History Of Espionage
Spying, as well as other intelligence assessment, has existed since ancient times. In the 1980s scholars characterized foreign intelligence as "the missing dimension" of historical scholarship." Since then a largely popular and scholarly literature has emerged. Special attention has been paid to World War II, as well as the Cold War era (1947–1989) that was a favorite for novelists and filmmakers.Raymond L. Garthoff, "Foreign intelligence and the historiography of the Cold War." ''Journal of Cold War Studies'' 6.2 (2004): 21–56. Early history Efforts to use espionage for military advantage are well documented throughout history. Sun Tzu, 4th century BC, a theorist in ancient China who influenced Asian military thinking, still has an audience in the 21st century for the ''Art of War.'' He advised, "One who knows the enemy and knows himself will not be endangered in a hundred engagements." He stressed the need to understand yourself and your enemy for military intelligence. ...

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit (measurement), unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest Positive number, positive integer. It is also sometimes considered the first of the sequence (mathematics), infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally ac ...

Ancient Rome
In modern historiography, ancient Rome refers to Roman civilisation from the founding of the city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC) and Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually dominated the Italian Peninsula, assimilated the Greek culture of southern Italy ( Magna Grecia) and the Etruscan culture and acquired an Empire that took in much of Europe and the lands and peoples surrounding the Mediterranean Sea. It was among the largest empires in the ancient world, with an estimated 50 to 90 million inhabitants, roughly 20% of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seal (device)
A seal is a device for making an impression in wax, clay, paper, or some other medium, including an embossment on paper, and is also the impression thus made. The original purpose was to authenticate a document, or to prevent interference with a package or envelope by applying a seal which had to be broken to open the container (hence the modern English verb "to seal", which implies secure closing without an actual wax seal). The seal-making device is also referred to as the seal ''matrix'' or ''die''; the imprint it creates as the seal impression (or, more rarely, the ''sealing''). If the impression is made purely as a relief resulting from the greater pressure on the paper where the high parts of the matrix touch, the seal is known as a ''dry seal''; in other cases ink or another liquid or liquefied medium is used, in another color than the paper. In most traditional forms of dry seal the design on the seal matrix is in intaglio (cut below the flat surface) and therefore the ...

Thomas Phelippes
Thomas Phelippes (1556–1625), also known as Thomas Phillips was a linguist, who was employed as a forger and intelligence gatherer. He served mainly under Sir Francis Walsingham, in the time of Elizabeth I, and most notably deciphered the coded letters of Babington Plot conspirators. Life and education Little is known about Phelippes family background except that he was the son of a cloth merchant. Despite his humble origins, it is believed that he entered Trinity College, Cambridge, in 1569 and graduated with a Bachelor of Arts in 1574. Phelippes was a linguist who could speak French, Italian, Spanish, Latin and German. His education helped him to master cipher skills and be an excellent cryptographer of high reputation. Therefore, he was employed by Sir Francis Walsingham, the principal secretary to Queen Elizabeth I. The physical and intellectual stature of Phelippes was described as "''a small, lean, yellow-haired, short-sighted man, with pock-marked face, an excellent l ...

Cryptography
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security ( data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elizabethan Era
The Elizabethan era is the epoch in the Tudor period of the history of England during the reign of Queen Elizabeth I (1558–1603). Historians often depict it as the golden age in English history. The symbol of Britannia (a female personification of Great Britain) was first used in 1572, and often thereafter, to mark the Elizabethan age as a renaissance that inspired national pride through classical ideals, international expansion, and naval triumph over Spain. This "golden age" represented the apogee of the English Renaissance and saw the flowering of poetry, music and literature. The era is most famous for its theatre, as William Shakespeare and many others composed plays that broke free of England's past style of theatre. It was an age of exploration and expansion abroad, while back at home, the Protestant Reformation became more acceptable to the people, most certainly after the Spanish Armada was repelled. It was also the end of the period when England was a separate r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Walsingham
Sir Francis Walsingham ( – 6 April 1590) was principal secretary to Queen Elizabeth I of England from 20 December 1573 until his death and is popularly remembered as her "spymaster". Born to a well-connected family of gentry, Walsingham attended Cambridge University and travelled in continental Europe before embarking on a career in law at the age of twenty. A committed Protestant, during the reign of the Catholic Queen Mary I of England he joined other expatriates in exile in Switzerland and northern Italy until Mary's death and the accession of her Protestant half-sister, Elizabeth. Walsingham rose from relative obscurity to become one of the small coterie who directed the Elizabethan state, overseeing foreign, domestic and religious policy. He served as English ambassador to France in the early 1570s and witnessed the St. Bartholomew's Day massacre. As principal secretary, he supported exploration, colonization, the use of England's maritime strength and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pochteca
''Pochteca'' (singular ''pochtecatl'') were professional, long-distance traveling merchants in the Aztec Empire. The trade or commerce was referred to as ''pochtecayotl''. Within the empire, the ''pochteca'' performed three primary duties: market management, international trade, and acting as market intermediaries domestically. They were a small but important class as they not only facilitated commerce, but also communicated vital information across the empire and beyond its borders, and were often employed as spies due to their extensive travel and knowledge of the empire. The ''pochteca'' are the subject of Book 9 of the ''Florentine Codex'' (1576), compiled by Bernardino de Sahagún. Status in Aztec society ''Pochteca'' occupied a high status in Aztec society, below the noble class. They were responsible for providing the materials that the Aztec nobility used to display their wealth, which were often obtained from foreign sources. The ''pochteca'' also acted as agents for the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aztecs
The Aztecs () were a Mesoamerican culture that flourished in central Mexico in the post-classic period from 1300 to 1521. The Aztec people included different Indigenous peoples of Mexico, ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl, Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries. Aztec culture was organized into city-states (''altepetl''), some of which joined to form alliances, political confederations, or empires. The Aztec Empire was a confederation of three city-states established in 1427: Tenochtitlan, city-state of the Mexica or Tenochca; Texcoco (altepetl), Texcoco; and Tlacopan, previously part of the Tepanec empire, whose dominant power was Azcapotzalco (altepetl), Azcapotzalco.
