History Of Espionage
Spying, as well as other intelligence assessment, has existed since ancient history. 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 intelligenc ...

1 (one, unit, unity) is a number, Numeral (linguistics), numeral, and glyph. It is the first and smallest Positive number, positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit (measurement), unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In Digital electronics, digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In math ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greece
Ancient Greece () was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity (), that comprised a loose collection of culturally and linguistically related city-states and communities. Prior to the Roman period, most of these regions were officially unified only once under the Kingdom of Macedon from 338 to 323 BC. In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Three centuries after the decline of Mycenaean Greece during the Bronze Age collapse, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical Greece, from the Greco-Persian Wars to the death of Alexander the Great in 323 BC, and which included the Golden Age of Athens and the Peloponnesian War.

Cryptography
Cryptography, or cryptology (from "hidden, secret"; and ''graphein'', "to write", or ''-logy, -logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of Adversary (cryptography), adversarial behavior. More generally, cryptography is about constructing and analyzing Communication protocol, 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 (confidentiality, data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, Smart card#EMV, chip-based payment cards, digital currencies, password, computer passwords, and military communications. ...

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 Roman symbol of Britannia (a female personification of Great Britain) was revived 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 sep ... [...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. There is one famous incident where a tribe declined rice from another tribe, beginning a long and bloody clan war. The ''pochteca'' are the subject of Book 9 of the '' Florentine Codex'' (1576), compiled by Bernardino de Sahagún.

Aztecs
The Aztecs ( ) were a Mesoamerican civilization that flourished in central Mexico in the post-classic period from 1300 to 1521. The Aztec people included different ethnic groups of central Mexico, particularly those groups who spoke the 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, the capital city of the Mexica or Tenochca, Tetzcoco, and Tlacopan, previously part of the Tepanec empire, whose dominant power was Azcapotzalco. Although the term Aztecs is often narrowly restricted to the Mexica of Tenochtitlan, it is also broadly used to refer to Nahua polities or peoples of central Mexico in the prehispanic era, as well as the Spanish colonial era (1521–1821).

Shinobi
A , or was a spy and infiltrator in pre-modern Japan. The functions of a ninja included siege and infiltration, ambush, reconnaissance, espionage, deception, and later bodyguarding.Kawakami, pp. 21–22 Antecedents may have existed as early as the 12th century. There is little evidence that they were assassins. In the unrest of the Sengoku period, ''jizamurai'' families, that is, elite peasant-warriors, in Iga Province and the adjacent Kōka District formed ''ikki'' – "revolts" or "leagues" – as a means of self-defense. They became known for their military activities in the nearby regions and sold their services as mercenaries and spies. It is from these areas that much of the knowledge regarding the ninja is drawn. Following the Tokugawa shogunate in the 17th century, the ninja faded into obscurity. A number of ''shinobi'' manuals, often based on Chinese military philosophy, were written in the 17th and 18th centuries, most notably the ''Bansenshūkai'' (1676).; bas ...

Feudal Japan
The first human inhabitants of the Japanese archipelago have been traced to the Paleolithic, around 38–39,000 years ago. The Jōmon period, named after its cord-marked pottery, was followed by the Yayoi period in the first millennium BC when new inventions were introduced from Asia. During this period, the first known written reference to Japan was recorded in the Chinese '' Book of Han'' in the first century AD. Around the 3rd century BC, the Yayoi people from the continent immigrated to the Japanese archipelago and introduced iron technology and agricultural civilization. Because they had an agricultural civilization, the population of the Yayoi began to grow rapidly and ultimately overwhelmed the Jōmon people, natives of the Japanese archipelago who were hunter-gatherers. Between the fourth and ninth centuries, Japan's many kingdoms and tribes gradually came to be unified under a centralized government, nominally controlled by the Emperor of Japan.

Mongol Empire
The Mongol Empire was the List of largest empires, largest contiguous empire in human history, history. Originating in present-day Mongolia in East Asia, the Mongol Empire at its height stretched from the Sea of Japan to parts of Eastern Europe, extending northward into parts of the Arctic; eastward and southward into parts of the Indian subcontinent, mounting invasions of Southeast Asia, and conquering the Iranian plateau; and reaching westward as far as the Levant and the Carpathian Mountains. The Mongol Empire emerged from the unification of several nomad, nomadic tribes in the Mongol heartland under the leadership of Temüjin, known by the title of Genghis Khan (–1227), whom a council proclaimed as the ruler of all Mongols in 1206.
