The English language was introduced to Kenya along with Great Britain's colonisation of Kenya in 1895, when the East Africa Protectorate was set up before becoming a colony in 1920. Swahili had been established as a trade language in most parts of the Swahili Coast at the time of colonization, and it was also used in education. The British reduced the influence of Swahili and made English the medium of instruction in Kenyan schools. English remained in official use after Kenya's independence on 12 December 1963. The official languages of Kenya are English and Swahili, with the latter also recognised as the national language. While English isn't used as commonly as other native languages in Kenya, it is the primarily language spoken in areas such as media, government and schools. Due to this, almost all Kenyans who have educational background know some level of English.
