History of the Jews in Madeira History of the Jews in Madeira History of the Jews in Madeira spans the entire length of the history of Madeira itself, from Crypto-Jews to World War II evacuees. Like the Jews of mainland Portugal, Madeira jews are mainly related to Sephardi history, a Jewish ethnic division that represents communities who have originated in the Iberian Peninsula. There was once a Synagogue of Funchal, which is now disused. Menasseh Ben Israel was born in Madeira in 1604. Jews from Morocco arrived in 1819 and set themselves up in the cloth and wine trades. The Abudarham family from Gibraltar were involved
Madeira over 6,000 "arrobas" (an "arroba" was equal to 11 to 12 kilograms) by 1455, using advisers from Sicily and financed by Genoese capital. (Genoa acted as an integral part of the island economy until the 17th century.) The accessibility of Madeira attracted Genoese and Flemish traders, who were keen to bypass Venetian monopolies. Sugarcane production was the primary engine of the island's economy, increasing the demand for labour. African slaves were used during portions of the island's history to cultivate sugar cane, and the proportion of imported slaves reached 10% of the total population of Madeira by the 16th century.
