By the 1930s, approximately 30,000 white settlers lived in Agikuyu country and gained a political voice because of their contribution to the market economy. The area was already home to over a million members of the Kikuyu nation, most of whom had been pushed off their land by the encroaching European settlers, and lived as itinerant farmers. To protect their interests, the settlers banned the production of coffee, introduced a hut tax, and landless workers 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.
