It is said that Phoenician traders reached there as early as the eleventh century before the Christian era. In 238 B. C., or three years after the close of the first Punic war, Hamilcar Barca, the famous Carthaginian general, crossed from Africa into Spain, taking with him his son-in-law, Hasdrubal, and his son Hannibal, both of whom were destined to play great parts in the coming struggle between Carthage and Rome. From a few trading posts, Hamilcar extended the Carthaginian dominion in Spain to that of a great province, that not only proved a source of immense revenue, but that also furnished a never-failing supply of warlike troops for the armies of Carthage. The second Punic war ended the sway of the Carthaginians in Spain, and from 201 B. C. until 406 A. D. the country was under Roman rule. Then came the barbarian invasion and the Visigothic kings, whose power was shattered in turn when the Berber Tarik defeated King Roderic in 711. For centuries afterward the struggle of reconquest went on until Granada, the only remaining Mohammedan stronghold, surrendered to Ferdinand and Isabella on January 2, 1492. That same year, under the auspices of these sovereigns, Columbus set out on his first journey westward, and with his discovery of America came a revolution in the sugar industry of the world. Spain is the only cane-sugar-producing country in Europe. Sugar cane was brought there by the Arabs when they conquered Granada, and its cultivation had assumed important proportions in that kingdom at the time of the expulsion of the Moors. The introduction of the plant in America had a serious effect upon sugar production in Spain and other countries of the Old world, and over three hundred years later the Spanish growers of cane had to meet the competition of the beet sugar of central Europe. Finally the loss of her colonies in 1898 stimulated the industry in the mother country by relieving the Spanish planter from protected competition in his home market. In 1903 Spain had fifty beet-sugar factories, thirty-two cane-sugar mills, fifteen syrup mills, eleven refineries and two factories that turned out sorghum sugar and glucose. Shortly afterward, however, prices in Spain dropped below the cost of production, so that a period of profit was followed by a period of heavy loss. As a result of this state of affairs, the Sociedad General Azucarera de España was formed. This organization comprised forty-three beet factories, thirteen cane factories and thirteen other mills, and its object was to limit the number of mills in operation and to introduce greater efficiency into cultivation methods. The plan did not prove successful, and finally, after lengthy discussions between the Sociedad General, the independent producers and the government, it was decided to fix the excise tax on sugar at thirty-five pesetas per 220.4 pounds, and it was agreed that no new factory should be built within a fifty-mile radius of any factory in operation.
