TurkeyTurkey (Türkiye, ˈtyɾcije), officially the Republic of Türkiye (Türkiye Cumhuriyeti ˈtyɾcije dʒumˈhuːɾijeti), is a country located mainly on the Anatolian Peninsula in West Asia, with a small portion on the Balkan Peninsula in Southeast Europe. It borders the Black Sea to the north; Georgia to the northeast; Armenia, Azerbaijan, and Iran to the east; Iraq to the southeast; Syria and the Mediterranean Sea to the south; the Aegean Sea to the west; and Greece and Bulgaria to the northwest. Cyprus is off the south coast.
Cable-stayed bridgeA cable-stayed bridge has one or more towers (or pylons), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers.
Orient ExpressThe Orient Express was a long-distance passenger train service created in 1883 by the Belgian company Compagnie Internationale des Wagons-Lits (CIWL) that operated until 2009. The train traveled the length of continental Europe, with main terminal stations in Paris in the northwest and Istanbul in the southeast, and branches extending service to Athens, Brussels, and London. The route and rolling stock of the Orient Express changed many times. Several routes in the past concurrently used the Orient Express name, or slight variations.
Postal codeA postal code (also known locally in various English-speaking countries throughout the world as a postcode, post code, PIN or ZIP Code) is a series of letters or digits or both, sometimes including spaces or punctuation, included in a postal address for the purpose of sorting mail. the Universal Postal Union lists 160 countries which require the use of a postal code. Although postal codes are usually assigned to geographical areas, special codes are sometimes assigned to individual addresses or to institutions that receive large volumes of mail, such as government agencies and large commercial companies.
Porphyry (geology)Porphyry (ˈpɔrfəri ) is any of various decorative granites or igneous rocks with coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate-rich, generally aphanitic matrix or groundmass. The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term porphyry usually refers to the purple-red form of this stone, valued for its appearance, but other colours of decorative porphyry are also used such as "green", "black" and "grey".
Suspension bridgeA suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges.
Ottoman EmpireThe Ottoman Empire, historically and colloquially known as the Turkish Empire, was an empire that controlled much of Southeast Europe, Western Asia, and Northern Africa between the 14th and early 20th centuries. It was founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt (modern-day Bilecik Province) by the Turkoman tribal leader Osman I. After 1354, the Ottomans crossed into Europe and, with the conquest of the Balkans, the Ottoman beylik was transformed into a transcontinental empire.
Ottoman CaliphateThe caliphate of the Ottoman Empire (hilâfet makamı) was the claim of the heads of the Turkish Ottoman dynasty to be the caliphs of Islam in the late medieval and the early modern era. During the period of Ottoman expansion, Ottoman rulers claimed caliphal authority after the conquest of Mamluk Egypt by sultan Selim I in 1517, which bestowed the title of Defender of the Holy Cities of Mecca and Medina upon him and strengthened the Ottoman claim to caliphate in the Muslim world.
Walls of ConstantinopleThe Walls of Constantinople (Τείχη της Κωνσταντινουπόλεως) are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul in Turkey) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built.
Ottoman TurksThe Ottoman Turks (Osmanlı Türkleri) were a Turkic ethnic group. They founded the Ottoman Empire in the early modern era and remained sociopolitically the most dominant group in the Empire for the duration ( 1299/1302–1922). Reliable information about the early history of Ottoman Turks remains scarce, but they take their Turkish name, Osmanlı ("Osman" became altered in some European languages as "Ottoman"), from the house of Osman I (reigned 1299–1326), the founder of the House of Osman, the ruling dynasty of the Ottoman Empire for its entire 624 years.
Hagia SophiaHagia Sophia ( 'Holy Wisdom'; Ayasofya; Hagía Sophía; Sancta Sapientia), officially the Hagia Sophia Mosque (Ayasofya-i Kebir Cami-i Şerifi), is a mosque and a major cultural and historical site in Istanbul, Turkey. The last of three church buildings to be successively erected on the site by the Eastern Roman Empire, it was completed in 537 AD. It was an Orthodox church until the Ottoman conquest of Constantinople in 1453, then a mosque until 1935, then a museum and then from 2020 a mosque again, as well as being a Roman Catholic cathedral for some decades after the Fourth Crusade of 1204.
Ottoman dynastyThe Ottoman dynasty (Osmanlı Hanedanı) consisted of the members of the imperial House of Osman (Ḫānedān-ı Āl-i ʿOsmān), also known as the Ottomans (Osmanlılar). According to Ottoman tradition, the family originated from the Kayı tribe branch of the Oghuz Turks, under Osman I in northwestern Anatolia in the district of Bilecik Söğüt. The Ottoman dynasty, named after Osman I, ruled the Ottoman Empire from 1299 to 1922.
Fall of ConstantinopleThe 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.
Sea of MarmaraThe Sea of Marmara, also known as the Marmara Sea, is a small inland sea located entirely within the borders of Turkey. It connects the Black Sea to the Aegean Sea via the Bosporus and Dardanelles straits, separating Turkey’s European and Asian sides. It has an area of , and its dimensions are . Its greatest depth is . The Sea of Marmara is named after the largest island on its south side, called Marmara Island because it is rich in marble (Greek μάρμᾰρον (mármaron) "marble").
Ottoman architectureOttoman architecture is the architectural style that developed under the Ottoman Empire. It first emerged in northwestern Anatolia in the late 13th century and developed from earlier Seljuk Turkish architecture, with influences from Byzantine and Iranian architecture along with other architectural traditions in the Middle East. Early Ottoman architecture experimented with multiple building types over the course of the 13th to 15th centuries, progressively evolving into the classical Ottoman style of the 16th and 17th centuries.
