Roman numerals Numbers in the Roman numeral system

Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers in this system are represented by combinations of letters from the Latin alphabet. Modern usage employs seven symbols, each with a fixed integer value:

A common year starting on Thursday is any non-leap year that begins on Thursday, 1 January, and ends on Thursday, 31 December. Its dominical letter hence is D. The most recent year of such kind was 2015 and the next one will be 2026 in the Gregorian calendar or, likewise, 2010 and 2021 in the obsolete Julian calendar, see below for more. This common year contains the most Friday the 13ths; specifically, the months of February, March, and November. Leap years starting on Sunday share this characteristic. From February until March in this type of year is also the shortest period that occurs within a Friday the 13th.

The Julian calendar, proposed by Julius Caesar in 708 AUC (46 BC/BCE), was a reform of the Roman calendar. It took effect on 1 January 709 AUC (45 BC/BCE), by edict. It was the predominant calendar in the Roman world, most of Europe, and in European settlements in the Americas and elsewhere, until it was gradually replaced by the Gregorian calendar, promulgated in 1582 by Pope Gregory XIII.

Jayavarman VII Cambodian king, considered by historians to be the most powerful Khmer monarch of all time

Jayavarman VII, posthumous name of Mahaparamasaugata, was a king of the Khmer Empire in present-day Siem Reap, Cambodia. He was born in circa 1122. He was the son of King Dharanindravarman II and Queen Sri Jayarajacudamani. He married Princess Jayarajadevi and then, after her death, married her sister Indradevi. The two women are commonly thought to have been a great inspiration to him, particularly in his unusual devotion to Buddhism, as only one prior Khmer king was a Buddhist. He then built the Bayon as a monument to Buddhism. Jayavarman VII is generally considered the most powerful of the Khmer monarchs by historians.

Khmer Empire Empire extending over large parts of Southeast Asia

The Khmer Empire, officially the Angkor Empire, the predecessor state to modern Cambodia, was a Hindu-Buddhist empire in Southeast Asia. The empire, which grew out of the former kingdoms of Funan and Chenla, at times ruled over and/or vassalised most of mainland Southeast Asia and parts of Southern China, stretching from the tip of the Indochinese Peninsula northward to modern Yunnan province, China, and from Vietnam westward to Myanmar.

  • Chinese and Japanese astronomers observe what has since come to be understood as supernova SN 1181. One of only eight supernovae in the Milky Way observed in recorded history, it appears in the constellation Cassiopeia, and is visible in the night sky for about 185 days. The radio source 3C58 is thought to be the remnant from this event.

Supernova Star exploding at the end of its stellar evolution

A supernova is a powerful and luminous stellar explosion. A supernova is a transient astronomical event, occurring during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion. The original star, called the progenitor, either collapses to a neutron star or black hole, or it is completely destroyed. The peak optical luminosity of a supernova can be comparable to that of an entire galaxy, before fading over several weeks or months.

SN 1181 supernova within Cassiopeia, observed in 1181

First observed between August 4 and August 6, 1181, Chinese and Japanese astronomers recorded the supernova now known as SN 1181 in eight separate texts. One of only eight supernovae in the Milky Way observable with the naked eye in recorded history, it appeared in the constellation Cassiopeia and was visible in the night sky for about 185 days.

Milky Way Spiral galaxy containing our Solar System

The Milky Way is the galaxy that contains the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term Milky Way is a translation of the Latin via lactea, from the Greek γαλαξίας κύκλος. From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from its outer rim. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies.

Béla III of Hungary King of Hungary

Béla III was King of Hungary and Croatia between 1172 and 1196. He was the second son of King Géza II and Géza's wife, Euphrosyne of Kiev. Around 1161, Euphrosyne granted Béla a duchy, which included Croatia, central Dalmatia and possibly Sirmium. In accordance with a peace treaty between his elder brother, Stephen III, who succeeded their father in 1162, and the Byzantine Emperor Manuel I Komnenos, Béla moved to Constantinople in 1163. He was renamed to Alexios, and the emperor granted him the newly created senior court title of despotes. He was betrothed to the Emperor's daughter, Maria. Béla's patrimony caused armed conflicts between the Byzantine Empire and the Kingdom of Hungary between 1164 and 1167, because Stephen III attempted to hinder the Byzantines from taking control of Croatia, Dalmatia and Sirmium. Béla-Alexios, who was designated as Emperor Manuel's heir in 1165, took part in three Byzantine campaigns against Hungary. His betrothal to the emperor's daughter was dissolved after her brother, Alexios, was born in 1169. The emperor deprived Béla of his high title, granting him the inferior rank of kaisar.

During the first four years of his reign, he fought his rebellious brother, Andrew, who forced Emeric to make him ruler of Croatia and Dalmatia as appanage.
