Indian emperor Ashoka, the grandson of Chandragupta Maurya, was the third king of the Maurya Dynasty. Ashoka was the ruler of India's great empire.
The Ashoka Chakra is a depiction of the Buddhist Dharmachakra - the Wheel of the Dharma.
The wheel itself depicts ideas about the cycle of Saṃsāra, which is the theory of rebirth and cyclicality of all life, matter, and furthermore the Noble Eightfold Path, which is the path of Buddhist practices leading to liberation from Saṃsāra, the painful cycle of rebirth.
The most visible use of the Ashoka Chakra today is at the centre of the National flag of India, where it is rendered in a Navyblue color on a White background.
The first 12 spokes represent 12 stages of suffering which was taught by the Buddha.
In Jainism, the Dharmachakra is worshiped as a symbol of the dharma.
India's highest military decoration awarded for courageous action or selfsacrifice away from the battlefield is also named "The Ashoka Chakra".
