The Slavery Abolition Act 1833 (citation 3 & 4 Will. IV c. 73) was an 1833 Act of the Parliament of the United Kingdom abolishing slavery throughout the British Empire (with the exceptions "of the Territories in the Possession of the East India Company," the "Island of Ceylon," and "the Island of Saint Helena", which exceptions were eliminated in 1843). The Act was repealed in 1998 as part of a wider rationalisation of English statute law, but later anti-slavery legislation remains in force.
The Slavery Abolition Act 1833 was repealed in its entirety under the Statute Law (Repeals) Act 1998. However, this repeal has not made slavery legal again, as sections of the Slave Trade Act 1824, Slave Trade Act 1843 and Slave Trade Act 1873 are still in force. In addition the Human Rights Act 1998 incorporates into British Law Article 4 of the European Convention on Human Rights which prohibits the holding of persons as slaves
