=﻿What was the Kingdom of Portugal?=

The Kingdom of Portugal was a political estate in the west of the Iberian Peninsula (Europe) between the years 1139 and 1910 a.D. It became important mainly because the Portuguese were the first to sail to **India** by sea, surrounding the southern tip of **Africa** and discovering a new trading route. They were looking for spices (apart from conquering lands, spreading Christianity, etc.). See **'Comercial reasons'**.

=﻿Reasons for the explorations:=

Religious reasons

 * The Portuguese wanted to **spead christianity**.

Comercial reasons

 * They needed to find **new trade routes to the spices** land (in India) because the Turks (Muslims) had conquered the Byzantine Empire and had taken the control of the route of the spices (which was called the trade route of silk). Spices were very important in the Middle and Modern Ages because they were only way of preserving food, specially meat.




 * Cosequently, the europeans had to pay heavy taxes to get to the spices.
 * There was a political interest against the Crown of Castile and a militar interest against the **Muslims**.
 * During the 15th century, the Portuguese suffered a **financial crisis**, reason for the eagernes of getting gold and slaves from Sudan.

Intelectual reasons

 * The Renaissance men were **very adventurous** and they wanted to know more and more every day.
 * Henry the Navigator (a Portuguese nobleman who promoted the first expeditions to Africa) had **good economic means** at his disposal, and stablished in Sagres (cape of San Vicente) a **center of nautical, geographical and cosmographic studies** with Majorcan geographers and Italian sailors. The work in Sagres was promoted specially by the scientific curiosity**.**

Technical reasons
▪ The **compass**: it has two needles which are always pointing to the north and to the south. It is used to locate your position on the Earth. This way, ships could move farther from the coast.
 * ** Navigational instruments ** that helped the orientation during navigation were created:



▪ The **rudder**: it is an articulated piece of wood or metal used to steer a ship.



▪ The **astrolabe**: it is an object used to locate your position on Earth thanks to the orientation of the stars.


 * ** Ships were improved, ** like the caravel, which could transport more people and cargo and travel faster and more distances
 * ** Portulan charts ** were created. They showed the coastline, the obstacles at sea and the best natural ports.



Other reasons

 * ** The portuguese army was expert ** because it had been fighting during the Reconquest of the Iberian Peninsula and the Kingdom of Portugal was on an excellent geographical position for exploring.
 * **The portuguese thought that there was a Chistian Kingdom in the south of Africa**, governed by a king called Prestor John . They wanted to become his allies and conquer together the Islamic Empire.

=The first years of explorations=

Between 1385 and 1433 **Juan de Avis** (Juan I or John I) governed in Portugal. He promoted politics of expansion, inluding maritime, starting the intervention in Africa, leaded by his son Henry the Navigator 's initiative. He opened the Portuguese expansion with the conquest of **Ceuta (1415).**



The taking of Ceuta meant the possession of a good place to fight against Muslim pirates, and was also an entrance to the Mediterranean Sea and the north of Africa, apart fom being an important point for channeling the Portuguese trade with Morocco and a base for avoidig Castilian expansion in this country and the Atlantic Ocean.

=﻿Prince Henry the Navigator=

Henry the Navigator
 * Prince Henry the Navigator** (1394-1460) was the son of the Portuguese king Juan I (or John I), although he never got the reign, because he had two elder brothers, Edward (later Edward I) and Pedro. He is very important because he **supported a lot of expeditions** to Africa along his life, although he **never sailed** in his explorations.

=The treaty of Alcaçobas=

The rivalry between the **Crown of Castile** and the **kingdom of Portugal** for the possession of the **Canary Islands** and the monopoly of trade in the **coast of Guinea** obliged the Portuguese and Castilian monarchs to **stablish an agreement,** signed by: Isabel I of Castile, Ferdinand II of Aragon, Alfonso V of Portugal and Joao, prince of Portugal.

The **treaty of Alcaçobas (1479)** gave the Portuguese free rain to continue their explorations along the African coast and the rights in some african kingdoms, while the Castilians received the Canary Islands. It also prohibited Castilians sailing among the Portuguese possesions without their permission.

The **treaty of Alcaçobas** established Castilian and Portuguese control in the Atlantic Ocean and settled, for a while, a period of hostility. It is true that Castilians won the Canary Islands but, while the Portughuese where making their explorations, the kingdom of Castile decided to find new routes to Asia and the spices without entering places under their control (Africa and part of the Atlantic Ocean).
