Aurangzeb was a notable expansionist and during his reign, the Mughal Empire reached its greatest extent, ruling over nearly all of the Indian subcontinent. During his lifetime, victories in the south expanded the Mughal Empire to 4 million square kilometres, and he ruled over a population estimated to be over 158 million subjects, with an annual yearly revenue of $450 million (more than ten times that of his contemporary Louis XIV of France), or £38,624,680 (2,879,469,894 rupees) in 1690. Under his reign, India surpassed China once again to become the world's largest economy, worth over $90 billion, nearly a quarter of world GDP in 1700.
