Example Input: The Glory of Melaka: In the early days, if you were not a pirate or a mosquito, Melaka was not much of a place to live. The land was infertile, just a swampy plain, the river small and sluggish. But it had a sheltered harbor, protected from the monsoons by neighboring Sumatra. Later, the strategic location and deep-water channel close to the coast brought in the bigger vessels of the trade-wind traffic crossing the Indian Ocean. The first to realize the larger commercial potential, as so often throughout the country's subsequent history, were the Chinese. In 1409, under a new directive from Emperor Chu Ti to pursue trade in the South Seas and the Indian Ocean, a Chinese fleet of 50 ships headed by Admiral Cheng Ho called in at Melaka. They made Parameswara an offer he could not refuse: port facilities and an annual financial tribute in exchange for Chinese protection against the marauding Thais. In 1411, Parameswara took the money to Beijing himself, and the emperor gratefully made him a vassal king. Twenty years later, the Chinese withdrew again from the South Seas trade. The new ruler of Melaka, Sri Maharajah, switched his allegiance to the Muslim trading fraternity by marrying into the Muslim faith, wedding the daughter of a sultan in Sumatra. Islam won its place in Malaya not by conquest — as had been the case in North Africa and Europe — but by trade, dynastic alliances, and peaceful preaching. Bengali peddlers had already brought the faith to the east coast. In Melaka and throughout the peninsula, Islam thrived as a strong, male-dominated religion of individuality, offering dynamic leadership and preaching brotherhood and self-reliance — all qualities ideally suited to the coastal trade. At the same time, Sufi mystics synthesized Islamic teaching with local Malay traditions of animistic magic and charisma, though Islam did not become the state religion until Muzaffar Shah became sultan of Melaka (1446–1459). But the key figure in the sultanate was Tun Perak, bendahara (prime minister) and military commander. He expanded Melaka's power along the west coast and down to Singapore and the neighboring Bintan islands. He also had orang laut pirates patrolling the seas to extort tribute from passing ships. After Ailied district chiefs had repelled assaults from Thai-controlled armies from Pahang, Tun Perak personally led a famous victory over a Thai fleet off Batu Pahat in 1456. <sep>Who was the leader who realized the commercial value of the port<sep>Thai peng

Example Input: Washington The Iraqi government has agreed to let U.S. Rep. Tony Hall visit the country next week to assess a humanitarian crisis that has festered since the Gulf War of 1990, Hall's office said Monday. The Dayton Democrat, who has traveled to other crisis points including Sierra Leone and North Korea, will spend three days visiting hospitals and other facilities to seek understanding why aid has been ineffective in stemming malnourishment and other medical problems. Iraq has been under economic sanctions since the war ended, which some say have thwarted the country's ability to recover from the devastation of the bombing campaign. The Persian Gulf War destroyed much of the country's medical infrastructure, according to a report by the World Health Organization. In 1996 the WHO found that much of the population existed in a state of ``semi-starvation.'' Hall will be only the second member of Congress to travel in Iraq since the war, according to Hall's office. The last visitor was then-U.S. Rep. Bill Richardson of New Mexico, who went to help a pair of U.S. oilmen in diplomatic trouble. Hall flies to Amman, Jordan, on Friday, where he'll spend the night before driving to Iraq. Flights are not permitted into Iraq. Hall is to return to Washington on April 22. Story Filed By Cox Newspapers <sep>Why is U.S. Rep. Tony Hall visiting Iraq?<sep>To assess a humanitarian crisis that has festered since the Gulf War of 1990, and to seek understanding why aid has been ineffective in stemming malnourishment and other medical problems
