The central highlands were already home to over a million members of the Kikuyu people, most of whom had no land claims in European terms and lived as itinerant farmers. To protect their interests, the settlers banned the growing of coffee, introduced a hut tax, and the landless were granted less and less land in exchange for their labour. A massive exodus to the cities ensued as their ability to provide a living from the land dwindled. There were 80,000 white settlers living in Kenya in the 1950s.
