What is the last place listed that engaged in the slave trade?, Context: The slave trade was engaged in by European state and non-state actors such as Great Britain, the Netherlands, Portugal and private companies, as well as various African states and non-state actors. With rising anti-slavery sentiment at home and changing economic realities, Great Britain outlawed the international slave trade in 1807. Following the Napoleonic Wars, Great Britain established the West Africa Squadron in an attempt to halt the international traffic in slaves. It stopped ships of other nations that were leaving the African coast with slaves; the seized slaves were taken to Freetown, a colony in West Africa originally established for the resettlement of freed slaves from Britain. Britain intervened in the Lagos Kingship power struggle by bombarding Lagos in 1851, deposing the slave trade friendly Oba Kosoko, helping to install the amenable Oba Akitoye, and signing the Treaty between Great Britain and Lagos on 1 January 1852. Britain annexed Lagos as a Crown Colony in August 1861 with the Lagos Treaty of Cession. British missionaries expanded their operations and travelled further inland. In 1864, Samuel Ajayi Crowther became the first African bishop of the Anglican Church.

what were Richard of Devizes, William of Newburgh, Roger of Hoveden and Ralph de Diceto?, Context: Historical interpretations of John have been subject to considerable change over the years. Medieval chroniclers provided the first contemporary, or near contemporary, histories of John's reign. One group of chroniclers wrote early in John's life, or around the time of his accession, including Richard of Devizes, William of Newburgh, Roger of Hoveden and Ralph de Diceto. These historians were generally unsympathetic to John's behaviour under Richard's rule, but slightly more positive towards the very earliest years of John's reign. Reliable accounts of the middle and later parts of John's reign are more limited, with Gervase of Canterbury and Ralph of Coggeshall writing the main accounts; neither of them were positive about John's performance as king. Much of John's later, negative reputation was established by two chroniclers writing after the king's death, Roger of Wendover and Matthew Paris, the latter claiming that John attempted conversion to Islam in exchange for military aid from the Almohad ruler Muhammad al-Nasir - a story which is considered to be untrue by modern historians.
