Roman numerals Numbers in the Roman numeral system

The numeric system represented by Roman numerals 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. Roman numerals, as used today, employ seven symbols, each with a fixed integer value, as follows:

A leap year starting on Monday is any year with 366 days that begins on Monday, 1 January, and ends on Tuesday, 31 December. Its dominical letters hence are GF, such as the years 1912, 1940, 1968, 1996, 2024, 2052, 2080, and 2120 in the Gregorian calendar or, likewise, 2008, 2036, and 2064 in the obsolete Julian calendar. Any leap year that starts on Monday, Wednesday or Thursday has two Friday the 13ths. This leap year contains two Friday the 13ths in September and December. Common years starting on Tuesday share this characteristic.

The Julian calendar, proposed by Julius Caesar in 46 BC, was a reform of the Roman calendar. It took effect on 1 January 45 BC, 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 refined and gradually replaced by the Gregorian calendar, promulgated in 1582 by Pope Gregory XIII.

<i>Reconquista</i> period in the history of the Iberian Peninsula

The Reconquista is a name used in English to describe the period in the history of the Iberian Peninsula of about 780 years between the Umayyad conquest of Hispania in 711 and the fall of the Nasrid kingdom of Granada to the expanding Christian kingdoms in 1491.

Wu Zhen (painter) 14th-century Chinese painter

Wu Zhen was a painter born in Jiaxing, Zhejiang Province, during the Yuan dynasty of China, one of the so-called Four Masters of the Yuan Dynasty. He followed the Dong Yuan school of painting. Following along with trends of the time, Wu's works tended less toward naturalism and more toward abstraction, focusing on dynamic balance of elements, and personifying nature. His painting The Central Mountain, dated 1336, is perhaps his greatest work and shows his style very clearly. It is a symmetrical image, with one large mountain in its center and others to each side. The mountains have rounded tops, and in fact all of Wu's lines in this painting are smooth, curved and flowing. The painting is a reinterpretation of traditional landscape paintings as it brings abstract style and brushwork to landscape, primarily to create a work focused on balance.

Boniface of Savoy (bishop) 13th-century Archbishop of Canterbury and saint

Boniface of Savoy was a medieval Bishop of Belley in France and Archbishop of Canterbury in England. He was the son of Thomas, Count of Savoy, and owed his initial ecclesiastical posts to his father. Other members of his family were also clergymen, and a brother succeeded his father as count. One niece was married to King Henry III of England and another was married to King Louis IX of France. It was Henry who secured Boniface's election as Archbishop, and throughout his tenure of that office he spent much time on the continent. He clashed with his bishops, with his nephew-by-marriage, and with the papacy, but managed to eliminate the archiepiscopal debt which he had inherited on taking office. During Simon de Montfort's struggle with King Henry, Boniface initially helped Montfort's cause, but later supported the king. After his death in Savoy, his tomb became the object of a cult, and he was eventually beatified in 1839.

Bulgarian Empire Midieval empire in SouthEastern Europe

In the medieval history of Europe, Bulgaria's status as the Bulgarian Empire, wherein it acted as a key regional power occurred in two distinct periods: between the seventh and eleventh centuries, and again between the twelfth and fourteenth centuries. The two "Bulgarian Empires" are not treated as separate entities, but rather as one state restored after a period of Byzantine rule over its territory. Bulgaria is one of the few historic states and nations whose economy and society were never based on slavery, and slavery never played an important role in Bulgarian statehood development and wealth.
