Question: In what present day country did the Xionites see victories? Passage 1:Thanjavur was successfully conquered in 1674 by Ekoji I (1675–84), the Maratha feudatory of the sultan of Bijapur and half-brother of Shivaji (1627/30-80) of the Bhonsle dynasty. Ekoji founded the Thanjavur Maratha kingdom which ruled Thanjavur till 1855. The Marathas exercised their sovereignty over Thanjavur throughout the last quarter of the 17th and the whole of the 18th century. The Maratha rulers patronized Carnatic music. In 1787, Amar Singh, the regent of Thanjavur, deposed the minor Raja, his nephew Serfoji II (1787–93) and captured the throne. Serfoji II was restored in 1799 with the assistance of the British, who induced him to relinquish the administration of the kingdom and left him in charge of Thanjavur fort and surrounding areas. The kingdom was eventually absorbed into British India in 1855 by the Doctrine of Lapse when Shivaji II (1832–55), the last Thanjavur Maratha ruler, died without a legitimate male heir. The British referred to the city as Tanjore in their records. Five years after its annexation, the British replaced Negapatam (modern-day Nagapattinam) with Thanjavur as the seat of the district administration. Under the British, Thanjavur emerged as an important regional centre. The 1871 India census recorded a population of 52,171, making Thanjavur the third largest city in the Madras Presidency. After India's independence, Thanjavur continued as the district headquarters.
 Passage 2:Rodrigo studied music under Francisco Antich in Valencia and under Paul Dukas at the École Normale de Musique in Paris. After briefly returning to Spain, he went to Paris again to study musicology, first under Maurice Emmanuel and then under André Pirro. His first published compositions date from 1923. In 1943 he received Spain's National Prize for Orchestra for Cinco piezas infantiles ("Five Children's Pieces"), based on his earlier composition of the same piece for two pianos, premiered by Ricardo Viñes. From 1947 Rodrigo was a professor of music history, holding the Manuel de Falla Chair of Music in the Faculty of Philosophy and Letters, at Complutense University of Madrid. Notable students include Yüksel Koptagel, Turkish composer and pianist.
 Passage 3:Early confrontations between the Sasanian Empire of Shapur II with the nomadic hordes from Central Asia called the "Chionites" were described by Ammianus Marcellinus: he reports that in 356 CE, Shapur II was taking his winter quarters on his eastern borders, "repelling the hostilities of the bordering tribes" of the Chionites and the Euseni ("Euseni" is usually amended to "Cuseni", meaning the Kushans), finally making a treaty of alliance with the Chionites and the Gelani, "the most warlike and indefatigable of all tribes", in 358 CE. After concluding this alliance, the Chionites (probably of the Kidarites tribe) under their King Grumbates accompanied Shapur II in the war against the Romans, especially at the Siege of Amida in 359 CE. Victories of the Xionites during their campaigns in the Eastern Caspian lands were also witnesses and described by Ammianus Marcellinus.
