Today we take for granted that the world is round. In the fifteenth century, however, most people believed the world was flat. They thought that monsters or a trip over the edge of the earth waited for anybody who sailed outside the limits of known territory. People laughed at or jailed others who dared think that the world was in the shape of a globe.
There were educated persons, however, who reasoned that the world must be round. An Italian named Christopher Columbus was bold enough to push this notion, and ask for money to explore the seas, and find what he thought would be the other hemisphere of the earth. Portugal, Italy and England refused to support such a venture.
At that time, spice merchants were looking for an easier route to Asia. They traveled south past Africa, around the Cape of Good Hope, and continued eastward. Christopher Columbus convinced Queen Isabella of Spain that it would be easier to sail directly west and find the rich treasures of India and Asia. A new route would be found, he said, and possible new lands for Spain.
Columbus first asked Queen Isabella for help in 1486, but it was years before she agreed... provided that he conquer some of the islands and mainland for Spain. Columbus would also be given the title of "Admiral of All the Ocean Seas," and receive one-tenth of the riches that came from any of his discoveries.
Finally, on August 3, 1492, he and ninety men set sail on the flagship Santa Maria. Two other ships, the Nina and the Pinta, came with him. They sailed west. Three long months went by. His men became tired and sick, and threatened to turn the ships back. Columbus encouraged them, certain that they would find the spice trail to the East. On October 11th, ten o'clock at night, Columbus saw a light. The Pinta kept sailing, and reported that the light was, in fact, land. The next morning at dawn they landed.
Christopher Columbus and his crew had expected to see people native to India, or be taken to see the great leader Khan. They called the first people they saw "Indians." They had gone ashore in their best clothes, knelt and praised God for arriving safely. From the "Indians" they learned that the island was called Guanahani. Columbus christened it San Salvador and claimed it immediately for Spain. When they landed on the island that is now Cuba, they thought they were in Japan. After three subsequent voyages, Columbus was still unenlightened. He died a rich and famous man, but he never knew that he discovered lands that few people had imagined were there.
Columbus had stopped at what are now the Caribbean Islands, either Watling Island, Grand Turk Island, or Samana Cay. In 1926, Watling Island was renamed San Salvador and acknowledged as the first land in the New World. Recently, however, some people have begun to dispute the claim. Three men from Miami, Florida have started a movement to recognize Conception Island as the one that Columbus and his men first sighted and landed on. The controversy has not yet been resolve.
Few celebrations marked the discovery until hundreds of years later. The continent was not even named after Columbus, but an Italian explorer named Amerigo Vespucci. In 1792, a ceremony was held in New York honoring Columbus, and a monument was dedicated to him. Soon after that, the city of Washington was officially named the District of Columbia and became the capital of the United States. In 1892, a statue of Columbus was raised at the beginning of Columbus Avenue in New York City. At the Columbian Exposition held in Chicago that year, replicas of Columbus's three ships were displayed.
Americans might not have a Columbus Day if Christopher Columbus had not been born in Italy. Out of pride for their native son, the Italian population of New York City organized the first celebration of the discovery of America on October 12, 1866. The next year, more Italian Organizations in other cities held banquets, parades and dances on that date. In 1869, when Italians of San Francisco celebrated October 12, they called it Columbus Day.
In 1905, Colorado became the first state to observe a Columbus Day. Over the next few decades other states followed. In 1937, then- President Franklin Roosevelt proclaimed every October 12 as Columbus Day. Since 1971, it has been celebrated on the second Monday in October.
Although it is generally accepted that Christopher Columbus was the first European to have discovered the New World of the Americas, there is still some controversy over this claim. Some researchers and proponents of other explorers attribute the first sightings to the early Scandinavian Vikings or the voyages of Irish missionaries which predate the Columbus visit in 1492. The controversy may never be fully resolved to everyone's satisfaction, but 1992 marked the 500th anniversary of the Columbus discovery.
the argument:
In 986, Norwegian-born Eirik Thorvaldsson, known as Eirik the Red, explored and colonized the southwestern part of Greenland. It was his son, Leiv Eiriksson, who became the first European to set foot on the shores of North America, and the first explorer of Norwegian extraction now accorded worldwide recognition.
The date and place of Leiv Eiriksson's birth has not been definitely established, but it is believed that he grew up on Greenland. The Saga of Eric the Red relates that he set sail for Norway in 999, served King Olav Trygvasson for a term, and was sent back to Greenland one year later to bring Christianity to its people.
There are two schools of thought as to the subsequent course of events. One of these is that Eiriksson, en route for Greenland, came off course, and quite by chance came to the shores of northwestern America in the year 1000, thus preceding Columbus by nearly 500 years. However, according to the Greenland Saga, generally believed to be trustworthy, Eiriksson's discovery was no mere chance. The saga tells that he fitted out an expedition and sailed west, in an attempt to gather proof of the claims made by the Icelandic trader Bjarni Herjulfsson. In 986 Herjulfsson, driven far off course by a fierce storm between Iceland and Greenland, had reported sighting hilly, heavily forested land far to the west. Herjulfsson, though believably the first European to see the continent of North America, never set foot on its shores. Leiv Eiriksson, encouraged by the current talk of potential discoveries, and the constant need of land to farm, bought Bjarni's ship and set off on his quest of discovery.
He appears to have followed Bjarni's route in reverse, making three landfalls. The first of these he named Helluland, or Flat-Stone Land, now generally regarded as having been Labrador. The second was Markland, or Wood Land, possibly Newfoundland. The exact location of the third, which was named Vinland, is a matter of scholastic controversy, but it could have been as far north as northern Newfoundland or as far south as Cape Cod or even beyond this.
Eiriksson and his men spent the winter in Vinland, at a place they named Leifsbud-ir, returning to Greenland the following year, 1001.
It was left to Eiriksson's brother, Thorvald to make the next voyage to the new-found territory, for strange as it may seem, Leiv Eiriksson never returned there. Subsequent attempts at settlement of Vinland were unsuccessful, due to strong friction between the Viking settlers and the native North Americans.
Though many still regard Christopher Columbus as the discoverer of the New World, Eiriksson's right to this title received the stamp of official approval in the USA when in 1964 President Lyndon B. Johnson, backed by a unanimous Congress, proclaimed October 9th "Leif Ericson Day" in commemoration of the first arrival of a European on North American soil.
The ridiculous:
Students, faculty and staff gathered at noon yesterday on Ho Plaza in a rally against the celebration of Columbus Day this Monday.
The flyers stated the crimes of Christopher Columbus to be the murder of more than 12 million Indians, the kidnapping and illegal transportation of African people and the depopulation of thirty Caribbean islands.

The Transform Columbus Day Alliance vowed Monday to disrupt any march this weekend that honors Christopher Columbus, and announced two events that group leaders say will transform the annual parade into a celebration of all cultures.
"If there is a parade honoring Christopher Columbus, there will be opposition to those efforts," said Morris, who compared the legacy of Columbus to the Nazis and American slavery. "Cultural celebrations need not be hateful, they need not be divisive, they need not be destructive."
