### How many generations was 800 years ago?

To determine how many generations lived approximately 800 years ago, you need to consider the average length of a generation, which can vary depending on historical and cultural factors. On average, a generation is often estimated to be around 25 to 30 years. However, this can vary significantly.

If we assume an average generation length of 25 years, then 800 years ago would be roughly 32 generations ago (800 years divided by 25 years per generation). Keep in mind that this is a rough estimate, and the actual number of generations could be more or less, depending on individual family histories and cultural practices.

The length of 20 human generations can vary depending on the average age at which individuals in a particular population become parents. However, a rough estimate for a human generation is often considered to be about 25 to 30 years.

If we take the average generation length to be 25 years, then 20 human generations would be equivalent to 500 years (20 generations x 25 years per generation). Similarly, if we take the average generation length to be 30 years, then 20 generations would be equivalent to 600 years (20 generations x 30 years per generation).

Keep in mind that these estimates are rough averages, and the actual length of generations can vary among different cultures and historical periods.
