The oldest inscription of Haryana is the Topra inscription. It is a Brahmi inscription found on a stone slab at Topra Kalan, about 15 km from Kurukshetra in Haryana, India. The inscription is dated to the 3rd century BCE and records the gift of a village by a king named AÅoka to the Buddhist Sangha.
The Topra inscription is significant because it is the earliest evidence of the presence of Buddhism in Haryana. It also provides important information about the political and social conditions of the region in the 3rd century BCE.
The other options are incorrect because they are not the oldest inscriptions of Haryana. The Ropar inscription is dated to the 2nd century BCE, the Pehowa inscription is dated to the 1st century BCE, and the Banawali inscription is dated to the 2nd millennium BCE.
The Topra inscription is a valuable source of information about the history of Haryana. It is a reminder of the region’s rich cultural heritage and its long association with Buddhism.
