Nigeria, as well as through trade with Europeans, mostly in pepper and ivory. In the early 16th century, the Ọba sent an ambassador to Lisbon, and the King of Portugal sent Christian missionaries to Benin. Some residents of Benin could still speak a pidgin Portuguese in the late 19th century. Many Portuguese loan words can still be found today in the languages of the area. A Portuguese captain described the city in 1691:"Great Benin, where the king resides, is larger than Lisbon; all the streets run straight and as far as the eye can see. The houses are large, especially that of the king, which is richly decorated and has fine columns. The city is wealthy and industrious. It is so well governed that theft is unknown and the people live in such security that they have no doors to their houses". This was at a time when theft and murder were rife in London. On 17 February 1897, Benin City fell to the British. In the "Punitive Expedition", a 1,200-strong British force, under the command of Admiral Sir Harry Rawson, captured, sacked, and burnt the city after all but two men from a previous British delegation led by Acting Consul General Philips were ambushed and killed. Alan Boisragon, one of the survivors of the Benin Massacre, included references of the practice of human sacrifice in the city in a firsthand account written in 1898 (one year after the Punitive Expedition). James D. Graham notes that although "there is little doubt that human sacrifices were an integral part of the Benin state religion from very early days," firsthand accounts regarding such acts often varied significantly, with some reporting them and others making no mention of them. The "Benin Bronzes", portrait figures, busts and groups created in iron, carved ivory, and especially in brass (conventionally called "bronze"), were looted from the Benin City palace by the expeditionary force and are currently on display in various museums around the world. Some of the bronzes were auctioned off to compensate for the expenses incurred during the capture and occupation of the city. Most of these artifacts can be found today in Western museums and locations around the world. In recent years, various appeals have gone to various museums and governments to return such artifacts. The most prominent of these artifacts was the famous Queen Idia mask used as a mascot during the Second
