The county is the pre-historic manhood home ever since a million years ago. For about 3500 years ago, there was a village with temporally homes and about one thousand population. This village was located about 5kms away from the current Nakuru town. In the days of colonial, white settlers were attracted to this area and began their agricultural activities.
