Stronghold
A fortification (also called a fort, fortress, fastness, or stronghold) is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin ("strong") and ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley Civilization were the first small cities to be fortified. In ancient Greece, large cyclopean stone walls fitted without mortar had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted as a bor ...

Hill Fort
A hillfort is a type of fortification, fortified refuge or defended settlement located to exploit a rise in elevation for defensive advantage. They are typical of the late Bronze Age Europe, European Bronze Age and Iron Age Europe, Iron Age. Some were used in the post-Roman Empire, Roman period. The fortification usually follows the contours of a hill and consists of one or more lines of Earthworks (Archaeology), earthworks or stone Rampart (fortification), ramparts, with stockades or defensive walls, and external ditches. If enemies were approaching, the inhabitants would spot them from a distance. Prehistoric Europe saw a growing population. It has been estimated that in about 5000 BC during the Neolithic between 2 million and 5 million lived in Europe; in the Late Iron Age it had an estimated population of around 15 to 30 million. Outside Greece and Italy, which were more densely populated, the vast majority of settlements in the Iron Age were small, with ...

Ancient Roman
In modern historiography, ancient Rome is the Roman people, Roman civilisation from the founding of Rome, founding of the Italian city of Rome in the 8th century BC to the Fall of the Western Roman Empire, collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (50927 BC), and the Roman Empire (27 BC476 AD) until the fall of the western empire. Ancient Rome began as an Italic peoples, 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 controlled the Italian Peninsula, assimilating the Greece, Greek culture of southern Italy (Magna Graecia) and the Etruscans, Etruscan culture, and then became the dominant power in the Mediterranean region and parts of Europe.

Mycenae
Mycenae ( ; ; or , ''Mykē̂nai'' or ''Mykḗnē'') is an archaeological site near Mykines, Greece, Mykines in Argolis, north-eastern Peloponnese, Greece. It is located about south-west of Athens; north of Argos, Peloponnese, Argos; and south of Corinth. The site is inland from the Saronic Gulf and built upon a hill rising above sea level. In the second millennium BC, Mycenae was one of the major centres of Greek civilisation, a military stronghold which dominated much of southern Greece, Crete, the Cyclades and parts of southwest Anatolia. The period of History of Greece, Greek history from about 1600 BC to about 1100 BC is called Mycenaean Greece, Mycenaean in reference to Mycenae. At its peak in 1350 BC, the citadel and lower town had a population of 30,000 and an area of . The first correct identification of Mycenae in modern literature was in 1700, during a survey conducted by the Venetian engineer Francesco Vandeyk on behalf of Francesco Grimani, the Provveditore Ge ...

Castle
A castle is a type of fortification, fortified structure built during the Middle Ages predominantly by the nobility or royalty and by Military order (monastic society), military orders. Scholars usually consider a ''castle'' to be the private fortified house, fortified residence of a lord or noble. This is distinct from a mansion, palace, and villa, whose main purpose was exclusively for ''pleasance'' and are not primarily fortresses but may be fortified. Use of the term has varied over time and, sometimes, has also been applied to structures such as hill forts and 19th- and 20th-century homes built to resemble castles. Over the Middle Ages, when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain wall (fortification), curtain walls, arrowslits, and portcullises, were commonplace. European-style castles originated in the 9th and 10th centuries after the fall of the Carolingian Empire, which resulted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Explosive Shell
A shell, in a modern military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. A shell can hold a tracer. All explosive- and incendiary-filled projectiles, particularly for mortars, were originally called ''grenades'', derived from the French word for pomegranate, so called because of the similarity of shape and that the multi-seeded fruit resembles the powder-filled, fragmentizing bomb. Words cognate with ''grenade'' are still used for an artillery or mortar projectile in some European languages. Shells are usually large-caliber projectiles fired by artillery, armoured fighting vehicles (e.g. tanks, assault guns, and mortar carriers), warships, and autocannons. The shape is usually a cylinder topped by an ogive-tipped nose cone for good aerodynamic performance, and possibly with a tapered boat tail; but some specializ ...

Peacetime
Peace is a state of harmony in the absence of hostility and violence, and everything that discusses achieving human welfare through justice and peaceful conditions. In a societal sense, peace is commonly used to mean a lack of conflict (such as war) and freedom from fear of violence between individuals or groups. Promotion of peace is a core tenet of many philosophies, religions, and ideologies, many of which consider it a core tenet of their philosophy. Some examples are: religions such as Buddhism and Christianity, important figures like Gandhi, and throughout literature like " Perpetual Peace: A Philosophical Sketch" by Immanuel Kant, " The Art of Peace" by Morihei Ueshiba, or ideologies that strictly adhere to it such as Pacifism within a sociopolitical scope. It is a frequent subject of symbolism and features prominently in art and other cultural traditions. The representation of peace has taken many shapes, with a variety of symbols pertaining to it based on culture, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rampart (fortification)
In fortification architecture, a rampart is a length of Embankment (earthworks), embankment or wall forming part of the defensive boundary of a castle, hillfort, Human settlement, settlement or other fortified site. It is usually broad-topped and made of excavated earth and/or masonry.Friar, Stephen (2003). ''The Sutton Companion to Castles'', Sutton Publishing, Stroud, 2003, p. 241. Darvill, Timothy (2008). ''Oxford Concise Dictionary of Archaeology'', 2nd ed., Oxford University Press, Oxford and New York, p. 376. . Types The composition and design of ramparts varied from the simple mounds of earth and stone, known as dump ramparts, to more complex earth and timber defences (box ramparts and timberlaced ramparts), as well as ramparts with stone revetments. One particular type, common in Central Europe, used earth, stone and timber posts to form a ''Pfostenschlitzmauer'' or "post-slot wall". Vitrified ramparts were composed of stone that was subsequently fired, possibly to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ditch (fortification)
In military engineering, a ditch is an obstacle designed to slow down or break up an attacking force, while a Trench warfare, trench is intended to provide cover to the defenders. In military fortifications, the side of a ditch furthest from the enemy and closest to the next line of defence is known as the scarp (fortification), scarp while the side of a ditch closest to the enemy is known as the counterscarp. Uses In early fortifications, ditches were often used in combination with rampart (fortification), ramparts to slow down the enemy whilst defensive fire could be brought to bear from the relative protection afforded by the rampart and possibly the palisade. In medieval fortifications, a ditch was often constructed in front of a defensive wall to hinder Mining (military), mining and escalade activities from an attacker. When filled with water, such a defensive ditch is called a moat. However, moats may also be dry. Star forts designed by military engineers like Vauban, co ...

Black Powder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, charcoal (which is mostly carbon), and potassium nitrate, potassium nitrate (saltpeter). The sulfur and charcoal act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building Pipeline transport, pipelines, tunnels, and road#Construction, roads. Gunpowder is classified as a Explosive#Low, low explosive because of its relatively slow decomposition rate, low ignition temperature and consequently low brisance, brisance (breaking/shattering). Low explosives deflagration, deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonation, detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannon
A cannon is a large-caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge (firearms), gauge, effective range, mobility (military), mobility, rate of fire, elevation (ballistics), angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. The earliest known depiction of cannons may have appeared in Science and technology of the Song dynasty#Gunpowder warfare, Song dynasty China as early as the 12th century; however, solid archaeological and documentary evidence of cannons do ...
