Monoreme
A galley is a type of ship optimised for propulsion by oars. Galleys were historically used for naval warfare, warfare, Maritime transport, trade, and piracy mostly in the seas surrounding Europe. It developed in the Mediterranean world during Classical antiquity, antiquity and continued to exist in various forms until the early 19th century. It typically had a long, slender hull, shallow draft (hull), draft, and often a low freeboard (nautical), freeboard. Most types of galleys also had sails that could be used in favourable winds, but they relied primarily on oars to move independently of winds and currents or in battle. The term "galley" originated from a Greek term for a small type of galley and came in use in English from about 1300. It has occasionally been used for unrelated vessels with similar military functions as galley but which were not Mediterranean in origin, such as medieval Scandinavian longships, 16th-century Ghali (ship), Acehnese ghalis and 18th-century North ...

Greek Fire
Greek fire was an incendiary weapon system used by the Byzantine Empire from the seventh to the fourteenth centuries. The recipe for Greek fire was a closely-guarded state secret; historians have variously speculated that it was based on saltpeter, sulfur, or quicklime, but most modern scholars agree that it was based on petroleum mixed with resins, comparable in composition to modern napalm. Byzantine sailors would toss grenades loaded with Greek fire onto enemy ships or spray it from tubes. Its ability to burn on water made it an effective and destructive naval incendiary weapon, and rival powers tried unsuccessfully to copy the material. Name Usage of the term "Greek fire" has been general in English and most other languages since the Crusades. Original Byzantine sources called the substance a variety of names, such as "sea fire" (Medieval Greek: ), "Roman fire" ( ), "war fire" ( ), "liquid fire" ( ), "sticky fire" ( ), or "manufactured fire" ( ).

Catapult
A catapult is a ballistics, ballistic device used to launch a projectile at a great distance without the aid of gunpowder or other propellants – particularly various types of ancient and medieval siege engines. A catapult uses the sudden release of stored potential energy to propel its payload. Most convert Tension (mechanics), tension or Torsion (mechanics), torsion energy that was more slowly and manually built up within the device before release, via springs, bows, twisted rope, elastic, or any of numerous other materials and mechanisms which allow the catapult to launch a projectile such as rocks, cannon balls, or debris. During wars in the ancient times, the catapult was usually known to be the strongest heavy weaponry. In modern times the term can apply to devices ranging from a simple hand-held implement (also called a "slingshot") to a mechanism for Aircraft catapult, launching aircraft from a ship. The earliest catapults date to at least the 7th century BC, with Kin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Ram
A ram on the bow of ''Olympias'', a modern reconstruction of an ancient Athenian trireme A naval ram is a weapon fitted to varied types of ships, dating back to antiquity. The weapon comprised an underwater prolongation of the bow of the ship to form an armoured beak, usually between in length. This would be driven into the hull of an enemy ship to puncture, sink or disable it. Antiquity It was possibly developed in late Bronze Age Egypt, but it only became widely used in later Iron Age Mediterranean galleys. The ram was a naval weapon in the Greek/ Roman antiquity and was used in such naval battles as Salamis and Actium. Naval warfare in the Mediterranean rarely used sails, and the use of rams specifically required oarsmen rather than sails in order to maneuver with accuracy and speed, and particularly to reverse the movement of a ramming ship to disentangle it from its sinking victim, lest it be pulled down when its victim sank. The Athenians were especially known fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Middle Ages
The late Middle Ages or late medieval period was the Periodization, period of History of Europe, European history lasting from 1300 to 1500 AD. The late Middle Ages followed the High Middle Ages and preceded the onset of the early modern period (and in much of Europe, the Renaissance). Around 1350, centuries of prosperity and growth in Europe came to a halt. A series of famines and Plague (disease), plagues, including the Great Famine of 1315–1317 and the Black Death, reduced the population to around half of what it had been before the calamities. Along with depopulation came social unrest and endemic warfare. Kingdom of France, France and Kingdom of England, England experienced serious peasant uprisings, such as the Jacquerie and the Peasants' Revolt, as well as over a century of intermittent conflict, the Hundred Years' War. To add to the many problems of the period, the unity of the Catholic Church was temporarily shattered by the Western Schism. Collectively, those events ar ...

High Middle Ages
The High Middle Ages, or High Medieval Period, was the periodization, period of European history between and ; it was preceded by the Early Middle Ages and followed by the Late Middle Ages, which ended according to historiographical convention. Key historical trends of the High Middle Ages include the medieval demography, rapidly increasing population of Europe, which brought about great social and political change from the preceding era, and the Renaissance of the 12th century, including the first developments of rural exodus and urbanization. By 1350, the robust population increase had greatly benefited the European economy, which had reached levels that would not be seen again in some areas until the 19th century. That trend faltered in the early 14th century, as the result of numerous events which together comprised the crisis of the late Middle Ages—most notable among them being the Black Death, in addition to various regional wars and economic stagnation.

Christian Pilgrims
Christianity has a strong tradition of pilgrimages, both to sites relevant to the New Testament narrative (especially in the Holy Land) and to sites associated with later saints or miracles. History Christian pilgrimages were first made to sites connected with the birth, life, crucifixion and resurrection of Jesus. Aside from the early example of Origen in the third century, surviving descriptions of Christian pilgrimages to the Holy Land date from the 4th century, when pilgrimage was encouraged by church fathers including Saint Jerome, and established by Saint Helena, the mother of Constantine the Great. In many places, an extensive infrastructure developed that was specifically geared towards the accommodation and consumption needs of a large number of pilgrims. In the late Middle Ages, there were organised group journeys for pilgrims, mainly by ship from various starting points to Israel. Purpose and motivations The purpose of Christian pilgrimage was summarized by Pope B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, similarly to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—once part of the Byzantine Empire� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibious Warfare
Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles. The term ''amphibious'' first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.The first LVT prototypes were named '' Alligator'' and '' Crocodile'', though neither species is actual amphibian Amphibious warfare includes operations defined by their type, purpose, sca ...
