Problem: Background: The Chimu culture was centered on Chimor with the capital city of Chan Chan, a large adobe city in the Moche Valley of present-day Trujillo, Peru. The culture arose about 900. The Inca emperor Topa Inca Yupanqui led a campaign which conquered the Chimu around 1470. This was just fifty years before the arrival of the Spanish in the region.
Context: The mature Chimu culture developed in roughly the same territory where the Mochica had existed centuries before. The Chimu was also a coastal culture. It was developed in the Moche Valley north of present-day Lima, northeast of Huarmey, and finishing in central present-day Trujillo. Later, it expanded to Arequipa. The Chimu appeared in the year 900: Chimor, also known as the Kingdom of Chimor, had its capital "at the great site now called Chanchan, between Trujillo and the sea, and we may assume that Taycanamo founded his kingdom there. His son, Guacri-caur, conquered the lower part of the valley and was succeeded by a son named Nancen-pinco who really laid the foundations of the Kingdom by conquering the head of the valley of Chimor and the neighboring valleys of Sana, Pacasmayo, Chicama, Viru, Chao and Santa." The estimated founding date of the last Chimu kingdom is in the first half of the 14th century. Nacen-pinco was believed to have ruled around 1370 and was followed by seven rulers whose names are not yet known. Minchancaman followed these rulers, and was ruling around the time of the Inca conquest (between 1462 and 1470). This great expansion is believed to have occurred during the late period of Chimu civilization, called: Late Chimu, but the development of the Chimu territory spanned a number of phases and more than a single generation. Nacen-pinco, "may have pushed the imperial frontiers to Jequetepeque and to Santa, but conquest of the entire region was an agglutinative process initiated by earlier rulers." (17) The Chimu expanded to include a vast area and many different ethnic groups. At its peak, the Chimu advanced to the limits of the desert coast to the valley of the Jequetepeque River in the north. Pampa Grande in the Lambayeque Valley was also ruled by the Chimu. To the south, they expanded as far as Carabayallo. Their expansion southward was stopped by the military power of the great valley of Lima. Historians and archeologists contest how far south they managed to expand.
Question: Did they have to use force in order to expand?
Answer: Guacri-caur, conquered the lower part of the valley

Problem: Background: Leonard, the fifth of seven children of Cicero and Getha Leonard, was born in Wilmington, North Carolina. He was named after Ray Charles, his mother's favorite singer. The family moved to Washington, D.C., when he was three, and they settled permanently in Palmer Park, Maryland when he was ten. His father worked as a supermarket night manager and his mother was a nurse.
Context: On November 7, 1988, Leonard made another comeback, facing Don Lalonde at Caesar's Palace in Las Vegas. They fought for Lalonde's WBC Light Heavyweight Championship and the newly created WBC Super Middleweight Championship, which meant that Lalonde had to make 168 lbs. Many were critical of Leonard for stipulating that his opponent--a natural 175 pounder--should weigh less than his usual fighting weight, which could possibly weaken him. However, Lalonde later told HBO's Larry Merchant that he didn't have any trouble making weight. Lalonde, 31-2 with 26 knockouts, was guaranteed at least $6 million and Leonard was guaranteed over $10 million. This would be Leonard's first professional fight without Angelo Dundee. For Leonard's fight with Hagler, Dundee worked without a contract and received $175,000, which was less than 2% of Leonard's purse. Dundee was unhappy with that amount. He requested a contract for the Lalonde fight and Leonard refused. "I don't have contracts. My word is my bond", Leonard said. Janks Morton and Dave Jacobs trained Leonard for the Lalonde fight. Lalonde's size and awkwardness troubled Leonard. In the fourth round, a right hand to the top of Leonard's head dropped him for just the second time in his career. Early in the ninth, Lalonde hurt Leonard with a right to the chin. Leonard fired back and hurt Lalonde with a right. He drove him to the ropes and unleashed a furious assault. Lalonde tried to tie up Leonard, but got dropped with a powerful left hook. He rose but was soon down again, and the fight was stopped. Judges Chuck Giampa and Franz Marti had Leonard ahead by scores of 77-74 and 77-75, respectively. Judge Stuart Kirshenbaum had Lalonde ahead 76-75. After the fight, Leonard vacated the light heavyweight title, but kept the super middleweight title. Also, Leonard and Janks Morton split because of personal differences. Morton was replaced as co-trainer by Pepe Correa, who had worked with Leonard for most of the previous fifteen years.
Question: what was his greatest accomplishment?
Answer:
After the fight, Leonard vacated the light heavyweight title, but kept the super middleweight title.
