The Colony and Protectorate of Sierra Leone (informally British Sierra Leone) was the British colonial administration in Sierra Leone from 1808 to 1961, part of the British Empire from the abolitionism era until the decolonisation era. The Crown colony, which included the area surrounding Freetown, was established in 1808. The protectorate was established in 1896 and included the interior of what is today known as Sierra Leone.
