Charles VI Of France
Charles VI (3 December 136821 October 1422), nicknamed the Beloved (french: le Bien-Aimé) and later the Mad (french: le Fol or ''le Fou''), was King of France from 1380 until his death in 1422. He is known for his mental illness and psychotic episodes that plagued him throughout his life. He ascended the throne at the young age of eleven, his father leaving behind a favorable military situation, marked by the reconquest of most of the English possessions in France. First placed under the regency of his uncles, the Dukes of Burgundy, Anjou, Berry, and Bourbon, Charles decided in 1388, aged 20, to emancipate himself. In 1392, while leading a military expedition against the Duchy of Brittany, the king had his first attack of delirium, during which he attacked his own men in the forest of Le Mans. A few months later, following the Bal des Ardents (January 1393) where he narrowly escaped death from burning, Charles was again placed under the regency of his uncles, the dukes of ...

Treaty Of Troyes
The Treaty of Troyes was an agreement that King Henry V of England and his heirs would inherit the French throne upon the death of King Charles VI of France. It was formally signed in the French city of Troyes on 21 May 1420 in the aftermath of Henry's successful military campaign in France. It forms a part of the backdrop of the latter phase of the Hundred Years' War finally won by the French at the Battle of Castillon in 1453, and in which various English kings tried to establish their claims to the French throne. Terms The treaty arranged for the marriage of Charles VI's daughter Catherine of Valois to Henry V, who was made regent of France and acknowledged (along with his future sons) as successor to the French throne. The Dauphin Charles VII of France was disinherited from the succession. The Estates-General of France ratified the agreement later that year after Henry V entered Paris. Background The French king Charles VI suffered bouts of insanity through much of his r ...

Henry V Of England
Henry V (16 September 1386 – 31 August 1422), also called Henry of Monmouth, was King of England and Lord of Ireland from 1413 until his death in 1422. Despite his relatively short reign, Henry's outstanding military successes in the Hundred Years' War against France made England one of the strongest military powers in Europe. Immortalised in Shakespeare's " Henriad" plays, Henry is known and celebrated as one of the greatest warrior-kings of medieval England. During the reign of his father Henry IV, Henry gained military experience fighting the Welsh during the revolt of Owain Glyndŵr and against the powerful aristocratic Percy family of Northumberland at the Battle of Shrewsbury. Henry acquired an increased role in England's government due to the king's declining health, but disagreements between father and son led to political conflict between the two. After his father's death in 1413, Henry assumed control of the country and asserted the pending English clai ...

1420 Caldera Earthquake
The 1420 Caldera earthquake shook the southern portion of Atacama Desert on September 1 and caused tsunamis in Chile as well as Hawaii and the towns of Japan. The earthquake is thought to have had a size of 8.8–9.4 . Historical records of the tsunami exist for the Japanese harbours of Kawarago and Aiga where confused residents saw the water recede in the morning of September 1, without any sign of an earthquake. In Chile, rockfalls occurred along the coast as well, producing blocks of up to 40 tons that are now found inland. This is also consistent with the identification of a possible tsunami deposit in Mejillones Bay that has been dated to the range 1409 to 1449. Deposits found by coring of recent sediments in wetland near Tongoy Bay have also been linked to the 1420 tsunami.

Patriarchal State Of Friuli
The Patria del Friuli ( la, Patria Fori Iulii, fur, Patrie dal Friûl) was the territory under the temporal rule of the Patriarch of Aquileia and one of the ecclesiastical states of the Holy Roman Empire. In 1420, the Republic of Venice acquired it, but it continued to be ruled for some time under its own laws and customs. Foundation The former Duchy of Friuli in the Italian Kingdom of the Lombards had been conquered by Charlemagne in 774 and incorporated as a march of the Carolingian Empire. When in 952 King Otto I of Germany invaded Italy, he added the Friulian territory to the March of Verona, ruled by the Dukes of Bavaria, from 976 by the Dukes of Carinthia. During the Investiture Controversy of 1077, King Henry IV of Germany deposed the Veronese margrave Duke Berthold II of Carinthia, as he had sided with antiking Rudolf of Rheinfelden. On 3 April 1077 at Pavia Henry, on his way back from the Walk to Canossa, vested Patriarch Sieghard of Beilstein with immediate com ...

