Siege in the context of "Siege of Warsaw (1939)"

The Fall of Constantinople, also known as the Conquest of Constantinople, was the capture of the capital of the Byzantine Empire by the Ottoman Empire. The city was captured on 29 May 1453 as part of the culmination of a 53-day siege which had begun on 6 April.

The attacking Ottoman Army, which significantly outnumbered Constantinople's defenders, was commanded by the 21-year-old Sultan Mehmed II (later nicknamed "the Conqueror"), while the Byzantine army was led by Emperor Constantine XI Palaiologos. After conquering the city, Mehmed II made Constantinople the new Ottoman capital, replacing Adrianople.

Although long walls were built at several locations in ancient Greece, notably Corinth and Megara, the term Long Walls (Ancient Greek: Μακρὰ Τείχη [makra tei̯kʰɛː]) generally refers to the walls that connected Athens' main city to its ports at Piraeus and Phaleron.

Built in several phases, they provided a secure connection to the sea even during times of siege. The walls were about 6 km (3.7 mi) in length. They were initially constructed in the mid-5th century BC, and destroyed by the Spartans in 403 BC after Athens' defeat in the Peloponnesian War. They were rebuilt with Persian support during the Corinthian War in 395–391 BC.

The Shimabara Rebellion (島原の乱, Shimabara no ran), also known as the Shimabara-Amakusa Rebellion (島原･天草の乱, Shimabara-Amakusa no ran) or Shimabara-Amakusa Ikki (島原･天草一揆), was an uprising that occurred in the Shimabara Domain of the Tokugawa shogunate in Japan from 17 December 1637 to 15 April 1638.

Matsukura Katsuie, the daimyō of the Shimabara Domain, enforced unpopular policies set by his father Matsukura Shigemasa that drastically raised taxes to construct the new Shimabara Castle and violently prohibited Christianity. In December 1637, an alliance of local rōnin and mostly Catholic peasants led by Amakusa Shirō rebelled against the Tokugawa shogunate due to discontent over Katsuie's policies. The Tokugawa shogunate sent a force of over 125,000 troops supported by the Dutch to suppress the rebels, which defeated the rebels after a lengthy siege against their stronghold at Hara Castle in Minamishimabara.

Early thermal weapons, which used heat or burning action to destroy or damage enemy personnel, fortifications or territories, were employed in warfare during the ancient and post-classical periods (approximately the 8th century BC until the mid-16th century AD).

Incendiary devices were frequently used as projectiles during warfare, particularly during sieges and naval battles: some substances were boiled or heated to inflict damage by scalding or burning; other substances relied on their chemical properties to inflict burns or damage. These weapons or devices could be used by individuals, thrown by siege engines, or utilised as army strategy. Incendiary mixtures, such as the petroleum-based Greek fire, could be launched by throwing machines or administered through a siphon. Sulfur- and oil-soaked materials were sometimes ignited and thrown at the enemy, or attached to spears, arrows and bolts and fired by hand or machine.

Artillery consists of ranged weapons that launch munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons were developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower.

Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannon, and in contemporary usage, usually refers to shell-firing guns, howitzers, and mortars (collectively called barrel artillery, cannon artillery or gun artillery) and rocket artillery. In common speech, the word "artillery" is often used to refer to individual devices, along with their accessories and fittings, although these assemblages are more properly called "equipment". However, there is no generally recognized generic term for a gun, howitzer, mortar, and so forth: the United States uses "artillery piece", but most English-speaking armies use "gun" and "mortar". The projectiles fired are typically either "shot" (if solid) or "shell" (if not solid). Historically, variants of solid shot including canister, chain shot and grapeshot were also used. "Shell" is a widely used generic term for a projectile, which is a component of munitions.

In Christian eschatology, the Great Tribulation (Ancient Greek: θλῖψις μεγάλη, romanized: thlîpsis megálē) is a period mentioned by Jesus in the Olivet Discourse as a sign that would occur in the time of the end.

At Revelation 7:14, "the Great Tribulation" (Ancient Greek: τῆς θλῑ́ψεως τῆς μεγάλης, romanized: tês thlī́pseōs tês megálēs, lit. 'the great tribulation') is used to indicate the period spoken of by Jesus. Matthew 24:21, 29 uses tribulation (θλίβω) in a context denoting afflictions of those hard-pressed by siege and the calamities of war.

Gylippus (/dʒɪˈlɪpəs/; Greek: Γύλιππος) was a Spartan general (strategos) of the 5th century BC; he was the son of Cleandridas, who was the adviser of King Pleistoanax and had been expelled from Sparta for accepting Athenian bribes in 446 BC and fled to Thurii, a pan-Hellenic colony then being founded in the instep of Italy with Athenian help and participation. His mother may have been a helot, which meant he was not a true Spartiate but a mothax, a man of inferior status. Despite this, from an early childhood he was trained for war in the traditional Spartan fashion and on reaching maturity had been elected to a military mess, his dues contributed by a wealthier Spartiate patron. For an individual of marginal origins, war was an opportunity to gain honor and eminence.

When Alcibiades urged the Spartans to send a general to lead the Syracusan resistance against the Athenian expedition, Gylippus was appointed (414 BC), his arrival was a turning point of the struggle. More daring than Nicias, the Athenian commander he faced, he was able to gain an upper hand by driving the Athenians from key strategic locations and essentially breaking the siege. When Athens sent Demosthenes with reinforcements, he too was defeated by Gylippus, which ultimately led to the downfall of the Athenian campaign in Syracuse.

A siege tower or breaching tower (or in the Middle Ages, a belfry) is a specialized siege engine, constructed to protect assailants and ladders while approaching the defensive walls of a fortification. The tower was often rectangular with four wheels with its height roughly equal to that of the wall or sometimes higher to allow archers or crossbowmen to stand on top of the tower and shoot arrows or quarrels into the fortification. While the towers were primarily constructed of wood and thus flammable, their builders typically incorporated whatever non-flammable coverings could be readily procured including iron and/or fresh animal skins.

Evidence for use of siege towers in Ancient Egypt and Anatolia dates to the Bronze Age. They were used extensively in warfare of the ancient Near East after the Late Bronze Age collapse, and in Egypt by Kushites from Sudan who founded the 25th dynasty. During classical antiquity they were common among Hellenistic Greek armies of the 4th century BC and later Roman armies of Europe and the Mediterranean, while also seeing use in ancient China during the Warring States Period and Han dynasty. Siege towers were of unwieldy dimensions and, like trebuchets, were therefore mostly constructed on site of the siege. Taking considerable time to construct, siege towers were mainly built if the defense of the opposing fortification could not be overcome by ladder assault ("escalade"), by mining, or by breaking walls or gates with tools such as battering rams.

The Arauco War was a long-running conflict between colonial Spaniards and the Mapuche people, mostly fought in the Araucanía region of Chile. The conflict began at first as a reaction to the Spanish conquerors attempting to establish cities and force Mapuches into servitude. It subsequently evolved over time into phases comprising drawn-out sieges, slave-hunting expeditions, pillaging raids, punitive expeditions, and renewed Spanish attempts to secure lost territories. Abduction of women and war rape was common on both sides.

The Spaniards penetrated into Mapuche territory during the conquest of Chile until the Battle of Curalaba in 1598 and the following destruction of the Seven Cities led to the establishment of a clear frontier between the Spanish domains and the land of the independent Mapuche. From the 17th to the late 18th century a series of parliaments were held between royal governors and Mapuche lonkos and the war devolved to sporadic pillaging carried out by both sides.
