The empire known for its military conquests and use of elephants in battle is the Maurya Empire, which existed in ancient India. Founded by Chandragupta Maurya in the 4th century BCE, the empire expanded significantly under the rule of his grandson, Ashoka the Great. Elephants played a crucial role in Mauryan warfare, serving as formidable forces in battles. Ashoka's later reign marked a transition towards non-violence and the promotion of Buddhism, greatly influencing Indian culture and society. The Maurya Empire is notable not only for its military prowess but also for its contributions to administration, architecture, and the spread of ethical governance.
