Who were the relligos people in the indus valley and what did they do?

The Relligos people in the Indus Valley are not a recognized group in historical or archaeological records. It's possible that there may be confusion with another term or group. The Indus Valley Civilization, which thrived around 2500-1900 BCE, was known for its advanced urban planning, trade, and social organization, but specific groups like the "Relligos" do not appear in the established literature. If you meant another group or concept, please clarify for a more accurate response.
