Krakatoa (August 27th)
By 1883, the area surrounding Krakatoa had been having seismic activity around the volcanoes for several years, some were so strong, they were felt as far off as Australia. In May of that year, steam began regularly venting from Perbowatan, and small eruptions of ash reached altitudes of 20,000 ft. By the end of May, all activity had died down, but the volcanoes began erupting again around June 16th, covering the island in a black cloud. The eruptions reached their highest level of intensity on August 25th, and by the 26th, it was evident that a greater eruption was yet to come.
On August 27th, 1883, four explosions occurred on the small island of Krakatoa. At 5:30am, Perboewatan volcano erupted, creating tsunamis going North. At 6:44am, Danan volcano exploded, sending tsunamis both East and West. At 10:02am, the largest explosion took place, and was heard 3,110 km south in Perth, Australia and 4,800km west in Mauritius, where the sound was mistaken for distant cannon fire. The energy released in this explosion alone was said to be equal to 200 megatons of TNT, or four times the energy created by the Tsar Bomba, the most powerful thermonuclear weapon ever detonated.
At 10:41am, a landslide on Rakata volcano caused the fourth and final eruption. The pressure created by the last explosion radiated out from the volcano at 1,086 km/h (675mph). The blast was so powerful, it blew out the eardrums of sailors in ships nearby. The pressure also caused a 2 and a half inch spike of mercury in pressure gauges in Batavia, and records from barographs around the world continued to pick up the volcano's shock-wave for the next five days. From these records, it has been concluded that the last eruption's shock-wave reverberated around the world seven times in total.
Hot ash from the volcano fell in Ketimbang in Sumatra later on the 27th, and approximately 1,000 people died. On the nearby island of Sebesi, only 13km off from the volcano, 3,000 were killed. Many settlements in the area were destroyed by the 30m tall tsunami. Smaller waves caused by the volcano were recorded as far away as the English Channel.
The volcanic ashed forced into the atmosphere by the eruption lowered the earth's temperature by 1.2 degrees Celsius, and it took five years for the temperature to return to normal. This ash also caused the sky to redden around the world. In New York, it was said that the sky was so red, many believed that there was a fire. In other areas, a Bishop's ring, or halo, formed around the sun.

#01- Marco Polo
In 1260, two Venetian merchants, Maffeo and Nicolo Polo, made their way East, to the palace of Kublai Khan, the Emperor of the Mongols. When they made it to the capital of the Mongol Empire, Kublai Khan was most hospitable and when he sent them away, he also sent a letter to Pope Clement IV, asking for 100 learned men to teach on Christianity. Although the Pope did not send the men, he sent a letter and precious gifts back to Asia in 1271 with Nicolo, Maffeo, and Marco Polo (1254-1324), Nicolo's son. Marco Polo soon became a favorite of the Great Khan's and went on several special missions to China, Burma, and India during his 17 years in the Khan's court. After coming back to Venice in 1294, Polo served in a war against the city of Genoa, and was captured. During his year in prison, Marco dictated an account of his time in Asia to Rustichello of Pisa, a writer of romances. The book was published and is now known as The Description of the World or The Travels of Marco Polo. Although Polo's book was accused of being full of lies, which it probably was, the book was read all over Europe. After he was set free, Polo was still left with some precious items from Asia. These items and Polo's book inspired and basically started the Age of Exploration. Marco Polo is the Number 1 explorer because his book and items from Asia almost fully started the Age of Exploration in Europe and inspired some of the other great explorers, such as the well-known Christopher Colombus.

In 1502, Da Gama returned to India with 20 ships and captured the cities of Calicut and Goa for Portugal, bringing many treasures back upon his return. After becoming a count in 1519, Da Gama was appointed as the Viceroy of India in 1524, and traveled to Goa once more. Vasco da Gama is celebrated as the explorer to find an ocean route to Asia from Europe and for capturing Calicut and Goa for Portugal.

#08- Zheng He
Zheng He (1371-1433), or Cheng Ho, was a Chinese navigator during the reign of the Ming Dynasty. Born Ma He, he came from an Arabian family that had come to China. When the Ming Dynasty conquered Zheng He's province, he was taken to the palace and became a court eunuch. HE gained a government position by helping Zhu Yuanzhang defeat the Yuan Dynasty. After the Ming Dynasty was given the throne, Zheng He was given command of the Chinese Navy. In 1402, Emperor Cheng Zu dispatched Zheng He to lead a large fleet to the Western Sea (Southeast Asia). From 1405 to 1433, Zheng He led his fleet of fifty to sixty ship and his crew of 27,000 people to explore the west in 7 different expeditions. In these trips, Zheng He made his way to India, the Middle East, and even Africa, and wherever he went, the sheer size of his ships and his fleet amazed the cultures he passed. During these trips, Zheng He found materials, fuels, and exotic animals to bring back to China. Zheng He accomplished much on the voyages he led, including giving China contact with western cultures, supplying China with many luxuries, and leading one of China's largest and greatest sea expeditions ever.

#09- Bartholomeu Dias
Bartholomeu Dias (c.1450-1499) was a Portuguese explorer who came from the family of Joao Dias, who sailed around Cape Bojador, and Diniz Dias, who discovered the Cape Verde Islands. In 1481, Bartholomeu joined Diego d'Azambuja to explore the Gold Coast of Africa. In 1486, King John II of Portugal appointed Dias to lead an expedition to find the southern tip of Africa and try to make contact with Prester John, the legendary Christian ruler of the East. With three ships, Dias sailed down the coast of Africa. During a storm, Dias passed around the southern tip of Africa and named it the Stormy Cape.Though Dias went back to Portugal soon after he went around the Stormy Cape, the information he brought home brought hope to many explorers, and the cape was later named the Cape of Good Hope. His charts helped explorers like Pedro Cabral and Vasco da Gama find their way to India. Dias will be remembered as the explorer who found the tip of Africa, gave explorers hope of finding a passage to India, and pushing Portugal into the front of the Age of Exploration. Although Dias did find the way to India, he never made it there. He sailed with Pedro Cabral on a trip to India, but drowned in a storm at the very cape that he had discovered.

#14- Pedro Alvarez Cabral
14 Pedro Cabral
Pedro Alvarez Cabral (1467-1520) was a Portugese explorer during the reign of King John II. King John appointed Cabral to sail arround the Cape of Good Hope and go to the Indies. With 13 ships, Cabral left Lisbon in 1500, with many men including Bartholemeu Dias, the explorer who had found the Cape of Good Hope. After sailing through the Cape Verdes Islands, Cabral found Brazil. Because Cabral thought that South America was an island, he named the land Vera Cruz (The True Cross). The brazilwood that Cabral found in Brazil contained a red dye. Cabral's men named the dye Terra de Brasil, from which the name Brazil came from. From South America, Cabral went towards the Cape of Good Hope. On May 24, 1500, a storm broke out at the cape, sinking the ship of Bartholemeu Dias. In September, Cabral arrived in Calcut, and Cabral brought many spices back from India. Cabral earns greatness for finding and naming Brazil, as well as going straight from South America to India.
