Kufrah Depression
Kufra () is a Depression (geology), basinBertarelli (1929), p. 514. and oasis group in the Kufra District of southeastern Cyrenaica in Libya. At the end of nineteenth century Kufra became the centre and holy place of the Senussi order. It also played a minor role in the Western Desert Campaign of World War II. It is located in a particularly isolated area, not only because it is in the middle of the Sahara Desert but also because it is surrounded on three sides by Depression (geology), depressions which make it dominate the passage in east-west land traffic across the desert. For the colonial Italians, it was also important as a station on the north-south air route to Italian East Africa. These factors, along with Kufra's dominance of the southeastern Cyrenaica region of Libya, highlight the strategic importance of the oasis and why it was Capture of Kufra, a point of conflict during World War II.

Cyrenaica
Cyrenaica ( ) or Kyrenaika ( ar, برقة, Barqah, grc-koi, Κυρηναϊκή παρχίαKurēnaïkḗ parkhíā}, after the city of Cyrene), is the eastern region of Libya. Cyrenaica includes all of the eastern part of Libya between longitudes E16 and E25, including the Kufra District. The coastal region, also known as '' Pentapolis'' ("Five Cities") in antiquity, was part of the Roman province of Crete and Cyrenaica, later divided into ''Libya Pentapolis'' and ''Libya Sicca''. During the Islamic period, the area came to be known as ''Barqa'', after the city of Barca. Cyrenaica became an Italian colony in 1911. After the 1934 formation of Libya, the Cyrenaica province was designated as one of the three primary provinces of the country. During World War II, it fell under British military and civil administration from 1943 until 1951, and finally in the Kingdom of Libya from 1951 until 1963. The region that used to be Cyrenaica officially until 1963 has formed seve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marl
Marl is an earthy material rich in carbonate minerals, clays, and silt. When hardened into rock, this becomes marlstone. It is formed in marine or freshwater environments, often through the activities of algae. Marl makes up the lower part of the cliffs of Dover, and the Channel Tunnel follows these marl layers between France and the United Kingdom. Marl is also a common sediment in post-glacial lakes, such as the marl ponds of the northeastern United States. Marl has been used as a soil conditioner and neutralizing agent for acid soil and in the manufacture of cement. Description Marl or marlstone is a carbonate-rich mud or mudstone which contains variable amounts of clays and silt. The term was originally loosely applied to a variety of materials, most of which occur as loose, earthy deposits consisting chiefly of an intimate mixture of clay and calcium carbonate, formed under freshwater conditions. These typically contain 35–65% clay and 65–35% carbonate. The te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Julius Maternus
The gens Julia (''gēns Iūlia'', ) was one of the most prominent patrician families in ancient Rome. Members of the gens attained the highest dignities of the state in the earliest times of the Republic. The first of the family to obtain the consulship was Gaius Julius Iulus in 489 BC. The gens is perhaps best known, however, for Gaius Julius Caesar, the dictator and grand uncle of the emperor Augustus, through whom the name was passed to the so-called Julio-Claudian dynasty of the first century AD. The Julius became very common in imperial times, as the descendants of persons enrolled as citizens under the early emperors began to make their mark in history.''Dictionary of Greek and Roman Biography and Mythology'', vol. II, pp. 642, 643. Origin The Julii were of Alban origin, mentioned as one of the leading Alban houses, which Tullus Hostilius removed to Rome upon the destruction of Alba Longa. The Julii also existed at an early period at Bovillae, evidenced by a very a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Claudius Ptolemy
Claudius Ptolemy (; grc-gre, Πτολεμαῖος, ; la, Claudius Ptolemaeus; AD) was a mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science. The first is the astronomical treatise now known as the '' Almagest'', although it was originally entitled the ''Mathēmatikē Syntaxis'' or ''Mathematical Treatise'', and later known as ''The Greatest Treatise''. The second is the ''Geography'', which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the ''Apotelesmatika'' (lit. "On the Effects") but more commonly known as the '' Tetrábiblos'', from the Koine Greek meaning "Four Books", or by its Latin equivalent ''Quadripart ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Desert Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid sub ...

Muhammad Al-Mahdi As-Senussi
Muhammad Al Mahdi bin Sayyid Muhammad es Senussi ( ar, محمد المهدي بن سيدي محمد السنوسي), also Sayyid Muhammad ibn Muhammad ibn Muhammad al-Mahdi Ali al-Sanusi, (1844–1902), was the supreme leader of the Sufi Senussi Order between 1859 and his death in 1902 in Libya.Vikør (1995), p. 152. Early years Muhammad Al-Mahdi was the son of the founder of the Senussi Order, Muhammad ibn Ali as-Senussi. He was born in the town of Bayda in northern Cyrenaica, present day northeastern Libya,Vikør (1995), p. 51. He succeeded his father after his death as leader in 1859. Ottoman interference had forced the Senussi to leave coastal Bayda for the desert village of Jaghbub in 1856, where they built an Islamic university, mosque and palace. The later Senussi and Libyan leader King Idris was born here.Bertarelli (1929), p. 419. Kufra In 1895 following interference by the Ottomans Al-Mahdi moved again, much further south to the Kufra oasis in the Libyan Desert subreg ...

El Tag
El Tag (; also ''Al-Tag'', ''Al-Taj'') is a village and holy site in the Kufra Oasis, within the Libyan Desert subregion of the Sahara. It is in the Kufra District in the southern Cyrenaica region of southeastern Libya. The Arabic ''el tag'' translates as "crown" in English, and derives from the position above the Kufra basin.Bertarelli (1929), p. 515. El Tag, being on a rise, is without an oasis spring and native date palm habitat. Senussi El-Tag was founded in 1895 by Muhammad El-Mahdi es-Senussi (1844–1902), after the Ottomans forced him and the Senussi Order from Jaghbub in the Cyrenaican desert to Kufra. He was the son of the founder and the supreme leader (1859-1902) of the Order. El-Mahdi founded a Zaouia (''madrassa''—school) with a mosque a low octagonal minaret tower here. He also built several tombs of the Senussi family here, which later included his own therefore making El-Tag a Senussi holy place. Italians and World War II During the colonial Italian Libya per ...

Arecaceae
The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history. Many common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their importance as ...

Kufra Airport
Kufra Airport is an airport serving Al Jawf, capital of the Kufra District in southeastern Libya. The airport is just east of the city. History Kufra Airport began as Buma Airfield, built in the 1930s as a minor facility by the Italians. In early World War II, it provided an air link to Italian East Africa (Ethiopia, Eritrea, and Italian Somaliland). It was captured by Free French units under General Leclerc on 1 March 1941 along with Kufra Oasis. In April 1942 a detachment of Squadron 16 of the South African Air Force with three Bristol Blenheim Mk. IV aircraft was ordered to Kufra under the command of Major J.L.V. de Wet to strengthen the garrison air defences. On the morning of 4 May 1942 the three aircraft took off on a familiarization mission. They became lost and landed about 150 kilometres North East of Kufra. A sandstorm thwarted ground and air search parties, and by the time the lost aircraft were located on 11 May only one of the total 12-man crew was alive. On 2 ...
