Allahabad pillar The Allahabad pillar is an Ashoka Stambha, one of the pillars of Ashoka, an emperor of the Maurya dynasty who reigned in the 3rd century BCE. While it is one of the few extant pillars that carry his edicts,[3] it is particularly notable for containing later inscriptions attributed to the Gupta emperor, Samudragupta (4th century CE).[4] Also engraved on the stone are inscriptions by the Mughal emperor, Jahangir, from the 17th century.[2]
Ashoka Chakra The Ashoka Chakra is a depiction of the dharmachakra; represented with 24 spokes. It is so called because it appears on a number of edicts of Ashoka, most prominent among which is the Lion Capital of Ashoka. The most visible use of the Ashoka Chakra today is at the centre of the Flag of India (adopted on 22 July 1947), where it is rendered in a navy blue colour on a white background, replacing the symbol of charkha (spinning wheel) of the pre-independence versions of the flag.
