Prague has been a political, cultural, and economic centre of central Europe with waxing and waning fortunes during its 1,100-year existence. Founded during the Romanesque and flourishing by the Gothic and Renaissance eras, Prague was not only the capital of the Czech state, but also the seat of two Holy Roman Emperors and thus then also the capital of the Holy Roman Empire. It was an important city to the Habsburg Monarchy and its Austro-Hungarian Empire and after World War I became the capital of Czechoslovakia. The city played major roles in the Protestant Reformation, the Thirty Years' War, and in 20th-century history, during both World Wars and the post-war Communist era.

In 2011, Prague was the sixth-most-visited city in Europe. The name Prague is derived from an old Slavic root, praga, which means "ford", referring to the city's origin at a crossing point of the Vltava river. The native name of the city, Praha, however, is also related to the modern Czech word práh (threshold) and a legendary etymology connects the name of the city with princess Libuše, prophetess and a wife of mythical founder of the Přemyslid dynasty. She is said to have ordered the city "to be built where a man hews a threshold of his house". The Czech práh might thus be understood to refer to rapids or a cataract in the river, the edge of which could have acted as a means of fording the river thus providing a "threshold" to the castle. However, no geological ridge in the river has ever been located directly beneath the castle. The same etymology is associated with the Praga district of Warsaw. Another derivation of the name Praha is suggested from na prazě, the original term for the shale hillside rock upon which the original castle was built. At that time, the castle was surrounded by forests, covering the nine hills of the future city the Old Town on the opposite side of the river, as well as the Lesser Town beneath the existing castle, appeared only later. Nicknames for Prague have included: Praga mater urbium/Praha matka měst ("Prague Mother of Cities") in Latin/Czech, Stověžatá Praha ("City of a Hundred Spires") based on count by 19 century mathematician Bernard Bolzano. Today's count is estimated at 500.
