On to the Twentieth Century: The British extended their control over the peninsula by putting together the whole panoply of colonial administrationcivil service, public works, judiciary force, police force, post office, education, and land regulationwith teams of British administrators, teachers, engineers, and doctors to go with it. At the same time, the tin industry, dominated by Chinese using labor-intensive methods in the 19th century, passed increasingly into Western hands, who employed the modern technology of gravel pumps and mining dredges. Petroleum had been found in northern Borneo, at Miri, and in Brunei, and the Anglo-Dutch Shell company used Singapore as its regional depot for its oil supplies and exports. But the major breakthrough for the Malay economy was the triumph of rubber, when Singapore's new garden director, Henry Ridle ("Rubber Ridley" to his friends, "Mad Ridley" to all doubting Thomases) had developed new planting and tapping methods and painstakingly spread his faith in rubber around the peninsula. World demand increased with the growth of the motor-car and electrical industries, and sky-rocketed during World War I. By 1920, Malaya was producing 53 percent of the world's rubber, which had overtaken tin as its main source of income. The Malay ruling class again took a back seat. Together with effective control of the rubber and tin industries, the British now firmly held the reins of government. The sultans were left in charge of local and religious affairs, content with their prestige, prosperity, and security. The census of 1931 served as an alarm signal for the Malay national consciousness. Bolstered by a new influx of immigrants to meet the rubber and tin booms of the 1920s, non-Malays now slightly outnumbered the indigenous population. The Great Depression of 1929 stepped up ethnic competition in the shrinking job market, and nationalism developed to safeguard Malay interests against the Chinese and Indians rather than the British imperial authority. Though hampered by the peninsula's division into the States and the Straits Settlements, relatively conservative Muslim intellectuals and community leaders came together at the Pan-Malayan Malay Congress in Kuala Lumpur in 1939. In Singapore the following year, they were joined by representatives from Sarawak and Brunei. Teachers and journalists urged the revival of the common Malay-Indonesian consciousness, split by the Anglo-Dutch dismemberment of the region in the 19th century. This spirit became a factor in the gathering clouds of war.

Problem: To protect its seagoing interests and trade routes, Portugal established strategic garrisons in Goa (India), Malacca (East Indies), and Hormuz in the Persian Gulf. Portuguese explorers then embarked upon Macau (now Macao), the Congo, and various other parts of Africa, including the Sudan. The Portuguese policy was to avoid armed strife and to develop a trade empire, rather than to conquer nations. To this end it succeeded with relatively few blood-soaked episodes in its colonial history. Adventures abroad, however, proved disastrous during the second half of the 16th century. In 1557 the 14-year-old boy-king Sebastiao ascended the throne, the beginning of a calamitous reign that was to end at the battle of Alcacer-Quiber (Morocco) in pursuit of a vain crusade. Sebastiao's untimely demise, alongside some 18,000 ill-prepared, badly led followers, set the stage for a crisis of succession. For many years afterwards, legends and rumors bizarrely insisted that the king was still alive, and imposters turned up from time to time claiming the throne; those who were plausible enough to be deemed a threat were summarily executed. In fact, the only rightful claimant to the crown was the elderly Prince Henry. But after two years of alternating between the throne and his sickbed, he died, heirless. Surveying the situation and smelling an opportunity, Spain occupied the power vacuum, and Portugal's neighbor and long-time antagonist became its master. Spanish rule dictated Portugal's inadvertent involvement in Spain's ongoing wars. In 1587 a squadron of British ships commanded by Francis Drake attacked the Algarve (now a "legitimate target" as Spanish territory) and sacked Sagres, thus depriving the world of the relics of Henry the Navigator. Nine years later Faro was torched. The 1386 Treaty of Windsor, by which Britain and Portugal had pledged eternal friendship, seemed a distant memory. Portugal's empire was gradually eroded, and many of its trading posts (with the notable exception of Brazil) were picked off by the British and Dutch. Finally, after 60 years of Spanish rule, Portuguese noblemen (aided by the French, then at war with Spain) organized a palace coup and restored independence. The Great Disaster Portugal's greatest misfortune struck on All Saint's Day, 1 November 1755.

Question: "The death of Sebastiao and 18,000 followers was precipitated by what event?"

Input: (CNN) -- Shain Gandee, one of the stars of the MTV reality show "Buckwild," has been found dead along with two other people in Kanawha County, West Virginia, authorities said Monday. "This is a very sad and tragic event," Kanawha County Commissioner Kent Carper said. "We live in a very small community. Our thoughts and prayers are with the Gandee family." Gandee, 21, was found dead in a vehicle along with his uncle, David Dwight Gandee, 48, and Donald Robert Myers, 27, authorities said. 'Buckwild' producer talks about the show "Earlier this day after releasing information Shain Gandee was missing, the Kanawha County Sheriff's Office received word of a disabled vehicle in a wooded area near Thaxton Hollow, Sissonville, Kanawha County WV," said a statement from the Sheriff's Office. "Deputies and members of the Sissonville Volunteer Fire Department used all terrain vehicles to access that vehicle, a 1984 Ford Bronco belonging to the Gandee family. The vehicle was in a muddy area along a worn path. Inside were the bodies of three people." In a subsequent release, the Sheriff's Office said the vehicle was partially submerged in mud. It was uneven but upright; its muffler was below the surface. Mud covered the lower part of the Bronco's passenger side door, but the driver's side, where the younger Gandee sat, was free, the Sheriff's Office said. Gandee was happy with life before death He was one of the nine cast members of "Buckwild." The show follows a group of young adults trying to have fun in Sissonville, West Virginia, pulling stunts such as turning a dump truck into a swimming pool or just riding around the woods on their all-terrain vehicles. Gandee was billed as a former high school prom king who had done "every job from coal mining to being a garbage man."
