A handful of Bronze Age relics has fostered an assumption that prehistoric settlers inhabited Ibiza thousands of years ago. Greater evidence of such a people is found on Mallorca and Menorca than on Ibiza, but one of the Balearics' most important sites is actually on the island of Formentera, where the megalithic monument/tomb of Ca Na Costa has been dated to 2000 b.c. Ibiza's key location between Africa and ancient Iberia made it a convenient stopover for Mediterranean seafarers, such as the Phoenician traders, who called the island Ibosim. The Greeks dubbed it Ebysos, the Romans called it Ebusus, and the Moors, Yebisah. The Carthaginians: A detailed history of the island doesn't begin until it became a colony of Carthage in the 7th century b.c. . The Carthaginians originally came from the area comprising present-day Lebanon, and from their bases in North Africa and what's now Spain, they challenged the Roman Empire for domination of the Mediterranean region. Their interest in Ibiza lay partly in its vast salt flats, which to this day remain the source of a profitable industry. They capitalized on the natural resources by using the salt to cure fish, which they exported to their home country. The Carthaginians also carried out lead mining and continued to be of significance up until this century. It is believed that the lead pellets which were used by the Carthaginian general Hannibal were made on Ibiza. The Carthaginians also considered the island a holy place, and here in great splendour they buried thousands of their citizens in a huge necropolis on the Puig des Molins (Hill of the Windmills) below the Dalt Vila (Old Town) of Ibiza. Under the gnarled olive trees archaeologists have uncovered a treasure trove of statues, jewellery, pitchers, tools, and coins, which are now displayed in the town's two archaeological museums. The Romans never really infiltrated Ibiza, and even after the defeat of Hannibal in 202 b.c. during the Second Punic War their influence was restrained. Only with the fall of Carthage in 146 b.c. did they manage to make inroads, but, as local historians stress, Ibiza was neither conquered nor annexed by Rome, but confederated, retaining remarkable autonomy. For centuries to come the old Carthaginian traditions were allowed to continue on Ibiza alongside the new Roman way of life. <sep>What did Carthaginians capitalize on in Ibiza?<sep>Salt to cure fish

Alexander II (Russian: Aleksandr II Nikolaevich, tr. Aleksandr II Nikolaevich; IPA: [aljI'ksandr fta'roj njIka'lajIvjItc]; 29 April [O.S. 17 April] 1818 in Moscow - 13 March [O.S. 1 March] 1881 in Saint Petersburg) was the Emperor of Russia from 2 March 1855 until his assassination in 1881. He was also the King of Poland and the Grand Duke of Finland. Alexander was the most successful Russian reformer since Peter the Great. His most important achievement was the emancipation of serfs in 1861, for which he became known as Alexander the Liberator (Russian: Aleksandr Osvoboditel', tr. Aleksandr Osvoboditel; IPA: [aljI'ksandr asv@ba'djitjIlj]). The tsar was responsible for numerous other reforms including reorganizing the judicial system, setting up elected local judges, abolishing capital punishment, promoting local self-government through the zemstvo system, imposing universal military service, ending some of the privileges of the nobility, and promoting the universities. Despite these reforms, during his reign, his brutal secret police, known as the Third Section, sent thousands of dissidents into exile in Siberia. In foreign policy, Alexander sold Alaska to the United States in 1867, fearing the remote colony would fall into British hands if there was another war. He sought peace, moved away from bellicose France when Napoleon III fell in 1871, and in 1872 joined with Germany and Austria in the League of the Three Emperors that stabilized the European situation. Despite his otherwise pacifistic foreign policy, he fought a brief war with Turkey in 1877-78, pursued further expansion into Siberia and the Caucasus, and conquered Turkestan. Although disappointed by the results of the Congress of Berlin in 1878, Alexander abided by that agreement. Among his greatest domestic challenges was an uprising in Poland in 1863, to which he responded by stripping that land of its separate Constitution and incorporating it directly into Russia. Alexander was proposing additional parliamentary reforms to counter the rise of nascent revolutionary and anarchistic movements when he was assassinated in 1881. <sep>Why is Alexander II called Aleksandr Osvoboditel?<sep>Because he captured Poland

As for the Italians, we know that Paesiello, who was a famous intriguer against his musical rivals, was a devoted husband whose wife was an invalid and who died soon after her death. Cherubini married Mademoiselle Cecile Turette, when he was thirty-five, and the marriage was not a success. He left a son and two daughters. Spontini, one of whose best operas was based on the life of that much mis-married enthusiast for divorce, John Milton, took to wife a member of the Erard family. In the outer world Spontini was famous for his despotism, his jealousy, his bad temper, and his excessive vanity. None of these qualities as a rule add much to home comfort, and yet, it is said that he lived happily with his wife. We may feel sure that some of the bad light thrown on his character is due purely to the jealousy of rivals, when we consider his domestic content, his ardent interest in the welfare of Mozart's widow and children, and the great efforts he made to secure subscriptions for the widow's biography of Mozart. <sep>Who were three Italians, whom this passage describes?<sep>Cherubini
