字幕依据：20th century, the British were justifying their 200 year old kingdom in India by giving it the name of Tolerant Imperialism. They claimed that they have made India cultured and have done a favor on it. But they did not know that this land of India had lived its golden era thousands of years ago. 32XmLQxwhlQ@0:00
字幕依据：Its water management and drainage system were so magnificent that even today there are no such facilities in many cities in the world. After decades of excavation, the script of that time was also found from here, but the surprising thing is that the language of ancient civilizations such as Mesopotamian and Egyptian has been read. 32XmLQxwhlQ@1:11
字幕依据：To go to Lahore, he had reached the Punjab province, where he saw a lot of ruins and various remains in them, which proved to be very ancient. He was unaware of the fact that he had unexpectedly discovered an ancient city of thousands of years old civilization. 32XmLQxwhlQ@2:19
字幕依据：The carbon dating technology had come to India, which was believed to be thousands of years old in the survey. Thus, for the first time, a city was confirmed to be discovered here, which began to talk about this civilization that was being discovered in India all over the world. 32XmLQxwhlQ@4:41
字幕依据：That's why it was called the Indus Valley Civilization. The first discovery was made by Harappa, so it is also known as the Harappan civilization. The existence of this civilization had surprised the whole world. Until then, Mesopotamian civilization, Egyptian civilization and Chinese civilization were the world's largest civilizations. 32XmLQxwhlQ@5:51
字幕依据：South Asia is one of the most vibrant cultural areas on planet Earth. A cradle of civilization, it has long been a place where great nations rise, thrive and fall. The mighty Mughals, opulent Mauryas and sophisticated Guptas are just some examples of Empires that have left their mark in the subcontinent. 7GRob-zFs0k@0:06
字幕依据：thousand years as trade and irrigation increased the size of towns into large cities which co-existed with nomadic and vullage populations. By the 5,000s BCE, large cultural regions with their own styles of pottery had emerged in northwest South Asia, which would form the nuclei of the major cities the culture was known for. 7GRob-zFs0k@3:21
字幕依据：symphony of cultural blossoming, mercantile magnificence, and artistic eloquence. Indus Cities: Having given a short overview of the little we know of the Indus Valley’s long history, let us now take a step out from the flow of time and paint a picture of what life looked like in this ancient civilization, both in the rural villages and the larger cities. 7GRob-zFs0k@7:03
