Input: Consider Input: Passage: Most historians describe the contacts between the Mongol Empire and the Western Europeans as a series of attempts, missed opportunities, and failed negotiations. Christopher Atwood, in the 2004 Encyclopedia of Mongolia and the Mongol Empire, summed up the relations between Western Europe and the Mongols: "Despite numerous envoys and the obvious logic of an alliance against mutual enemies, the papacy and the Crusaders never achieved the often-proposed alliance against Islam."A few other historians argue there was an actual alliance, but do not agree on the details: Jean Richard wrote that an alliance began around 1263. Reuven Amitai stated that the closest thing to actual Mongol-Frankish military coordination was when Prince Edward of England attempted to coordinate activities with Abaga in 1271. Amitai also mentioned the other attempts towards cooperation, but said, "In none of these episodes, however, can we speak of Mongols and troops from the Frankish West being on the Syrian mainland at the same time." Timothy May described the alliance as having its peak at the Council of Lyon in 1274, but that it began to unravel in 1275 with the death of Bohemond, and May too admitted that the forces never engaged in joint operations. Alain Demurger, in his own book The Last Templar, said that an alliance was not sealed until 1300.There also continues to be debate about whether or not an alliance would have been a wise idea, and whether the Crusaders at that point in history were even relevant to the Persian-Mongol conflict. The 20th-century historian Glenn Burger said, "The refusal of the Latin Christian states in the area to follow Hethum's example and adapt to changing conditions by allying themselves with the new Mongol empire must stand as one of the saddest of the many failures of Outremer." This was similar to the view of Steven Runciman, who argued, "Had the Mongol alliance been achieved and honestly implemented by the West, the existence of Outremer would almost certainly have been prolonged. The Mameluks would have been crippled if not destroyed; and the Ilkhanate of Persia would have survived as a power friendly to the Christians and the West". However, David Nicolle, describing the Mongols as "potential allies", said that early historians were writing from the benefit of hindsight, and that overall the major players were the Mamluks and the Mongols, with Christians just "pawns in a greater game.".
Question: Who did Jean Richard claim had an alliance around 1263?

Output: Mongol Empire.

Input: Consider Input: Passage: Tchaikovsky remained abroad for a year after the disintegration of his marriage. During this time, he completed Eugene Onegin, orchestrated his Fourth Symphony, and composed the Violin Concerto. He returned briefly to the Moscow Conservatory in the autumn of 1879. For the next few years, assured of a regular income from von Meck, he traveled incessantly throughout Europe and rural Russia, mainly alone, and avoided social contact whenever possible. During this time, Tchaikovsky's foreign reputation grew and a positive reassessment of his music also took place in Russia, thanks in part to Russian novelist Fyodor Dostoyevsky's call for "universal unity" with the West at the unveiling of the Pushkin Monument in Moscow in 1880. Before Dostoyevsky's speech, Tchaikovsky's music had been considered "overly dependent on the West". As Dostoyevsky's message spread throughout Russia, this stigma toward Tchaikovsky's music evaporated. An unprecedented acclaim for him even drew a cult following among the young intelligentsia of Saint Petersburg, including Alexandre Benois, Leon Bakst and Sergei Diaghilev.Two musical works from this period stand out. With the Cathedral of Christ the Saviour nearing completion in Moscow in 1880, the 25th anniversary of the coronation of Alexander II in 1881, and the 1882 Moscow Arts and Industry Exhibition in the planning stage, Nikolai Rubinstein suggested that Tchaikovsky compose a grand commemorative piece. Tchaikovsky agreed and finished it within six weeks. He wrote to Nadezhda von Meck that this piece, the 1812 Overture, would be "very loud and noisy, but I wrote it with no warm feeling of love, and therefore there will probably be no artistic merits in it". He also warned conductor Eduard Napravnik that "I shan't be at all surprised and offended if you find that it is in a style unsuitable for symphony concerts". Nevertheless, the overture became, for many, "the piece by Tchaikovsky they know best"., particularly well-known for the use of cannon in the scores.On 23 March 1881, Nikolai Rubinstein died in Paris. That December, Tchaikovsky started work on his Piano Trio in A minor, "dedicated to the memory of a great artist". First performed privately at the Moscow Conservatory on the first anniversary of Rubinstein's death, the piece became extremely popular during the composer's lifetime; in November 1893, it would become Tchaikovsky's own elegy at memorial concerts in Moscow and St. Petersburg.
Question: What is the first name of the person who assured Tchaikovsky a regular income which he used to travel incessantly throughout Europe and rural Russia?

Output: Nadezhda.

Input: Consider Input: Passage: In 1848, at the age of thirteen, Saint-Saens was admitted to the Paris Conservatoire, France's foremost music academy. The director, Daniel Auber, had succeeded Luigi Cherubini in 1842, and brought a more relaxed regime than that of his martinet predecessor, though the curriculum remained conservative. Students, even outstanding pianists like Saint-Saens, were encouraged to specialise in organ studies, because a career as a church organist was seen to offer more opportunities than that of a solo pianist. His organ professor was Francois Benoist, whom Saint-Saens considered a mediocre organist but a first-rate teacher; his pupils included Adolphe Adam, Cesar Franck, Charles Alkan, Louis Lefebure-Wely and Georges Bizet. In 1851 Saint-Saens won the Conservatoire's top prize for organists, and in the same year he began formal composition studies. His professor was a protege of Cherubini, Fromental Halevy, whose pupils included Charles Gounod and Bizet.Saint-Saens's student compositions included a symphony in A major (1850) and a choral piece, Les Djinns (1850), after an eponymous poem by Victor Hugo. He competed for France's premier musical award, the Prix de Rome, in 1852 but was unsuccessful. Auber believed that the prize should have gone to Saint-Saens, considering him to have more promise than the winner, Leonce Cohen, who made little mark during the rest of his career. In the same year Saint-Saens had greater success in a competition organised by the Societe Sainte-Cecile, Paris, with his Ode a Sainte-Cecile, for which the judges unanimously voted him the first prize. The first piece the composer acknowledged as a mature work and gave an opus number was Trois Morceaux for harmonium (1852).
Question: What is the name of the person whose professor was a protege of Cherubini?
Output: Saint-Saens.
