case of Baden-Württemberg, Stadtkreise ("urban districts"). There are currently 110 kreisfreie Städte (or equivalents).

Stadtstaaten of Germany Two cities in Germany, namely Berlin and Hamburg, are considered city-states (German: Stadtstaaten). Additionally, the state of Bremen is officially classified as a city-state although it consists of the two cities of Bremen and Bremerhaven, which are separated by the state of Lower Saxony. Together with thirteen area states (German: Flächenländer) they form the sixteen federal states of Germany. Hamburg and Bremen are "Free and Hanseatic Cities". Generally, the city-states have no other rights or duties than the other states. Through the financial redistribution system of Equalization Payments in Germany (German: Länderfinanzausgleich), they do receive more money because of their demographic characteristics. The city-states are most distinctive due to the names of their state organs: their governments are called Senate, the prime ministers 'mayor' (Governing Mayor in Berlin and First Mayor in Hamburg) or President of the Senate (in Bremen) and also the expressions for their state parliaments differ from the other states. In the 18th century, many German cities were free imperial cities (German: Reichsstädte), without a principality between them and the imperial level. After the Napoleonic era, in 1815, four were still city-states: Hamburg, Bremen and Lübeck in Northern Germany, and Frankfurt where the Federal Convention was located. Frankfurt was incorporated by Prussia in 1866, and Lübeck became a part of Prussia during the national socialist regime in 1937 (Greater Hamburg Law). After 1945, Berlin was a divided city, and the Western part became a German quasi-state under (Western) Allied supervision. Since 1990/1991, the reunited Berlin is an ordinary German state among others. Hungary In Hungary, 23 of the cities are "cities with county rights". These cities have equal rights with the 19 counties of Hungary. Budapest, the capital city is also a special district, outside of the country's system of counties. Although Budapest does not belong to Pest County which surrounds it, it is still the county headquarters. Ireland
