States Of Germany
The Federal Republic of Germany is a federation and consists of sixteen partly sovereign ''states''. Of the sixteen states, thirteen are so-called area-states ('Flächenländer'); in these, below the level of the state government, there is a division into local authorities (counties and county-level cities) that have their own administration. Two states, Berlin and Hamburg, are city-states, in which there is no separation between state government and local administration. The state of Bremen (state), Bremen is a special case: the state consists of the cities of Bremen (city), Bremen, for which the state government also serves as the municipal administration, and Bremerhaven, which has its own local administration separate from the state government. It is therefore a mixture of a city-state and an area-state. Three states, Bavaria, Saxony, and Thuringia, use the appellation ("free state"); this title is merely stylistic and carries no legal or political significance (similar t ...

Archaeology
Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, archaeological site, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. The discipline involves Survey (archaeology), surveying, Archaeological excavation, excavation, and eventually Post excavation, analysis of data collected, to learn more about the past. In broad scope, archaeology relies on cross-disciplinary research. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. A ...

County Of Mark
The County of Mark (, colloquially known as ) was a county and Imperial State, state of the Holy Roman Empire in the Lower Rhenish–Westphalian Circle. It lay south of Lippe (river), Lippe river on both sides of the Ruhr river along the Volme and Lenne rivers. The Counts de la Mark were among the most powerful and influential Westphalian lords in the Holy Roman Empire. The name ''Mark'' derived from a small village Mark and the nearby Castle Mark, the latter was built between 1190 and 1202, both today incorporated in the unitary authority Hamm, North Rhine-Westphalia, Hamm, founded in 1226 by the first Count, Adolph de la Mark. His father used the older title Altena or Berg-Altena. The name of the county is recalled to the present-day district in lands south of the Ruhr in North Rhine-Westphalia, Germany, in 1975 when the districts were rearranged and the former district Altena was merged with former parts of neighbouring districts. The district Märkischer Kreis is only the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charlemagne
Charlemagne ( ; 2 April 748 – 28 January 814) was List of Frankish kings, King of the Franks from 768, List of kings of the Lombards, King of the Lombards from 774, and Holy Roman Emperor, Emperor of what is now known as the Carolingian Empire from 800, holding these titles until his death in 814. He united most of Western Europe, Western and Central Europe, and was the first recognised emperor to rule from the west after the fall of the Western Roman Empire approximately three centuries earlier. Charlemagne's reign was marked by political and social changes that had lasting influence on Europe throughout the Middle Ages. A member of the Frankish Carolingian dynasty, Charlemagne was the eldest son of Pepin the Short and Bertrada of Laon. With his brother, Carloman I, he became king of the Franks in 768 following Pepin's death and became the sole ruler three years later. Charlemagne continued his father's policy of protecting the papacy and became its chief defender, remo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annales Laureshamenses
The ''Annales laureshamenses'', also called ''Annals of Lorsch'' (AL), are a set of '' Reichsannalen'' (annals of the Frankish empire) that cover the years from 703 to 803, with a brief prologue. The annals begin where the "Chronica minora" of the Anglo-Saxon historian Bede leaves off—in the fifth year of the Emperor Tiberios III—and may have originally been composed as a continuation of Bede. The annals for the years up to 785 were written at the Abbey of Lorsch (whence the name), but are dependent on earlier sources. Those for the years from 785 onward form an independent source and provide especially important coverage of the imperial coronation of Charlemagne in 800. The ''Annales laureshamenses'' have been translated into English. Manuscript history An eight-leaf copy of the Lorsch annals for 703–803 was produced probably in 835 by a single scribe. Rosamond McKitterick (2004), ''History and Memory in the Carolingian World'' (Cambridge: Cambridge University Press), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mesozoic
The Mesozoic Era is the Era (geology), era of Earth's Geologic time scale, geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Period (geology), Periods. It is characterized by the dominance of archosaurian reptiles such as the dinosaurs, and of Gymnosperm, gymnosperms such as cycads, ginkgoaceae and Araucariaceae, araucarian conifers; a hot Greenhouse and icehouse earth, greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since Cambrian explosion, complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, Pterosaur, pterosaurs, Mosasaur, mosasaurs, and Plesiosaur, plesiosaurs. The Mesozoic was a time of significant tectonic, climatic, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleozoic
The Paleozoic ( , , ; or Palaeozoic) Era is the first of three Era (geology), geological eras of the Phanerozoic Eon. Beginning 538.8 million years ago (Ma), it succeeds the Neoproterozoic (the last era of the Proterozoic Eon) and ends 251.9 Ma at the start of the Mesozoic Era. The Paleozoic is subdivided into six period (geology), geologic periods (from oldest to youngest), Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian. Some geological timescales divide the Paleozoic informally into early and late sub-eras: the Early Paleozoic consisting of the Cambrian, Ordovician and Silurian; the Late Paleozoic consisting of the Devonian, Carboniferous and Permian. The name ''Paleozoic'' was first used by Adam Sedgwick (1785–1873) in 1838 to describe the Cambrian and Ordovician periods. It was redefined by John Phillips (geologist), John Phillips (1800–1874) in 1840 to cover the Cambrian to Permian periods. It is derived from the Ancient Greek, Greek ''palaiós'' (πΠ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Solutional Cave
A solutional cave, solution cave, or karst cave is a cave usually formed in a soluble rock like limestone (Calcium carbonate, with chemical formula ''CaCO3''). It is the most frequently occurring type of cave. It can also form in other rocks, including chalk, Dolomite (rock), dolomite, marble, Evaporite, salt beds, and gypsum. Process Bedrock is dissolved by carbonic acid in rainwater, groundwater, or Humic substance, humic acids from decaying vegetation, that seeps through Bed (geology), bedding planes, Geological fault, faults, Joint (geology), joints, and the like. Over time, the surface terrain breaks up into Limestone pavement, clints separated by grikes and punctuated by Sinkhole, sinkholes into which streams may disappear, crevices expand as the walls are dissolved to become caves or cave system. These may turn into large caverns or ''dolines'' when the roof collapses. The portions of a solutional cave that are below the water table or the local level of the groundwater a ...

Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tertiary (period)
The Tertiary ( ) is an obsolete geologic period spanning 66 million to 2.6 or 1.8 million years ago. The period began with the extinction of the non- avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The Tertiary has not been recognised by the International Commission on Stratigraphy (ICS) since the late 1980s, with the timespan of the Tertiary now being split in to the earlier Paleogene and the more recent Neogene periods, though the Tertiary continues to be used in some scientific publications. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied. In the early development of the study of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
