A regnal year is a year of the reign of a sovereign, from the Latin regnum meaning kingdom, rule.

The oldest dating systems were in regnal years, and considered the date as an ordinal, not a cardinal number. For example, a monarch could have a first year of rule, a second year of rule, a third, and so on, but a zero year of rule would be nonsense. Applying this ancient epoch system to modern calculations of time, which include zero, is what led to the debate over when the third millennium began.

In ancient times, calendars were counted in terms of the number of years of the reign of the current monarch. Reckoning long periods of times required a king list. The oldest such reckoning is preserved in the Sumerian king list.

In England, and later the United Kingdom, until 1963, each Act of Parliament was defined by its serial number within the session of parliament in which it was enacted, which in turn was denoted by the regnal year or years in which it fell. (See Regnal years of English monarchs)

Saint George (c. 275/281 – 23 April 303) was, according to tradition, a Roman soldier from Syria Palaestina and a soldier in the Guard of Diocletian, who is venerated as a Christian martyr. In hagiography Saint George is one of the most venerated saints in the Catholic (Western and Eastern Rites), Anglican, Eastern Orthodox, and the Oriental Orthodox churches. He is immortalized in the tale of Saint George and the Dragon and is one of the Fourteen Holy Helpers. His memorial is celebrated on 23 April, and he is regarded as one of the most prominent military saints.

Many Patronages of Saint George exist around the world, including: Georgia, England, Egypt, Bulgaria, Aragon, Catalonia, Romania, Ethiopia, Greece, India, Iraq, Lithuania, Palestine, Portugal, Serbia, Ukraine and Russia, as well as the cities of Genoa, Amersfoort, Beirut, Botoşani, Drobeta Turnu-Severin, Timişoara, Fakiha, Bteghrine, Cáceres, Ferrara, Freiburg, Kragujevac, Kumanovo, Ljubljana, Pérouges, Pomorie, Preston, Qormi, Rio de Janeiro, Lod, Lviv, Barcelona, Moscow, Tamworth and the Maltese island of Gozo, as well as of the Scout Movement and a wide range of professions, organizations and disease sufferers.

Ramesses II (c. 1303 BC – July or August 1213 BC; Egyptian: *Riʻmīsisu, alternatively transcribed as Rameses  /ˈræməsiːz/ and Ramses /ˈræmsiːz/ or /ˈræmziːz/), referred to as Ramesses the Great, was the third Egyptian pharaoh (reigned 1279 BC – 1213 BC) of the Nineteenth dynasty. He is often regarded as the greatest, most celebrated, and most powerful pharaoh of the Egyptian Empire. His successors and later Egyptians called him the "Great Ancestor." Ramesses II led several military expeditions into the Levant, re-asserting Egyptian control over Canaan. He also led expeditions to the south, into Nubia, commemorated in inscriptions at Beit el-Wali and Gerf Hussein.

At age fourteen, Ramesses was appointed Prince Regent by his father Seti I. He is believed to have taken the throne in his late teens and is known to have ruled Egypt from 1279 BC to 1213 BC for 66 years and 2 months, according to both Manetho and Egypt's contemporary historical records. He was once said to have lived to be 99 years old, but it is more likely that he died in his 90th or 91st year. If he became Pharaoh in 1279 BC as most Egyptologists today believe, he would have assumed the throne on May 31, 1279 BC, based on his known accession date of III Shemu day 27. Ramesses II celebrated an unprecedented 14 sed festivals (the first held after thirty years of a pharaoh's reign, and then every three years) during his reign—more than any other pharaoh. On his death, he was buried in a tomb in the Valley of the Kings; his body was later moved to a royal cache where it was discovered in 1881, and is now on display in the Cairo Museum.

Muwatalli II (^mNIR.GÁL) (also Muwatallis, or Muwatallish) was a king of the New kingdom of the Hittite empire (ca. 1295–1272 BC (short chronology)).

He was the eldest son of Mursili II and Queen Gassulawiya, and he had several siblings.

He is best known as the Hittite ruler who fought Ramesses II to a standstill at the Battle of Kadesh around 1274 BC. Aside from the battle with Egypt, he is best known for relocating the Hittite capital to Tarhuntassa and appointing his brother Hattusili as governor in Hattusa.

A copy of a treaty has been recovered between him and Alaksandu, ruler of Wilusa (Troy), one of the Arzawa lands.

Egyptologists^{[citation needed]} suspect that some time prior to Ramesses II's accession to the Egyptian throne, Muwattalli had reached an informal peace treaty or understanding with Seti I over Kadesh to avoid a clash between the two superpowers over control of Syria. In it, Seti effectively ceded Kadesh to the Hittite king in order to focus on domestic issues in Egypt.

Muwatalli had a wife named Tanu-Ḫepa and at least two children. One was Urhi-Teshup, who became king Mursili III until his uncle Hattusili III deposed him. Another was Kurunta who became the vassal ruler of Tarhuntassa during the reign of Hattusili III. Another person named Ulmi-Teshup is suggested to be a third son of Muwatalli II but it is quite likely that Ulmi-Teshup and Kurunta are the same person.

Nebuchadnezzar II (ⁱ/nɛbjʉkədˈnɛzər/; Aramaic: ܢܵܒܘܼ ܟܘܼܕܘܼܪܝܼ ܐܘܼܨܘܼܪ ‎; Hebrew: נְבוּכַדְנֶצַּר‎‎ Nəḇūḵaḏneṣṣar; Ancient Greek: Ναβουχοδονόσωρ Naboukhodonósôr; Arabic: نِبُوخَذنِصَّر nibūḫaḏniṣṣar; c 634 – 562 BC) was king of the Neo-Babylonian Empire, who reigned c. 605 BC – 562 BC. According to the Bible, he conquered Judah and Jerusalem, and sent the Jews into exile. He is credited with the construction of the Hanging Gardens of Babylon and also known for the destruction of the First Temple. He is featured in the Book of Daniel and is also mentioned in several other books of the Bible. The Akkadian name, Nabû-kudurri-uṣur, means "O god Nabu, preserve/defend my firstborn son". Nabu is the Babylonian deity of wisdom, and son of the god Marduk. In an inscription, Nebuchadnezzar styles himself as Nabu's "beloved" and "favourite".

His name has previously been mistakenly interpreted as "O Nabu, defend my kudurru", in which sense a kudurru is an inscribed stone deed of property. However, when contained in a ruler's title, kudurru approximates to "firstborn son" or "oldest son". Variations of the Hebrew form include נְבוּכַדְנֶאצַּר and נְבוּכַדְרֶאצַּר (Nəḇuḵaḏreṣṣar). He is also known as Bakhat Nasar, which means "winner of the fate", or literally, "fate winner".^{[citation needed]}
