In 1827 , a soldier of the , British east India company, James Lewis , was fed up with the antics of the company, and so decided to desert the army, to stay undercover, he changed his name, and set out to follow his passion, travelling, after travelling for 2 years in Indian subcontinent, he reached the Punjab region in 1829 , here he come across the ancient ruins of an unknown ancient city, he has no idea , how old this ruins are, but he was passionate about history, he started documenting , whatever he comes across, he makes notes , drawings , James Lewis was unaware , that he actually, discovered the ancient city of harappa,

After this incident, 100 years later , in 1920 , world get some more information , about this ancient civilisation, jhon marshal was appointed as the chief of ASI and it was found that the ruins were 5000 years old , meanwhile, another historical site was founded, on the banks of Indus River, they found several human skeleton, and this place was named mohanjo -daro , the civilisation was named Indus Valley civilisation today in 2023 , we know many things about this civilisation, but two things are still mysterious, first , the harappan language, and second how this great civilisation came to an end

Problem was that as for Egyptian language we found a stone called rosata stone , to learn it , we don’t find any type of rosata stone , so we can compare this language, to other languages, we have no base stone like other ancient languages, to compare, in English language, we have patterns to find the language, and alphabets , similarly in indus language we have some symbols to follow, actually, it could not be translated because the texts are too short , we have no bilingual inscription, we don’t know which language or languages were transcribed 2) many scholars believe that , the collapse of Indus Valley civilisation happened due to climate change, while others conclude , that a great flood struck the area , some believed that a nomodic indo-European tribe called Aryan invaded the area , but what is the real reason it is mysterious, all have different opinions about end of Indus Valley civilisation
