Who were the indi-Europeans?

The Indo-Europeans were a group of ancient peoples who spoke languages belonging to the Indo-European language family, which includes many modern languages such as English, Spanish, Hindi, and Russian. They are believed to have originated in the Eurasian steppes, particularly around the region of the Pontic-Caspian steppe, around 4000 to 2500 BCE. Their migrations spread their languages and cultures across Europe and parts of Asia, leading to significant linguistic and cultural developments in those regions. The Indo-European hypothesis has been pivotal in understanding historical linguistics and the spread of cultures in prehistoric times.
