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 common year starting on Monday is any non-leap year that begins on Monday, 1 January, and ends on Monday, 31 December. Its dominical letter hence is G. The most recent year of such kind was 2018 and the next one will be 2029 in the Gregorian calendar, or likewise, 2013 and 2019 in the obsolete Julian calendar. The century year, 1900, was also a common year starting on Monday in the Gregorian calendar. See below for more. Any common year that starts on Sunday, Monday or Tuesday has two Friday the 13ths. This common year of this type contains two Friday the 13ths in April and July. Leap years starting on Sunday share this characteristic, but also have another in January.

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.




The Treaty of Gallipoli, concluded in January or early February 1403, was a peace treaty between Süleyman Çelebi, ruler of the Ottoman territories in the Balkans, and the main Christian regional powers: the Byzantine Empire, the Republic of Venice, the Republic of Genoa, the Knights Hospitaller, and the Duchy of Naxos. Concluded in the aftermath of the Battle of Ankara, while Süleyman tried to strengthen his own position in the succession struggle with his brothers, the treaty brought major concessions to the Christian states, especially the Byzantines, who regained lost territories and achieved a position of nominal superiority over the Ottoman ruler. Its provisions were honoured by Süleyman as well as by Mehmed I, the victor of the Ottoman succession struggle, but collapsed after Mehmed's death in 1421.

Süleyman Çelebi Ottoman prince

Süleyman Çelebi was an Ottoman prince and a co-ruler of the empire for several years during the Ottoman Interregnum. The name Çelebi is an honorific title meaning gentleman; see pre-1934 Turkish naming conventions.

Byzantine Empire Roman Empire during Late Antiquity and the Middle Ages

The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, and military force in Europe. Both the terms "Byzantine Empire" and "Eastern Roman Empire" are historiographical terms created after the end of the realm; its citizens continued to refer to their empire simply as the Roman Empire, or Romania (Ῥωμανία), and to themselves as "Romans".
