Roman Calendar
The Roman calendar was the calendar used by the Roman Kingdom and Roman Republic. The term often includes the Julian calendar established by the reforms of the Roman dictator, dictator Julius Caesar and Roman emperor, emperor Augustus in the late 1stcenturyBC and sometimes includes any system dated by inclusive counting towards months' kalends, nones (calendar), nones, and ides (calendar), ides in the Roman manner. The term usually excludes the Alexandrian calendar of Roman Egypt, which continued the unique months of that land's Egyptian calendar, former calendar; the Byzantine calendar of the Byzantine Empire, later Roman Empire, which usually dated the Roman months in the simple count of the ancient Greek calendars; and the Gregorian calendar, which refined the Julian system to bring it into still closer alignment with the tropical year. Roman dates were counted inclusively forward to the next of three principal days: the first of the month (the kalends), a day shortly befor ...

Roman Empire
The Roman Empire ( la, Imperium Romanum ; grc-gre, Βασιλεία τῶν Ῥωμαίων, Basileía tôn Rhōmaíōn) was the post-Republican period of ancient Rome. As a polity, it included large territorial holdings around the Mediterranean Sea in Europe, North Africa, and Western Asia, and was ruled by emperors. From the accession of Caesar Augustus as the first Roman emperor to the military anarchy of the 3rd century, it was a Principate with Italia as the metropole of its provinces and the city of Rome as its sole capital. The Empire was later ruled by multiple emperors who shared control over the Western Roman Empire and the Eastern Roman Empire. The city of Rome remained the nominal capital of both parts until AD 476 when the imperial insignia were sent to Constantinople following the capture of the Western capital of Ravenna by the Germanic barbarians. The adoption of Christianity as the state church of the Roman Empire in AD 380 and the fall of the Western ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ab Urbe Condita
''Ab urbe condita'' ( 'from the founding of the City'), or ''anno urbis conditae'' (; 'in the year since the city's founding'), abbreviated as AUC or AVC, expresses a date in years since 753 BC, the traditional founding of Rome. It is an expression used in antiquity and by classical historians to refer to a given year in Ancient Rome. In reference to the traditional year of the foundation of Rome, the year 1 BC would be written AUC 753, whereas AD 1 would be AUC 754. The foundation of the Roman Empire in 27 BC would be AUC 727. Usage of the term was more common during the Renaissance, when editors sometimes added AUC to Roman manuscripts they published, giving the false impression that the convention was commonly used in antiquity. In reality, the dominant method of identifying years in Roman times was to name the two consuls who held office that year. In late antiquity, regnal years were also in use, as in Roman Egypt during the Diocletian era after AD 293, and in the B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anno Domini
The terms (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term is Medieval Latin and means 'in the year of the Lord', but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "''anno Domini nostri Jesu Christi''", which translates to 'in the year of our Lord Jesus Christ'. The form "BC" is specific to English and equivalent abbreviations are used in other languages: the Latin form is but is rarely seen. This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus, ''AD'' counting years from the start of this epoch and ''BC'' denoting years before the start of the era. There is no year zero in this scheme; thus ''the year AD 1 immediately follows the year 1 BC''. This dating system was devised in 525 by Dionysius Exiguus, but was not widely used until the 9th century. Traditionally, English follows Latin usage by placing the "AD" abbr ...

Calendar Era
A calendar era is the period of time elapsed since one ''epoch'' of a calendar and, if it exists, before the next one. For example, it is the year as per the Gregorian calendar, which numbers its years in the Western Christian era (the Coptic Orthodox and Ethiopian Orthodox churches have their own Christian eras). In antiquity, regnal years were counted from the accession of a monarch. This makes the chronology of the ancient Near East very difficult to reconstruct, based on disparate and scattered king lists, such as the Sumerian King List and the Babylonian Canon of Kings. In East Asia, reckoning by era names chosen by ruling monarchs ceased in the 20th century except for Japan, where they are still used. Ancient dating systems Assyrian eponyms For over a thousand years, ancient Assyria used a system of eponyms to identify each year. Each year at the Akitu festival (celebrating the Mesopotamian new year), one of a small group of high officials (including the king in lat ...

