Ottoman wars in Europe

The Ottoman wars in Europe, also known as the Ottoman Wars or Turkish Wars, were a series of military conflicts between the Ottoman Empire and various European states dating from the Late Middle Ages up through the early 20th century. The earliest conflicts began during the Byzantine–Ottoman Wars in the 13th century, followed by the Bulgarian–Ottoman Wars and the Serbian–Ottoman Wars in the 14th century. Much of this period was defined by Ottoman expansion into the Balkans and modern-day Serbia, which allowed the Empire to gain a foothold in eastern Europe. The Ottoman Empire made further inroads into Central Europe in the 15th and 16th centuries, culminating in the peak of Turkish territorial claims in Europe. There was a backslide in Ottoman military dominance after the unsuccessful Siege of Vienna in 1529 and the Ottoman-Habsburg wars. European powers began to consolidate against the Ottomans and formed the Holy League, reversing a number of Ottoman land gains during the Great Turkish War of the late 1600s.

Byzantine Empire

The Byzantine Empire, sometimes referred to as the Eastern Roman Empire, was the continuation of the Roman Empire in the East during Late Antiquity and the Middle Ages, when its capital city was Constantinople (modern-day Istanbul, originally founded as Byzantium). It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, and military force in Europe. Both "Byzantine Empire" and "Eastern Roman Empire" are historiographical terms created after the end of the realm; its citizens continued to refer to their empire as the Roman Empire (Ancient Greek: Βασιλεία τῶν Ῥωμαίων, tr. Basileia tôn Rhōmaiōn; Latin: Imperium Romanum), or Romania (Ῥωμανία), and to themselves as "Romans".

Several events from the 4th to 6th centuries mark the period of transition during which the Roman Empire's Greek East and Latin West divided. Constantine I (r. 324–337) reorganised the empire, made Constantinople the new capital, and legalised Christianity. Under Theodosius I (r. 379–395), Christianity became the Empire's official state religion and other religious practices were proscribed. Finally, under the reign of Heraclius (r. 610–641), the Empire's military and administration were restructured and adopted Greek for official use instead of Latin. Thus, although the Roman state continued and Roman state traditions were maintained, modern historians distinguish Byzantium from ancient Rome insofar as it was centred on Constantinople, oriented towards Greek rather than Latin culture, and characterised by Orthodox Christianity.

Total war

Total war is warfare that includes any and all civilian-associated resources and infrastructure as legitimate military targets, and typically involves the use of weapons and tactics that result in significant civilian or other non-combatant casualties, whether collateral damage or not. American-English Dictionary defines "total war" as "war that is unrestricted in terms of the weapons used, the territory or combatants involved, or the objectives pursued, especially one in which the laws of war are disregarded." The term can also be applied when the war effort requires significant sacrifices by most of the friendly civilian population.

In the mid-19th century, scholars identified "total war" as a separate class of warfare. In a total war, to an extent inapplicable to less total conflicts, the differentiation between combatants and non-combatants diminishes and even sometimes vanishes entirely as opposing sides can consider nearly every human resource, even that of non-combatants, as nevertheless part of the war effort.

Empire

An empire is defined as "an aggregate of nations or people ruled over by an emperor or other powerful sovereign or government, usually a territory of greater extent than a kingdom, as the former British Empire, French Empire, Spanish Empire, Russian Empire, Byzantine Empire or Roman Empire." An empire can be made solely of contiguous territories such as the Austro-Hungarian Empire, or of territories far remote from the homeland, such as a colonial empire.

Aside from the more formal usage, the term "empire" can also be used to refer to a large-scale business enterprise (e.g. a transnational corporation), a political organisation controlled by a single individual (a political boss) or a group (political bosses). The term "empire" is associated with other words such as imperialism, colonialism, and globalization. Empire is often used to describe a displeasure to overpowering situations. The effects of imperialism exist throughout the world today.

An imperial political structure can be established and maintained in two ways: (i) as a territorial empire of direct conquest and control with force or (ii) as a coercive, hegemonic empire of indirect conquest and control with power. The former method provides greater tribute and direct political control, yet limits further expansion because it absorbs military forces to fixed garrisons. The latter method provides less tribute and indirect control, but avails military forces for further expansion. Territorial empires (e.g., the Mongol Empire and Median Empire) tend to be contiguous areas. The term, on occasion, has been applied to maritime empires or thalassocracies, (e.g., the Athenian and British empires) with looser structures and more scattered territories. Empires are usually larger than kingdoms.

Ottoman Empire

The Ottoman Empire (/ˈɒtəmən/; Ottoman Turkish: دَوْلَتِ عَلِيّهٔ عُثمَانِیّه‎ Devlet-i Aliyye-i Osmâniyye, Modern Turkish: Osmanlı İmparatorluğu or Osmanlı Devleti), also known as the Turkish Empire, Ottoman Turkey or Turkey, was an empire founded in 1299 by Oghuz Turks under Osman I in northwestern Anatolia. After conquests in the Balkans by Murad I between 1362 and 1389, the Ottoman sultanate was transformed into a transcontinental empire and claimant to the caliphate. The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror.

During the 16th and 17th centuries, in particular at the height of its power under the reign of Suleiman the Magnificent, the Ottoman Empire was a multinational, multilingual empire controlling much of Southeast Europe, Western Asia, the Caucasus, North Africa, and the Horn of Africa. At the beginning of the 17th century the empire contained 32 provinces and numerous vassal states. Some of these were later absorbed into the Ottoman Empire, while others were granted various types of autonomy during the course of centuries.
