Approximately 4,500 years prior to the modern era definitely called great Indus valley civilization existed on the indian subcontinent. That civilization not only contributed to the development of its own sophisticated urban infrastructure, social order, and rich culture, but also paved the way for the evolution of civilised societies across the globe. This civilization spanned the region encompassing present-day India, Pakistan and Afghanistan; when compared to its contemporaries, it was remarkably advanced for its time. It is considered truly unique because—despite operating with limited resources (specifically, it is believed that they have made minimal use of iron)—it remained far ahead of its era. Serving as a beacon of excellence, this civilization propelled its work culture forward and demonstrated exceptional standards across Administrative, Political, Cultural, and religious spheres. What is needed today is to intensify the exploration of this magnificent civilization so that its legacy and influence may reach and inspire a wider audience.
