Aurangazeb was one of the ablest of the Mughal kings. He assumed the title Alamgir, World Conqueror. His military campaigns in his first ten years of reign were a great success. He suppressed the minor revolts. But he faced serious difficulties in the latter part of his reign. The Jats and Satnamis and also the Sikhs revolted against AURANGAZEB him. These revolts were induced by his harsh religious policy.
The Deccan policy of the Mughals started from the reign of Akbar, who conquered Khandesh and Berar. Jahangir fought against Malik Amber of Ahmadnagar. During the Shah Jahan's reign, Aurangazeb, as governor of Deccan, followed an aggressive Deccan policy. When he became the Mughal emperor, for the first twenty five years, he concentrated on the northwest frontier. At that time, the Maratha ruler, Sivaji carved out an independent Maratha kingdom in the territories of north and south Konkan.
To contain the spread of the Marathas, Aurangazeb decided to invade Bijapur and Golkonda. He defeated Sikandar Shah of Bijapur and annexed his kingdom. Then, he proceeded against Golkonda and eliminated the Kutb Shahi dynasty. It was also annexed by him. In fact, the destruction of the Deccan kingdoms was a political blunder on the part of Aurangazeb. The barrier between the Mughals and the Marathas was removed and there ensued a direct confrontation between them. Also, his Deccan campaigns exhausted the Mughal treasury. According to J.N. Sarkar, the Deccan ulcer ruined Aurangazeb.
Aurangazeb was a staunch and orthodox Muslim in his personal life. His ideal was to transform India into an Islamic state. He created a separate department to enforce moral codes under a high-powered officer called Muhtasib. Drinking was prohibited. Cultivation and use of bhang and other drugs were banned. Aurangazeb forbade music in the Mughal court. He discontinued the practice of Jarokhadarshan. He also discontinued the celebration of Dasarah and royal astronomers and astrologers were also dismissed from service.
Initially Aurangazeb banned the construction of new Hindu temples and repair of old temples. Then he began a policy of destroying Hindu temples. The celebrated temples at Mathura and Benares were reduced to ruins. In 1679, he reimposed jiziya and pilgrim tax. He was also not tolerant of other Muslim sects. The celebration of Muharram was stopped. His invasions against the Deccan sultanates were partly due to his hatred of the Shia faith.
He was also against the Sikhs and he executed the ninth Sikh Guru Tej Bahadur. This had resulted in the transformation of Sikhs into a warring community.
His religious policy was responsible for turning the Rajputs, the Marathas and Sikhs into the enemies of Mughal empire. It had also resulted in the rebellions of the Jats of Mathura and the Satnamis of Mewar. Therefore, Aurangazeb was held responsible for the decline of the Mughal empire.
In his private life, Aurangazeb was industrious and disciplined. He was very simple in food and dress. He earned money for his personal expenses by copying Quran and selling those copies. He did not consume wine. He was learned and proficient in Arabic and Persian languages. He was a lover of books. He was devoted to his religion and conducted prayers five times a day. He strictly observed the Ramzan fasting.
In the political field, Aurangazeb committed serious mistakes. He misunderstood the true nature of the Maratha movement and antagonized them. Also, he failed to solve the Maratha problem and left an open sore. His policy towards Shia Deccan Sultanates also proved to be a wrong policy.
His religious policy was also not successful. Aurangazeb was an orthodox Sunni Muslim. But his move to apply his religious thought rigidly in a non-Muslim society was a failure. His antagonistic policies towards non-Muslims did not help him to rally the Muslims to his side. On the other hand it had strengthened political enemies of the Mughal Empire.
