Input: Consider Input: Question: How old was Evrenos Beg when he first fought Pedro's forces at Leontari? Passage:On 6 September that year, Pope Urban VI declared that as James of Baux's successors had forfeited their rights to the Holy See, the principality belonged to him and he devolved its government on Paul Foscari, the archbishop of Patras, who in turn made Pedro vicar general. Pedro was constantly at war with the Despotate of Morea, against whom he even used Ottoman pirates, and the Duchy of Athens under Nerio I Acciaioli. The latter was captured near Vostitsa on 10 September 1389 while trying to sit to talks with Pedro concerning Argos and Nauplia. He had to buy his freedom with concessions to the Navarrese ally, Venice. Late in 1394 or early in 1395, the Turkish general Evrenos Beg invaded the despotate and met Pedro's forces at Leontari. Together the two besieged and took Akova (28 February). After Evrenos returned to Thessaly, Pedro was defeated by the Greeks and taken captive with the grand constable Andronico Asano Zaccaria, his brother-in-law. In December, Venice paid 50,000 hyperpers for the release of her allies.

Input: Consider Input: Question: How long had the Algerian war been going on when Kopanski was 14? Passage:In 1962, when only 14, he was fascinated by the success of the Arab national and anti-colonial forces that defeated the French colonial armies in the Algerian War, gaining independence for their country. When attending a military college in Kętrzyn (Ger. Rastenburg) in 1966-1969, he actively opposed the Polish communist regime during the 1968 Polish political crisis, and as a result was expelled from the Officer School, and became a political prisoner for the first time. He continued his studies at the University of Silesia in Katowice, and after graduation was employed there as a lecturer,adiunct and researcher. In 1980-81, when Poland was swept by a wave of anti-communist strikes, and around ten million joined the anti-communist Solidarity trade union, Kopański co-founded a branch of this broad grassroots social movement at the University of Silesia.

Input: Consider Input: Question: What country was the first Islamic Missionary to reach the Sulu Archipelago from? Passage:Arab traders have been visiting Philippines for nearly 2000 years for trade purposes, and traded extensively with local Malayan chiefs, datos and Rajahs that had various Rajahnates in the region. Arab and Persian traders passed by the Philippines, on their way to Guangzhou, China. These early Arab traders followed the pre-Islamic religions of Arabian Christianity, Paganism and Sabeanism. After the advent of Islam, in 1380, Karim ul’ Makhdum, the first Islamic missionary to reach the Sulu Archipelago, brought Islam to what is now the Philippines, first arriving in Jolo. Subsequent visits of Arab Muslim missionaries strengthened the Islamic faith in the Philippines, concentrating in the south and reaching as far north as Manila. Starting with the conquest of Malaysia by the Portuguese and Indonesia by the Dutch, the Philippines began to receive a number of Malaysian-Arab refugees including several Malaysian princes and displaced court advisors. Soon, vast sultanates were established overlapping the existing indigenous Filipino barangay (village) governing system and Indianized royalty. The two largest were the Sultanate of Maguindanao, which loosely governed most of southern Mindanao and the Sultanate of Sulu, which included Basilan, Jolo, and parts of Borneo. Several other smaller but famous sultanates were also established such as the sultanate of Lanao in Mindanao, which was later conquered by the Spanish in the 16th century. The ties between the sultanates in Mindanao remained economically and culturally close to Indonesia, Brunei, and Malaysia until the end of the 19th century when the sultanates were weakened by the Spanish and later the American militaries.
