues to strongly influence the politics of India and reflects an opposition to the sectarian strands of Hindu nationalism and Muslim nationalism.
India has been unified under many emperors and governments in history. Ancient texts mention India under emperor Bharata and Akhand Bharat, these regions roughly form the entities of modern-day greater India. The Mauryan Empire was the first to unite all of India, and South Asia (including much of Afghanistan). In addition, much of India has also been unified under a central government by empires, such as the Gupta Empire, Rashtrakuta Empire, Pala Empire, Mughal Empire, Vijayanagara Empire, Maratha Empire, British Indian Empire, etc.
India's concept of nationhood is based not merely on territorial extent of its sovereignty. Nationalistic sentiments and expression encompass that India's ancient history, as the birthplace of the Indus Valley Civilization and Vedic Civilization, as well as four major world religions – Hinduism, Buddhism, Jainism and Sikhism. Indian nationalists see India stretching along these lines across the Indian Subcontinent.
India today celebrates many kings and queens for combating foreign invasion and domination,[7] such as Shivaji of the Maratha Empire, Rani Laxmibai of Jhansi, Kittur Chennamma, Maharana Pratap of Rajputana, Prithviraj Chauhan and Tipu Sultan. The kings of Ancient India, such as Chandragupta Maurya and Ashoka of the Magadha Empire, are also remembered for their military genius, notable conquests and remarkable religious tolerance.
