Lisbon in the context of "Ernst von Glasersfeld"

Portugal, officially the Portuguese Republic, is a country on the Iberian Peninsula in Southwestern Europe. It is an unitary semi-presidential republic composed by continental Portugal and two autonomous regions, with Lisbon as both its capital and largest city. The continental portion borders Spain to the north and east, with Madeira and the Azores in the Atlantic Ocean. It features the westernmost point in continental Europe.

The western Iberian Peninsula has been continuously inhabited since prehistoric times, with the earliest signs of settlement dating to 5500 BC. Celtic and Iberian peoples arrived in the first millennium BC. The region came under Roman control in the second century BC. A succession of Germanic peoples and the Alans ruled from the fifth to eighth centuries AD. Muslims invaded mainland Portugal in the eighth century, but were gradually expelled by the Christian Reconquista, culminating with the capture of the Algarve between 1238 and 1249. Modern Portugal began taking shape during this period, initially as a county of the Christian Kingdom of León in 868, and formally as a sovereign kingdom with the Manifestis Probatum in 1179.

Fortaleza (/ˌfɔːrtəˈleɪzə/ FOR-tə-LAY-zə ; Brazilian Portuguese: [foʁtaˈlezɐ] ; Portuguese for 'Fortress') is the state capital of Ceará, located in Northeastern Brazil. It is Brazil's 4th largest city—Fortaleza surpassed Salvador in 2024 census with a population of slightly over 2.5 million—and 12th among cities with the highest gross domestic product. It forms the core of the Fortaleza metropolitan area, which is home to almost 4 million people.

Fortaleza is an important industrial and commercial center of Northeast Brazil. According to the Ministry of Tourism, it is the fourth most visited city and tourist destination in the country. The BR-116, the most important highway in the country, starts in Fortaleza. The municipality is part of the Mercosur common market, and vital trade port which is closest to mainland Europe, being 5,608 kilometres (3,485 mi) from Lisbon, Portugal.

Dom Pedro I (12 October 1798 – 24 September 1834), known in Brazil and in Portugal as "the Liberator" (Portuguese: o Libertador) or "the Soldier King" (o Rei Soldado) in Portugal, was the founder and first ruler of the Empire of Brazil from 1822 to 1831 (under the name of Pedro I) and King of Portugal in 1826 (under the name of Pedro IV).

Born in Lisbon, Pedro was the fourth child of King Dom John VI of Portugal and Queen Carlota Joaquina, and thus a member of the House of Braganza. When the country was invaded by French troops in 1807, he and his family fled to Portugal's largest and wealthiest colony, Brazil. The outbreak of the Liberal Revolution of 1820 in Lisbon compelled Pedro I's father to return to Portugal in April 1821, leaving him to rule Brazil as regent. He had to deal with challenges from revolutionaries and insubordination by Portuguese troops, all of which he subdued. The Portuguese government's threat to revoke the political autonomy that Brazil had enjoyed since 1808 was met with widespread discontent in Brazil. Pedro I chose the Brazilian side and declared Brazil's independence from Portugal on 7 September 1822. On 12 October, he was acclaimed Brazilian emperor and by March 1824 had defeated all armies loyal to Portugal. A few months later, Pedro I crushed the short-lived Confederation of the Equator, a failed secession attempt by provincial rebels in Brazil's northeast.

The High Representative of the Union for Foreign Affairs and Security Policy/Vice-President of the European Commission (HR/VP) is the chief co-ordinator and representative of the Common Foreign and Security Policy (CFSP) within the European Union (EU). The position is currently held by Kaja Kallas.

The Treaty of Amsterdam, signed in 1997 and entered into force in 1999, had established the position of High Representative for Common Foreign and Security Policy. The position's purview was augmented by the Treaty of Lisbon, signed in 2007 and entered into force in 2009, which established its current title and authorities, including a seat on the European Commission as Vice-President and the chair of the council of EU foreign ministers. The first person to hold the full title of High Representative of the Union for Foreign Affairs and Security Policy, inaugurated upon the coming into force of the Treaty of Lisbon, was Catherine Ashton. Early in the first term of the post, the office holder became assisted by the European External Action Service (EEAS) that was set up in December 2010.

The Spanish Armada (often known as Invincible Armada, or the Enterprise of England, Spanish: Grande y Felicísima Armada, lit. 'Great and Most Fortunate Navy') was a Spanish fleet that sailed from Lisbon in late May 1588, commanded by Alonso de Guzmán, Duke of Medina Sidonia, an aristocrat without previous naval experience appointed by Philip II of Spain. His orders were to sail up the English Channel, join with the army of Alexander Farnese, Duke of Parma in Flanders, and escort an invasion force that would land in England and overthrow Elizabeth I. Its purpose was to reinstate Catholicism in England, end English support for the Dutch Republic in the north and prevent attacks by English and Dutch privateers against Spanish interests in the Americas.

The Spanish were opposed by an English fleet based in Plymouth. Faster and more manoeuvrable than the larger Spanish galleons, its ships were able to attack the armada as it sailed up the Channel. Several subordinates advised Medina Sidonia first to enter Plymouth Sound and attack the English fleet before it could leave harbour and then to anchor in the Solent and occupy the Isle of Wight, but he refused to deviate from his instructions to join with Parma. Although the armada reached Calais largely intact, while awaiting communication from Parma, it was attacked at night by English fire ships and forced to scatter. The armada suffered further losses in the ensuing Battle of Gravelines and was in danger of running aground on the Dutch coast when the wind changed, allowing it to escape into the North Sea. Pursued by the English, the Spanish ships returned home via Scotland and Ireland. Up to 24 ships were wrecked along the way before the rest managed to get home. Among the factors contributing to the defeat and withdrawal of the armada were bad weather conditions and the better employment of naval guns and battle tactics by the English.

