The city went through serious troubles in the mid-fourteenth century. On the one hand were the decimation of the population by the Black Death of 1348 and subsequent years of epidemics and on the other, the series of wars and riots that followed. Among these were the War of the Union, a citizen revolt against the excesses of the monarchy, led by Valencia as the capital of the kingdom and the war with Castile, which forced the hurried raising of a new wall to resist Castilian attacks in 1363 and 1364. In these years the coexistence of the three communities that occupied the cityChristian, Jewish and Muslim was quite contentious. The Jews who occupied the area around the waterfront had progressed economically and socially, and their quarter gradually expanded its boundaries at the expense of neighbouring parishes. Meanwhile, Muslims who remained in the city after the conquest were entrenched in a Moorish neighbourhood next to the present-day market Mosen Sorel. In 1391 an uncontrolled mob attacked the Jewish quarter, causing its virtual disappearance and leading to the forced conversion of its surviving members to Christianity. The Muslim quarter was attacked during a similar tumult among the populace in 1456, but the consequences were minor.
When was the Muslim section attacked?
****
The answer: 1456

The creation of a modern industrial economy took place. With the creation of a transportation and communication infrastructure, the corporation became the dominant form of business organization and a managerial revolution transformed business operations. In 1890, Congress passed the Sherman Antitrust Actthe source of all American anti-monopoly laws. The law forbade every contract, scheme, deal, or conspiracy to restrain trade, though the phrase "restraint of trade" remained subjective. By the beginning of the 20th century, per capita income and industrial production in the United States exceeded that of any other country except Britain. Long hours and hazardous working conditions led many workers to attempt to form labor unions despite strong opposition from industrialists and the courts. But the courts did protect the marketplace, declaring the Standard Oil group to be an "unreasonable" monopoly under the Sherman Antitrust Act in 1911. It ordered Standard to break up into 34 independent companies with different boards of directors.
What creations brought in the modern industrial economy?
****
The answer: transportation and communication infrastructure
