Muhi-ud-Din Muhammad also known as Aurangzeb or by his title Alamgir was the sixth emperor of the Mughal Empire. He ruled over most of the Indian subcontinent through Islamic Sharia. His reign lasted for 49 years from 1658 until his death in 1707. During this time, Aurangzeb greatly expanded the territory of the Mughal Empire. He was constantly at war. Victories in the south expanded the Empire to more than 4 million square kilometres as he was the only ruler after Emperor Ashoka to ruled over such a largest land as a result unifying the entirety of Indian Subcontinent (South Asia) under one ruler after two millennium. His empire was the world's largest economy, valued 27% of world's GDP. He was the last great and powerful ruler of the Mughal dynasty. After his death, the power of the Mughal Empire declined quickly due to weak and ineffective successors. His administration of Mughal empire led to its apex in terms of territory and wealth. He defeated the British in their fruitless attempt to colonize India as matter of fact after the humiliating defeat of Brits (EIC), they had to prostrate on mat before the emperor and begged for forgiveness but were forgiven later after paying a large sum in compensation and promise never to dare such insolence. Emperor Aurangzeb's exchequer raised a record £100 million in annual revenue through various sources like taxes, customs and land revenue, "et al." from 24 provinces. He had an annual yearly revenue of $450 million, more than ten times that of his contemporary {Louis XIV of France}.
