The map below shows us the migratory patterns of the Indo-Europeans, and with their migrations, the spread of the their language as well. As the Indo-Europeans started to migrate from their homeland in the lowlands between the Black and Caspian seas, they were spreading their culture with them. This led to their language seemingly distant regions that do not seem connected. As they were moving in different areas, Europe, India, Iran, Central Asia, their language started to change, so lot of new dialects emerged, and later those dialects gave birth to new languages, though all of those languages kept their basis and remained part of the same linguistic family.
