993–994 Carbon-14 Spike
The 993–994 carbon-14 spike was a rapid 0.91% increase in carbon-14 isotope content from tree rings dated 993–994 CE. This event was also confirmed with an associated increase of beryllium-10 in Antarctic ice core samples, supporting the hypothesis that this event was of solar origin. There were several astronomical observations during this time that correspond with the and spikes, but these texts are few and far between. In 2021, a scientific paper used the 993–994 carbon-14 spike as a benchmark in dendrochronology (tree-ring studies) to precisely determine that Vikings were present in L'Anse aux Meadows in Newfoundland exactly 1000 years prior, in 1021 AD. Historical observations The solar storm hypothesis is heavily supported by several observations of aurora events from late 992 in Korea, Germany and Ireland, usually describing a red sky, presumably because of major auroras. The historical observations do not completely prove the cause of the 993–994 spike but sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Ibn Naghrillah
Shmuel ibn Naghrillah (; ), mainly known as Shmuel HaNagid () and Isma'il ibn Naghrilla (993–1056), was a Jewish statesman, military commander, scholar, linguist and poet in medieval al-Andalus. He served as grand vizier of the Taifa of Granada, commander of its army in battle, and leader of the local Jewish community. Rising to unprecedented prominence in both Muslim and Jewish spheres, he became one of the most powerful and influential Jews in medieval Spain. Stillman, Norman A.

Earth
Earth is the third planet from the Sun and the only astronomical object known to Planetary habitability, harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering Water distribution on Earth, 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is at least somewhat humid and covered by vegetation, while large Ice sheet, sheets of ice at Polar regions of Earth, Earth's polar polar desert, deserts retain more water than Earth's groundwater, lakes, rivers, and Water vapor#In Earth's atmosphere, atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's outer core, Earth has a liquid outer core that generates a ...

Dendrochronology
Dendrochronology (or tree-ring dating) is the scientific method of chronological dating, dating tree rings (also called growth rings) to the exact year they were formed in a tree. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from the wood of old trees. Dendrochronology derives from the Ancient Greek (), meaning "tree", (), meaning "time", and (), "the study of". Dendrochronology is useful for determining the precise age of samples, especially those that are too recent for radiocarbon dating, which always produces a range rather than an exact date. However, for a precise date of the death of the tree a full sample to the edge is needed, which most trimmed timber will not provide. It also gives data on the timing of events and rates of change in the environment (most prominently climate) and also in wood found in archaeology or works of art and architecture, such as old pane ...

Otto III
Otto III (June/July 980 – 23 January 1002) was the Holy Roman emperor and King of Italy from 996 until his death in 1002. A member of the Ottonian dynasty, Otto III was the only son of Emperor Otto II and his wife Theophanu. Otto III was crowned as king of Germany in 983 at the age of three, shortly after his father's death in Southern Italy while campaigning against the Byzantine Empire and the Emirate of Sicily. Though the nominal ruler of Germany, Otto III's minor status ensured his various regents held power over the Empire. His cousin Duke Henry II of Bavaria, initially claimed regency over the young king and attempted to seize the throne for himself in 984. When his rebellion failed to gain the support of Germany's aristocracy, Henry II was forced to abandon his claims to the throne and to allow Otto III's mother Theophanu to serve as regent until her death in 991. Otto III was then still a child, so his grandmother, Adelaide of Italy, served as regent until 994. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto, Duke Of Lower Lorraine
Otto (c. 970–1012) was the duke of Lower Lorraine in the Kingdom Germany from 993 until his death. He was the son of Charles, son of King Louis IV of France, and his first wife, Adelaide of Troyes. When his father left the duchy to fight Hugh Capet for the throne of France in 987, he became regent in Lower Lorraine when still apparently under twenty. Charles was defeated definitively in 991 and died two years later a prisoner in Orléans. Otto then succeeded into the full dukedom. In 1002, at the death of the Holy Roman Emperor Otto III, he was one of the loyal nobles who accompanied his body from Paterno to Aachen Aachen is the List of cities in North Rhine-Westphalia by population, 13th-largest city in North Rhine-Westphalia and the List of cities in Germany by population, 27th-largest city of Germany, with around 261,000 inhabitants.

Majd Al-Dawla
Abu Talib Rustam (; 997–1029), commonly known by his ''laqab'' (honorific title) of Majd al-Dawla (), was the last ''amir'' (ruler) of the Buyid amirate of Ray from 997 to 1029. He was the eldest son of Fakhr al-Dawla (). A weak ruler, he was a figurehead most of his reign, whilst his mother Sayyida Shirin was the real ruler of the kingdom. Majd al-Dawla's reign saw the gradual shrinking of Buyid holdings in central Iran; Gurgan and Tabaristan had been lost to the Ziyarids in 997, while several of the western towns were seized by the Sallarids of Azerbaijan. There were also internal troubles, such as the revolt of the Daylamite military officer Ibn Fuladh in 1016. Following the death of Sayyida Shirin in 1028, Majd al-Dawla was faced with a revolt by his Daylamite soldiers, and thus requested the assistance of the Ghaznavid ruler Mahmud () in dealing with them. Mahmud came to Ray in 1029, deposed Majd al-Dawla as ruler, and sacked the city, bringing an end to Buyid rul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulrich Of Augsburg
Ulrich of Augsburg (890 – 4 July 973), sometimes spelled ''Uodalric'' or ''Odalrici'', was Prince-Bishop of Augsburg in the Holy Roman Empire. He was the first saint to be canonised not by a local authority but by a Pope. Life Early years Much of the information concerning Ulrich is derived from the ''Life of St Ulrich'' written by Gerhard of Augsburg sometime between 982 and 993. Ulrich was born in 890 at Kyburg in present-day canton of Zürich in Switzerland. He was the son of Hupald, Count of Dillingen (d. 909) and Dietpirch of Swabia (also known as Theoberga).Schmid, Ulrich, "St. Ulrich", Catholic Encyclopedia Vol. 15, New York, Robert Appleton Company, 1912, 25 January 2014.

Ice Core
An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires .... Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper ones, and an ice core contains ice formed over a range of years. Cores are Ice drilling, drilled with hand Auger (drill), augers (for shallow holes) or powered drills; they can reach depths of over two miles (3.2 km), and contain ice up to 800,000 years old. The physical properties of the ice and of material trapped in it can be used to reconstruct the climate over the age range of the core. The proportions of different oxygen and hydrogen isotopes provide information about Paleothermometer, ancient temperatures, a ...

Charles, Duke Of Lower Lorraine
Charles (c. 953 – 22 June 992/995?) was the duke of Lower Lorraine from 977 until his death. Life Born at Reims in the summer of 953, Charles was the son of Louis IV of France and Gerberga of Saxony and the younger brother of King Lothair.
