This is a map of Gupta empire of about 475 AD ruling on vast geographical area of India, if u see India’s definition is there, upto large extent although there are some kingdoms in between. Look at the map of Europe in 475 AD. Look at western Europe. You will be unable to recognize most of the countries. Even England is not present in 475 AD. Only tribes are residing in different groups. Look in 1 AD. Satvahanas and Kalingas’ kingdoms are being seen. If u look at Europe in 1 AD, this is Roman Empire which does not correlate with any European country of today. It is true that bharat’s kingdoms were changing time to time but somehow kingdom’s boundary correlate with today. But roman’s empire doesn’t correlate with any of today’s European country.
Let’s move forward. In 400 AD some of these kingdoms emerged. Persia can be seen which has different story and this one is Roman Empire. This one is 1000 AD. Here some of regions can be seen which can be correlated to today’s countries but these too are very different like here it is Portugal today but this is something very different kingdom. Greece which is called ancient civilization has no indication here. England is also there but of limited land, several tribes are fighting. Germany is not there. Holy Roman Empire kingdom is there on present Germany. If u look at Spain, some terrain is here while some is above. So it means it’s very different from today’s situation. So, they said that India was not a nation. Then were u a nation? When did u become nation? What is your basis?
So even in 1000 AD you cannot say there was something like today. In 1500 AD something grew, what is difference now? Ottoman Empire has replaced Roman Empire. So this Eastern Europe and Greece is under ottoman now. This is Muslim empire. Here Egypt can be seen which will be discussed separately. If you look at Germany there are many principalities, warlords, kingdoms, tribes are ruling there. France’s boundary is also different from today, England too. This is whole story of 1500 AD.
