On October 30, 1969, President Jomo Kenyatta banned the Kenya People’s Union. Kenya became a de facto one party state. After 1969 during Jomo's presidency, no attempt was made to form another political party even though there was no law prohibiting it.
This changed once Daniel arap Moi became the 2nd President of Kenya. A few months into his presidency, murmurs of political dissent started to gain momentum.
