Indo-European migrations

Indo-european migrations were a time in history when a lot of people moved around the world. They were like a big group of people who travelled from one place to another to settle in different countries. Over time, these people took their culture, language and ideas with them and spread them across the world. This is why there are so many languages, cultures and ideas that are similar in different places around the world today.
