criticism for his policies that abandoned his predecessors' legacy of pluralism, citing his introduction of the jizya tax, doubling of custom duties on Hindus while abolishing it for Muslims, destruction of Hindu temples, forbidding construction and repairs of some non-Muslim temples, and the executions of Maratha ruler Sambhaji and the ninth Sikh guru, Guru Tegh Bahadur, and his reign saw an increase in the number and importance of Islamic institutions and scholars. He led many military campaigns against the remaining non-Muslim powers of the Indian subcontinent – the Sikh states of Punjab, the last independent Hindu Rajputs and the Maratha rebels – as also against the Shia Muslim kingdoms of the Deccan. He also virtually stamped out, from his empire, open proselytisation of Hindus and Muslims by foreign Christian missionaries, who remained successfully active, however, in the adjoining regions: the present day Kerala, Tamil Nadu and Goa. The Hindus in Konkan were helped by Marathas, Hindus in Punjab, Kashmir and North India were helped by Sikhs and Hindus in Rajasthan and Central India were helped by Rajputs. Maratha Empire The Hindu Marathas had resisted incursions into the region by the Muslim Mughal rulers of northern India. Under their ambitious leader Chhatrapati Shivaji Maharaj, the Maratha freed themselves from the Muslim sultans of Bijapur to the southeast and, becoming much more aggressive, began to frequently raid Mughal territory. The Marathas had spread and conquered much of central India by Shivaji's death in 1680. Subsequently, under the able leadership of Brahmin prime ministers (Peshwas), the Maratha Empire reached its zenith; Pune, the seat of Peshwas, flowered as a centre of Hindu learning and traditions. The empire at its peak stretched from Tamil Nadu in the south, to Peshawar, present day Khyber Pakhtunkhwa ) in the north, and Bengal in the east. Kingdom of Nepal King Prithvi Narayan Shah, the last Gorkhali monarch, self-proclaimed the newly unified Kingdom of Nepal as Asal Hindustan ("Real Land of Hindus") due to North India being ruled by the Islamic Mughal rulers. The proclamation was done to enforce Hindu social code Dharmaśāstra over his reign and refer to his country as being inhabitable for Hindus. He also referred Northern India as Mughlan (Country of Mughals) and called the region infiltrated by Muslim foreigners. After the Gorkhali conquest of Kathmandu valley, King Prithvi Narayan Shah expelled the Christian Capuchin missionaries from Patan and revisioned Nepal as Asal Hindustan
