Flag Of Jordan
The flag of Jordan, officially adopted on 16 April 1928, is based on the 1916 flag of the Arab Revolt against the Ottoman Empire during World War I. The flag consists of horizontal black, white, and green bands that are connected by a red chevron. The colours are the Pan-Arab Colors, respectively representing the Abbasid (black band), Umayyad (white band), and Fatimid or Rashidun caliphates (green band). The red chevron is for the Hashemite dynasty, and the Arab Revolt. Features In addition to the bands and chevron, a white star with seven points is featured on the hoist side of the red chevron. The star stands for the unity of the Arab people; its seven points refer to the seven verses of Al-Fatiha as well as the seven hills Amman was built on.

Triband (flag)
A triband is a vexillological style which consists of three stripes arranged to form a flag. These stripes may be two or three colors, and may be charged with an emblem in the middle stripe. Design Outside of the name, which requires three bands of color, there are no other requirements for what a triband must look like, so there are many flags that look very different from each other but are all considered tribands. Some triband flags (e.g. those of Croatia and Ghana) have their stripes positioned horizontally, while others (e.g. that of Italy) position the stripes vertically. Often the stripes on a triband are of equal length and width, though this is not always the case, as can be seen in the flags of Colombia and Canada. Symbols on tribands may be seals, such as on the Belizean flag, or any manner of emblems of significance to the area the flag represents, such as in the flags of Argentina, India and Lebanon. A triband is also a tricolor if the three stripes on the flag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Intelligence Agency
The Central Intelligence Agency (CIA ), known informally as the Agency and historically as the Company, is a civilian foreign intelligence service of the federal government of the United States, officially tasked with gathering, processing, and analyzing national security information from around the world, primarily through the use of human intelligence (HUMINT) and performing covert actions. As a principal member of the United States Intelligence Community (IC), the CIA reports to the Director of National Intelligence and is primarily focused on providing intelligence for the President and Cabinet of the United States. President Harry S. Truman had created the Central Intelligence Group under the direction of a Director of Central Intelligence by presidential directive on January 22, 1946, and this group was transformed into the Central Intelligence Agency by implementation of the National Security Act of 1947. Unlike the Federal Bureau of Investigation (FBI), which is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ghassanids
The Ghassanids ( ar, الغساسنة, translit=al-Ġasāsina, also Banu Ghassān (, romanized as: ), also called the Jafnids, were an Arab tribe which founded a kingdom. They emigrated from southern Arabia in the early 3rd century to the Levant region. Some merged with Hellenized Christian communities, converting to Christianity in the first few centuries AD, while others may have already been Christians before emigrating north to escape religious persecution. After settling in the Levant, the Ghassanids became a client state to the Byzantine Empire and fought alongside them against the Persian Sassanids and their Arab vassals, the Lakhmids. The lands of the Ghassanids also acted as a buffer zone protecting lands that had been annexed by the Romans against raids by Bedouin tribes. Few Ghassanids became Muslim following the Muslim conquest of the Levant; most Ghassanids remained Christian and joined Melkite and Syriac communities within what is now Jordan, Israel, Palesti ...

Tanukhids
The Tanûkhids ( ar, التنوخيون, transl=al-Tanūḫiyyūn) or Tanukh ( ar, تنوخ, translit=Tanūḫ) or Banū Tanūkh (, romanized as: ) were a confederation of Arab tribes, sometimes characterized as Saracens. They first rose to prominence in northern Arabia and southern Syria in the 2nd century CE. Both Lakhmid and Tanukhid inscriptions have been found at Umm el-Jimal in Jordan and Namara in Syria. The ancient Tanukh tribal confederation was largely taken over by several branches of the large Azd and Quda'a tribes. Their main base during the time of their most famous ruler, Queen Mavia, was in Aleppo. During the 8th and 9th centuries, the Tanukhid strongholds were the cities of Qinnasrin and Maarat al-Numan. History In the late 2nd century, a branch of the tribe of Azd, from Southern Arabia, migrated to al-Hasa where Tanukhids were settling. The Azdies allied with the Tanukhids, becoming part of the confederation. The two sheikhs (tribal leaders) gave up the rule t ...

CMYK Color Model
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation ''CMYK'' refers to the four ink plates used: cyan, magenta, yellow, and key (black). The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called ''subtractive'' because inks "subtract" the colors red, green and blue from white light. White light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. In additive color models, such as RGB, white is the "additive" combination of all primary colored lights, black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, black results from a full combination of colo ...

Hexadecimal
In mathematics and computing, the hexadecimal (also base-16 or simply hex) numeral system is a positional numeral system that represents numbers using a radix (base) of 16. Unlike the decimal system representing numbers using 10 symbols, hexadecimal uses 16 distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9, and "A"–"F" (or alternatively "a"–"f") to represent values from 10 to 15. Software developers and system designers widely use hexadecimal numbers because they provide a human-friendly representation of binary-coded values. Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble). For example, an 8-bit byte can have values ranging from 00000000 to 11111111 in binary form, which can be conveniently represented as 00 to FF in hexadecimal. In mathematics, a subscript is typically used to specify the base. For example, the decimal value would be expressed in hexadecimal as . In programming, a number of ...

