Still even in Rhode Island it was only tolerance; the recognition of equal rights was yet to come with the Declaration of Independence. In reply to a petition of the Jews, the General Assembly of Rhode Island, in 1684, affirmed the right of the Jews to settle in the colony, declaring that “they may expect as good protection here as any stranger being not of our nation residing among us in His Majesty’s colony ought to have, being obedient to His Majesty’s laws.” More Jewish settlers arrived from the West Indies in 1694; but the great impulse to the commercial activity which raised Newport to the zenith of its prosperity was given by a number of Portuguese Jews who settled there about the middle of the eighteenth century. Most prominent among those were Jacob Rodrigues Rivera (died at an advanced age in 1789), who arrived in 1745, and Aaron Lopez, who came in 1750. The former introduced into America the manufacture of sperm oil, having brought the art with him from Portugal, and it soon became one of the leading industries; Newport, whose inhabitants were engaged in whale fishing, had seventeen manufactories of oil and candles and enjoyed a practical monopoly of this trade down to the Revolution. Aaron Lopez (died May 28, 1782), who was Rivera’s son-in-law, became the great merchant prince of New England. (Ezra Stiles says of him, that for honor and extent of commerce he was probably surpassed by no merchant in America.) The advantages of this important seaport were quickly comprehended by this sagacious merchant, and to him in a larger degree than to any one else was due the rapid commercial development that followed. He was the means of inducing more than forty Jewish families to settle there, the heads of many of which were men of wealth, mercantile sagacity, high intelligence and enterprise. In fourteen years after Lopez settled there, Newport had 150 vessels engaged in trade with the West Indies alone, besides an extensive trade which was carried on as far as Africa and the Falkland Islands. The Jews were even then, nearly three hundred years after the expulsion, transferring to the liberal English colonies the wealth and the still more valuable business ability and commercial connections which they could not freely or safely employ as Marranos in Portugal. The emigration of secret Jews from that country increased after the great earthquake at Lisbon (1755), and a considerable portion went to Rhode Island. One of the vessels from that unhappy city, bound for Virginia, was driven into Narragansett Bay, and its Jewish passengers remained at Newport.
