When did Kenya become known as Kenya?

"As part of East Africa, Kenya has seen human habitation since the Lower Paleolithic period. The Bantu expansion reached the area by the first millennium AD, and the borders of the modern state comprise the crossroads of the Niger-Congo, Nilo-Saharan, and Afro-Asiatic linguistic areas of Africa, making Kenya a truly multi-cultural state. European and Arab presence in Mombasa dates to the Early Modern period, but European exploration of the interior began only in the 19th century. The British Empire established the East Africa Protectorate in 1895, known from 1920 as the Kenya Colony. The independent Republic of Kenya was founded in December 1963."
