What is the setting of The Martyr by Ngugi wa Thiong'o?

Although it is not stated specifically in the story, it is clear to the reader familiar with Ngugi's background that it is set in Kenya during a time of rebellion among the Kikuyu people against the white plantation owners who exploit their labor. This is significant to the story because the Kikuyu were the first group of Africans in Kenya to launch an organized resistance against colonialism, beginning in the 1920s and 1930s.