The capture of Gibraltar by Anglo-Dutch forces of the Grand Alliance occurred between 1 and 4 August 1704 during the War of the Spanish Succession. Since the beginning of the war the Alliance had been looking for a harbour in the Iberian Peninsula to control the Strait of Gibraltar and facilitate naval operations against the French fleet in the western Mediterranean Sea. An attempt to seize Cádiz had ended in failure in September 1702, but following the Alliance fleet's successful raid in Vigo Bay in October that year, the combined fleets of the "Maritime Powers", the Netherlands and England, had emerged as the dominant naval force in the region. This strength helped persuade King Peter II of Portugal to sever his alliance with France and Bourbon-controlled Spain, and ally himself with the Grand Alliance in 1703 as the Alliance fleets could campaign in the Mediterranean using access to the port of Lisbon and conduct operations in support of the Austrian Habsburg candidate to the Spanish throne, the Archduke Charles, known to his supporters as Charles III of Spain.

Prince George of Hesse-Darmstadt represented the Habsburg cause in the region. In May 1704 the prince and admiral George Rooke, commander of the main Grand Alliance fleet, failed to take Barcelona in the name of "Charles III"; Rooke subsequently evaded pressure from his allies to make another attempt on Cádiz. In order to compensate for their lack of success the Alliance commanders resolved to capture Gibraltar, a small town on the southern Spanish coast. Following a heavy bombardment the town was invaded by English and Dutch marines and sailors. The governor, Diego de Salinas, agreed to surrender Gibraltar and its small garrison on 4 August. Three days later Prince George entered the town with Austrian and Spanish Habsburg troops in the name of Charles III of Spain. The Grand Alliance failed in its objective of replacing Philip V with Charles III as King of Spain, but in the peace negotiations Gibraltar was ceded to Britain.

The Second Crusade (1147–1149) was the second major crusade launched from Europe. The Second Crusade was started in response to the fall of the County of Edessa in 1144 to the forces of Zengi. The county had been founded during the First Crusade (1096–1099) by the future King Baldwin I of Jerusalem in 1098. While it was the first Crusader state to be founded, it was also the first to fall.

The Second Crusade was announced by Pope Eugene III, and was led in the east by European kings Louis VII of France and Conrad III of Germany, with help from a number of other European nobles. The armies of the two kings marched separately across Europe. After crossing Byzantine territory into Anatolia, both armies were separately defeated by the Seljuk Turks. The main Western Christian source, Odo of Deuil, and Syriac Christian sources claim that the Byzantine Emperor Manuel I Komnenos secretly hindered the crusaders' progress, particularly in Anatolia, where he is alleged to have deliberately ordered Turks to attack them. However, this alleged sabotage of the Crusade by the Byzantines was likely fabricated by Odo, who saw the Empire as an obstacle; moreover, Emperor Manuel had no political reason to do so. Louis and Conrad reached Jerusalem in 1148, where the remnants of their armies participated in an ill-advised attack on Damascus that ended in their retreat. Crusader efforts were successful in Iberia, where several territories—including Lisbon, the future capital of the Portuguese Empire—were conquered.

Jan van Eyck (/væn ˈaɪk/ van EYEK; Dutch: [ˈjɑɱ vɑn ˈɛik]; c. before 1390 – 9 July 1441) was a Flemish painter active in Bruges who was one of the early innovators of what became known as Early Netherlandish painting, and one of the supreme figures of the Early Northern Renaissance. Such was his legacy, that he has been called “the inventor of oil-painting” by Vasari, Ernst Gombrich, and others, although this claim is now considered an oversimplification.

Surviving records date his birth at around 1380 or 1390, in Maaseik (then Maaseyck, hence his name), Limburg, which is located in present-day Belgium. He took employment in The Hague around 1422, when he was already a master painter with workshop assistants, and was employed as painter and valet de chambre to John III the Pitiless, ruler of the counties of Holland and Hainaut. Some time after John's death in 1425, he was appointed as court painter to Philip the Good, Duke of Burgundy, and worked in Lille before moving to Bruges in 1429, where he lived until his death. He was highly regarded by Philip, and was dispatched on several diplomatic visits abroad, including one to Lisbon in 1428 to discuss the possibility of a marriage contract between the duke and Isabella of Portugal.

The Community of Portuguese Language Countries (Portuguese: Comunidade dos Países de Língua Portuguesa; abbr. : CPLP), also known as the Lusophone Commonwealth or Lusophone Community (Portuguese: Comunidade Lusófona), is an international organization and political association of Lusophone nations across four continents, where Portuguese is an official language. The CPLP operates as a privileged, multilateral forum for the mutual cooperation of the governments, economies, non-governmental organizations, and peoples of the Lusofonia. The CPLP consists of 9 member states and 34 associate observers, located in Africa, América, Asia, Europe and Oceania, totalling 39 countries and 4 organizations.

The CPLP was founded in 1996, in Lisbon, by Angola, Brazil, Cabo Verde, Guinea-Bissau, Mozambique, Portugal, and São Tomé and Príncipe, nearly two decades after the beginning of the decolonization of the Portuguese Empire. Following the independence of East Timor in 2002 and the application by Equatorial Guinea in 2014, both of those countries became members of the CPLP. Galicia (an autonomous community of Spain), Macau (a special administrative region of China), and Uruguay are formally interested in full membership and another 17 countries across the world are formally interested in associate observer status.
