During the five months that Menasseh was preparing for his journey, Cromwell was not idle. Colonial questions were occupying his mind very largely, and on these questions he was in the habit of receiving advice from one at least of the London Marranos, Simon de Caceres, a relative of Spinoza, and an eminent merchant who had large interests in the West Indies, and had enjoyed the special favour of the King of Denmark and the Queen of Sweden.[64] It was no doubt at the instigation of De Caceres that in April 1655 Cromwell sent a Jewish physician, Abraham de Mercado, with his son Raphael to Barbados.[65] Later in the year he was deep in consultation with De Caceres in regard to the defences of the newly acquired island of Jamaica, and a plan for the conquest of Chili.[66] The most important result of these confabulations was a scheme for colonising Surinam (which since 1650 had been a British colony) with the Jewish fugitives from Brazil, who had been obliged to leave Pernambuco and Recife through the Portuguese reoccupation of those towns. The idea was, no doubt, suggested by Dormido, himself one of the victims of the Portuguese conquest. In order to attract the Jews, they were granted a charter in which full liberty of conscience was secured to them, together with civil rights, a large measure of communal autonomy, and important land grants.[67] Thus a beginning was made in the solution of the Jewish question by their admission as citizens to one of the colonial dependencies of Great Britain. This was the first important step achieved by Cromwell, and it illustrates at once his deep interest in the Jewish question, and the practical considerations which actuated him in seeking its solution. IV. THE APPEAL TO THE NATION On his arrival in London, Menasseh, with his retinue of three Rabbis,[68] was lodged with much ceremony in one of the houses opposite the New Exchange, in the then fashionable Strand, the Piccadilly of its day. These houses were frequented by distinguished strangers who desired to be near the centre of official life at Whitehall, and the fact that Menasseh with his slender purse took up his abode in one of them, instead of seeking hospitality with his brother-in-law or his Marrano co-religionists in the city, shows at once the importance with which his mission was invested.[69] He was the guest of the Protector, bidden to London to discuss high affairs of state, and as such it was obviously inadmissible that he should be hidden away in some obscure address in an East-End Alsatia.
