Home http://www.thornr.demon.co.uk/kchrist/phenry.html All his life, Prince Henry of Portugal was trying to find a sea route to India. He did not actually sail on an expedition, but he sponsored many of them. He started a navigational school and trained many sea captains. His captains discovered 4000 miles of the African coast. 38 years after his death a Portuguese ship found India by his route.

__Discoveries__
 * Two men who worked for Prince Henry found an island that they named "Porto Santo" which rabbits took over.
 * The same 2 men discovered another island which they named "Madeira" which means wood, and trees took over on Madeia.
 * Prince Henry discoverd 2,000 miles of the "unknown" and put it on the maps.
 * Prince Henry and other men designed the "Caravel" and they designed it from the "Caravela" and ancient Arab ships.
 * It took 14 voyages over 12 years until a ship finally got to the equator.
 * Bartolemeu Prestello who worked for Prince Henry is realated to Columbus.
 * Gil Eanes was the first to round Cape Bojador in 1434. How he did it was he sailed far out to sea before he got to Cape Bojador and came back in after he had passed it. He then avoided the fierce northeast winds and dangerous currents.

How you use an astrolabe is you move the inner circle and the arm until it shows what the sky looks like and it will tell you the local time and your latitude. His name in his native tongue (Portuguese) is Dom Henrique. On a Portuguese map dated 1424 there appear to be parts of America shown, so it is possible that someone other than Columbus discovered America.

__**Timeline**__ 1394-Prince Henry is born on March 4, in Oporto, Portugal. 1415-The Portuguese capture Ceuta, Morocco. 1416-Prince Henry starts his school for navigation. 1420-The Portuguese discover Madeira. 1424-25-Prince Henry starts the colonization of the Madeiras and attempts to purchase the Canaries. 1427-They discover the Azores. 1434-They sail past Cape Bojador. 1444-The African slave trade is enlarged by Henry. 1460-Prince Henry dies in Vila do Infante, Portugal. 1492-Columbus sails thousands of miles and finds America and thinks it is India. 1498-Vasco de Gama finds India by boat.

Before Prince Henry had a sailor get past Cape Bojador, the Portugese thought that because the waters froze in the north they boiled in the south. Sailors of that day sailed close to shore and in daylight because they couldn't navigate well away from shore. Why the sailors couldn't sail away from shore was they needed the shore so that they could see where they were and where they were going. There were no very accurate maps, so it was not very safe to sail far from shore. Portugal traded a lot by sea because they had so many ports and so much coastline (500 miles). Because of the extensive coastline of Portugal two industries developed. The two industries were shipbuilding and fishing. Before the 15th century the Europeans had almost no accurate information on geography and they got exposed to some of the accurate information and they wanted more, so in the 15th century it was a time of many expeditions. How the Europeans were exposed to accurate information is they got Ptolemy's book, //Guide to Geography// and trading.
 * __Portugal in the 15th Century__**

When Europeans colonized a place it would usually change the environment a lot. When the Portuguese colonized Porto Santo one of the crew brought a pregnant rabbit with them. The rabbit and its relations gobbled up everything including the crops which meant that the Portuguese fled back to Portugal to tell Prince Henry. Prince Henry was interested in vacant islands and had his explorers find another, Madeira. On Madeira they planted grape vines. The vines flourished and that meant that the Portuguese could make Madeira wine out of the grapes. Prince Henry had sugarcane plants imported to the Madeira islands and this caused a chain reaction. First, only rich people could afford sugar. Then there was more, so the price of it went down and then more people had it, so the demand went up. Later, because of the high demand, settlers on Caribbean islands grew sugarcane and had slaves tend it. So, in a way, Prince Henry made the slave trade grow.
 * __Colonization__**

Prince Henry's father approved of learning and his brothers read extensively and each wrote their own books. Now one knows if Henry did too. He probably didn't write any books, for none have survived.
 * __Younger life__**

__**Later life**__ In 1436 Prince Henry let his brother die in captivity instead of giving up Cueta.