Sun Tzu
Sun Tzu ( ; zh, t=孫子, s=孙子, first= t, p=Sūnzǐ) was a Chinese military general, strategist, philosopher, and writer who lived during the Eastern Zhou period of 771 to 256 BCE. Sun Tzu is traditionally credited as the author of ''The Art of War'', an influential work of military strategy that has affected both Western and East Asian philosophy and military thinking. Sun Tzu is revered in Chinese and East Asian culture as a legendary historical and military figure. His birth name was Sun Wu ( zh, t=孫武, s=孙武, first=t) and he was known outside of his family by his courtesy name Changqing ( zh, t=長卿). The name ''Sun Tzu'' by which he is more popularly known is an honorific which means "Master Sun". Sun Tzu's historicity is uncertain. The Han dynasty historian Sima Qian and other traditional Chinese historians placed him as a minister to King Helü of Wu and dated his lifetime to 544–496 BCE. Modern scholars accepting his historicity place the extant text of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Art Of War
''The Art of War'' () is an ancient Chinese military treatise dating from the Late Spring and Autumn Period (roughly 5th century BC). The work, which is attributed to the ancient Chinese military strategist Sun Tzu ("Master Sun"), is composed of 13 chapters. Each one is devoted to a different set of skills or art related to warfare and how it applies to military strategy and tactics. For almost 1,500 years it was the lead text in an anthology that was formalized as the Seven Military Classics by Emperor Shenzong of Song in 1080. ''The Art of War'' remains the most influential strategy text in East Asian warfare and has influenced both Far Eastern and Western military thinking, business tactics, legal strategy, politics, sports, lifestyles and beyond. The book contains a detailed explanation and analysis of the 5th-century BC Chinese military, from weapons, environmental conditions, and strategy to rank and discipline. Sun also stressed the importance of intelligence ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wu (state)
Wu (; Old Chinese: ''*'') was one of the states during the Western Zhou dynasty and the Spring and Autumn period. It was also known as Gouwu ( /''*''/) or Gongwu ( /''*''/) from the pronunciation of the local language. Wu was located at the mouth of the Yangtze River east of the State of Chu. Its first capital was at Meili (probably in modern Wuxi) and was later moved to Gusu (姑蘇, modern Suzhou) and then Helu City (the old town of present-day Suzhou). History A founding myth of Wu, first recorded by Sima Qian in the Han dynasty, traced its royal lineage to Taibo, a relative of King Wen of Zhou. According to the ''Records of the Grand Historian'', Taibo was the oldest son of Gugong Danfu and the elder uncle of King Wen who started the Zhou Dynasty. Gugong Danfu had three sons named Taibo, Zhongyong, and Jili. Taibo was the oldest of three brothers, Jili being the youngest. Realizing that his youngest brother, Jili, was favored by his father to inherit the throne of Pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Strategy
Military strategy is a set of ideas implemented by military organizations to pursue desired strategic goals. Derived from the Greek word '' strategos'', the term strategy, when it appeared in use during the 18th century, was seen in its narrow sense as the "art of the general", or "'the art of arrangement" of troops. Military strategy deals with the planning and conduct of campaigns, the movement and disposition of forces, and the deception of the enemy. The father of Western modern strategic studies, Carl von Clausewitz (1780–1831), defined military strategy as "the employment of battles to gain the end of war." B. H. Liddell Hart's definition put less emphasis on battles, defining strategy as "the art of distributing and applying military means to fulfill the ends of policy". Hence, both gave the pre-eminence to political aims over military goals. Sun Tzu (544–496 BC) is often considered as the father of Eastern military strategy and greatly influenced Chinese, Japanese ...

Xu (state)
The State of Xu () (also called Xu Rong () or Xu Yi () by its enemies) was an independent Huaiyi state of the Chinese Bronze Age that was ruled by the Ying family () and controlled much of the Huai River valley for at least two centuries. It was centered in northern Jiangsu and Anhui. An ancient but originally minor state that already existed during the late Shang dynasty, Xu was subjugated by the Western Zhou dynasty around 1039 BC, and was gradually sinified from then on. It eventually regained its independence and formed a confederation of 36 states that became powerful enough to challenge the Zhou empire for supremacy over the Central Plain. Able to consolidate its rule over a territory that stretched from Hubei in the south, through eastern Henan, northern Anhui and Jiangsu, as far north as southern Shandong, Xu's confederation remained a major power until the early Spring and Autumn period. It reached its apogee in the mid 8th century BC, expanding its influence as far a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
