Madaraka Day

Madaraka Day is a national holiday that is celebrated every 1 June in every year in the Republic of Kenya. It commemorates the day in 1963 that Kenya attained internal self rule after being a British colony since 1920. Kenya only attained partial independence on this day in 1963 and did not become a fully established republic until about a year and a half later, on 12 December 1964. In recognition of that, Kenya also celebrates Jamhuri Day on 12 December every year.
Madaraka is a Swahili word for "authority," "the assignment of authority".
