The Kurgan hypothesis is a theory that explains how the Indo-European language and culture spread across Eurasia. It suggests that there were a group of people called the Kurgans who lived on the steppes of modern-day Ukraine and Russia around 4,500 years ago. These people were skilled warriors who rode on horses and used wagons to move around.
The Kurgans believed in polytheism, which meant they worshipped multiple gods, and they had a strong patriarchal society where men were leaders. The Kurgans had a unique way of burying their dead, in mounds called kurgans, which are still visible today. This is where the theory gets its name from.
The Kurgans were said to have spread their language and way of life through a series of migrations into Europe and Asia, starting around 3000 BCE. As they moved from place to place, they mixed with other cultures and exchanged ideas, which led to the development of new languages and cultures. This is why many modern languages, such as English, German, and Hindi, share similar words and grammar structures.
In summary, the Kurgan hypothesis suggests that a group of people called the Kurgans were responsible for the spread of Indo-European languages and cultures across Eurasia. They were skilled warriors who rode on horses, believed in polytheism, and buried their dead in kurgans. As they migrated, they mixed with other cultures, which led to the development of new languages and cultures that we still see today.