RGB Color Model
The RGB color model is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography. Before the electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors. RGB is a ''device-dependent'' color model: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual red, green, and blue levels vary from manufacturer to manufacturer, or even in the same device over time. Thus an RGB value does not define the same ''color'' across d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

:en:Abbasid Dynasty
The Abbasid dynasty or Abbasids ( ar, بنو العباس, Banu al-ʿAbbās) were an Arab dynasty that ruled the Abbasid Caliphate between 750 and 1258. They were from the Qurayshi Hashimid clan of Banu Abbas, descended from Abbas ibn Abd al-Muttalib. The Abbasid Caliphate is divided into three main periods: Early Abbasid era (750–861), Middle Abbasid era (861–936) and Later Abbasid era (936–1258). A cadet branch of the dynasty also ruled as ceremonial rulers for the Mamluk Sultanate as Caliph (1261–1517), until their conquest by the Ottoman Empire. Ancestry The Abbasids descended from Abbas, one of Muhammad's companions (as well as his uncle) and one of the early Qur'an scholars. Therefore, their roots trace back to Hashim ibn 'Abd Manaf and also Adnan in the following line: Al-‘Abbas ibn Abdul-Muttalib ibn Hashim ibn Abd Manaf ibn Qusai ibn Kilab ibn Murrah ibn Ka'b ibn Lu'ay ibn Ghalib ibn Fihr ibn Malik ibn An-Nadr ibn Kinanah ibn Khuzaima ibn Mudrikah ibn Ilya ...

:en:Rashidun Caliphate
The Rashidun Caliphate ( ar, اَلْخِلَافَةُ ٱلرَّاشِدَةُ, al-Khilāfah ar-Rāšidah) was the first caliphate to succeed the Islamic prophet Muhammad. It was ruled by the first four successive caliphs of Muhammad after his death in 632 CE (11 AH). During its existence, the empire was the most powerful economic, cultural, and military force in West Asia. The caliphate arose following Muhammad’s passing in June 632 and the subsequent debate over the succession to his leadership. Muhammad's childhood friend and close companion Abu Bakr (), of the Banu Taym clan, was elected the first caliph in Medina and he began the conquest of the Arabian Peninsula. His brief reign ended in August 634 when he died and was succeeded by Umar (), his appointed successor from the Banu Adi clan. Under Umar, the caliphate expanded at an unprecedented rate, ruling more than two-thirds of the Byzantine Empire and nearly the entire Sasanian Empire. Umar was assassinated in Novem ...

:en:Fatimid Dynasty
The Fatimid dynasty () was an Isma'ili Shi'a dynasty of Arab descent that ruled an extensive empire, the Fatimid Caliphate, between 909 and 1171 CE. Claiming descent from Fatima and Ali, they also held the Isma'ili imamate, claiming to be the rightful leaders of the Muslim community. The line of Nizari Isma'ili imams, represented today by the Aga Khans, claims descent from a branch of the Fatimids. The Fatimid dynasty emerged as the leaders of the clandestine early Isma'ili missionary movement () in the ninth century CE, ostensibly acting on behalf of a hidden imam, implied at the time to be Muhammad ibn Isma'il. The Isma'ili spread widely across the Islamic world, then ruled by the Abbasid Caliphate. In 899, the future first Fatimid caliph, Abdallah, proclaimed himself to be the expected imam, causing a rift in the Isma'ili as the Qarmatians, who did not recognize his imamate, split off. In the meantime, Isma'ili agents had managed to conquer large parts of Yemen and Ifriqiya, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
:en:Umayyad Dynasty
Umayyad dynasty ( ar, بَنُو أُمَيَّةَ, Banū Umayya, Sons of Umayya) or Umayyads ( ar, الأمويون, al-Umawiyyūn) were the ruling family of the Caliphate between 661 and 750 and later of Al-Andalus between 756 and 1031. In the pre-Islamic period, they were a prominent clan of the Meccan tribe of Quraysh, descended from Umayya ibn Abd Shams. Despite staunch opposition to the Islamic prophet Muhammad, the Umayyads embraced Islam before the latter's death in 632. Uthman, an early companion of Muhammad from the Umayyad clan, was the third Rashidun caliph, ruling in 644–656, while other members held various governorships. One of these governors, Mu'awiya I of Syria, opposed Caliph Ali in the First Muslim Civil War (656–661) and afterward founded the Umayyad Caliphate with its capital in Damascus. This marked the beginning of the Umayyad dynasty, the first hereditary dynasty in the history of Islam, and the only one to rule over the entire Islamic world of its ti ...