Catherine Of Valois
Catherine of Valois or Catherine of France (27 October 1401 – 3 January 1437) was Queen of England from 1420 until 1422. A daughter of Charles VI of France, she was married to Henry V of England and gave birth to his heir Henry VI of England. Catherine's marriage was part of a plan to eventually place Henry V on the throne of France, and perhaps end what is now known as the Hundred Years' War, but although her son Henry VI was later crowned in Paris, this ultimately failed. After Henry V's death, Catherine's later marriage with Owen Tudor proved the springboard of the Tudor family's fortunes, eventually leading to their grandson's elevation as Henry VII of England. Catherine's older sister Isabella was also a Queen of England as the child bride of Richard II. Early life Catherine of Valois was the youngest daughter of King Charles VI of France and his wife Isabeau of Bavaria. She was born at the Hôtel Saint-Pol (a royal palace in Paris) on 27 October 1401. Early on, t ...

Filippo Brunelleschi
Filippo Brunelleschi ( , , also known as Pippo; 1377 – 15 April 1446), considered to be a founding father of Renaissance architecture, was an Italian architect, designer, and sculptor, and is now recognized to be the first modern engineer, planner, and sole construction supervisor. In 1421, Brunelleschi became the first person to receive a patent in the Western world. He is most famous for designing the dome of the Florence Cathedral, a feat of engineering that had not been accomplished since antiquity, as well as the development of the mathematical technique of linear perspective in art which governed pictorial depictions of space until the late 19th century and influenced the rise of modern science. His accomplishments also include other architectural works, sculpture, mathematics, engineering, and ship design. His principal surviving works can be found in Florence. Biography Early life Brunelleschi was born in Florence, Italy, in 1377. His family consisted of his father, ...

Çelebi Sultan Mehmed Mosque
The Çelebi Sultan Mehmed Mosque ( tr, Çelebi Sultan Mehmed Camii; el, Τέμενος Μεχμέτ Α'), also known as the Bayezid Mosque (Τέμενος Βαγιαζήτ) and the Great Mosque ( tr, Büyük Camii or ''Ulu Camii''), is an early 15th-century Ottoman Empire, Ottoman mosque in Didymoteicho, East Macedonia and Thrace, in the far northeast of Greece. Construction The 17th-century Ottoman traveller Evliya Çelebi records that the mosque was begun under Sultan Bayezid I (r. 1389–1402), but after his death at the Battle of Ankara and the turmoil that followed, it was interrupted. Construction was taken up again under Sultan Mehmed I (r. 1413–1421), and the mosque was completed and inaugurated in March 1420, as recorded in the inscription above the main entrance. A second inscription over a side-entrance records the name of the architect Ivaz ibn Bayezid, the builder (donor) Dogan ibn Abdullah and the local ''qadi'', Seyid Ali, who supervised construction.

Henry The Navigator
''Dom'' Henrique of Portugal, Duke of Viseu (4 March 1394 – 13 November 1460), better known as Prince Henry the Navigator ( pt, Infante Dom Henrique, o Navegador), was a central figure in the early days of the Portuguese Empire and in the 15th-century European maritime discoveries and maritime expansion. Through his administrative direction, he is regarded as the main initiator of what would be known as the Age of Discovery. Henry was the fourth child of the Portuguese King John I, who founded the House of Aviz. After procuring the new caravel ship, Henry was responsible for the early development of Portuguese exploration and maritime trade with other continents through the systematic exploration of Western Africa, the islands of the Atlantic Ocean, and the search for new routes. He encouraged his father to conquer Ceuta (1415), the Muslim port on the North African coast across the Straits of Gibraltar from the Iberian Peninsula. He learned of the opportunities offered by th ...

Ghiyāth Al-dīn Naqqāsh
Mawlānā Ghiyāth al-dīn Naqqāsh (غیاث الدین نقاش) ( fl. 1419-22) was an envoy of the Timurid ruler of Persia and Transoxania, Mirza Shahrukh (r. 1404–1447), to the court of the Yongle Emperor (r. 1402–1424) of the Ming Dynasty of China, known for an important account he wrote of his embassy. His name has also been transcribed in English works as Ḡīāṯ-al-Dīn Naqqaš, Ghiyasu'd-Din Naqqash, Ghiyāthu'd-Dīn Naqqāsh, or Ghiyathuddin Naqqash. Ghiyasu'd-Din Naqqash was the official diarist of the large embassy sent by Mirza Shahrukh, whose capital was in Herat, to the court of China's Yongle Emperor in 1419. According to Vasily Bartold, he was a painter, as the moniker "Naqqash" indicated. Nothing is known of Ghiyasu'd-Din Naqqash beyond what he tells in his diary. Rosemarie Quiring-Zoche suggested in 1980 that he may have been the same person as Mawlānā Ghiyāthu'd-Dīn Simnānī known from other sources, but later authors have viewed this ...
