  "text": "The Roman Empire ( ; ) was the post-Republican period of ancient Rome. 
As a polity, it included large territorial holdings around the Mediterranean Sea in Europe, North Africa, and Western Asia, and was ruled by emperors. From the accession of Caesar Augustus as the first Roman emperor to the military anarchy of the 3rd century, it was a Principate with Italia as the metropole of its provinces and the city of Rome as its sole capital. The Empire was later ruled by multiple emperors who shared control over the Western Roman Empire and the Eastern Roman Empire. The city of Rome remained the nominal capital of both parts until AD 476 when the imperial insignia were sent to Constantinople following the capture of the Western capital of Ravenna by the Germanic barbarians. The adoption of Christianity as the state church of the Roman Empire in AD 380 and the fall of the Western Roman Empire to Germanic kings conventionally marks the end of classical antiquity and the beginning of the Middle Ages. Because of these events, along with the gradual Hellenization of the Eastern Roman Empire, historians distinguish the medieval Roman Empire that remained in the Eastern provinces as the Byzantine Empire.",

  "id": "Internal combustion engine",
  "text": "An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons (piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle (jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important.",

New York City traces its origins to a trading post founded on the southern tip of Manhattan Island by Dutch colonists in 1624. The settlement was named New Amsterdam in 1626 and was chartered as a city in 1653. Because of the history of Dutch colonization, Dutch culture, politics, law, architecture, and language played a formative role in shaping the culture of the city. The Dutch were the majority in New York City until the early 1700s and the Dutch language was commonly spoken until the mid to late-1700s. Many places and institutions in New York City still bear a colonial Dutch toponymy, including Brooklyn (Breukelen), Harlem (Haarlem), Wall Street (Waal Straat), The Bowery (bouwerij (\u201cfarm\u201d), and Coney Island (conyne).",
