Belgrade vs Pittsburgh

Informations

Belgrade ( BEL-grayd; Serbian: Београд, romanized: Beograd, lit. 'White City', pronounced [beǒɡrad] (listen); names in other languages) is the capital and largest city of Serbia. It's located at the confluence of the Sava and Danube rivers as well as the crossroads of the Pannonian Plain and the Balkan Peninsula. Nearly 1.7 million people live within the administrative limits of the Town of Belgrade, a quarter of the total population of Serbia.Belgrade is among the oldest continuously inhabited cities in Europe and the World. One of the most important prehistoric cultures of Europe, the Vinča culture, evolved within the Belgrade area in the 6th millennium BC. In antiquity, Thraco-Dacians inhabited the region and, after 279 BC, Celts settled the town, naming it Singidūn. It was conquered by the Romans under the reign of Augustus and given Roman town rights in the mid-2nd century. It had been settled by the Slavs in the 520s, and changed hands several times between the Byzantine Empire, the Frankish Empire, the Bulgarian Empire, and the Kingdom of Hungary before it became the seat of the Serbian king Stefan Dragutin in 1284. Belgrade served as capital of the Serbian Despotate during the reign of Stefan Lazarević, and then his successor Đurađ Branković returned into the Hungarian king in 1427. Noon bells in support of the Hungarian army against the Ottoman Empire during the siege in 1456 have remained a widespread church heritage to this day. In 1521, Belgrade was conquered by the Ottomans and became the chair of the Sanjak of Smederevo. It often passed from Ottoman to Habsburg rule, which saw the destruction of most of the city during the Austro-Ottoman wars.

In the period after the Serbian Revolution, Belgrade was named the capital of Serbia in 1841. Northern Belgrade stayed the southernmost Habsburg post until 1918, when it was attached to the city, because of former Austro-Hungarian lands becoming the role of the new Kingdom of Serbs, Croats and Slovenes after World War I. Belgrade was the capital of Yugoslavia from its creation in 1918 to its dissolution in 2006. In a fatally strategic position, the city was battled over in 115 wars and razed 44 times, being bombed five times and surrounded many times.Being Serbia's primate city, Belgrade has special administrative status within Serbia. It's the seat of the central authorities, administrative bodies, and government ministries, as well as home of almost all the largest Serbian companies, media, and scientific associations. Belgrade is categorized as a Beta-Global City. The town is home to the Clinical Centre of Serbia, one of the hospital complexes with the biggest capacity in the world, the Church of Saint Sava, one of the biggest Orthodox church buildings, and the Štark Arena, one of those indoor arenas with the biggest capacity in Europe. Belgrade hosted major international events like the Danube River Conference of 1948, the first Non-Aligned Movement Summit (1961), the first major gathering of the OSCE (1977--1978), Eurovision Song Contest (2008), as well as sports events like the first FINA World Aquatics Championships (1973), UEFA Euro (1976), Summer Universiade (2009) and EuroBasket three-times (1961, 1975, 2005).

Pittsburgh ( PITS-burg) is a city in the state of Pennsylvania in the United States, and is the county seat of Allegheny County. A population of about 300,286 (2019) residents live within the city limits, making it the 66th-largest city in the U.S. and the second-most populous city in Pennsylvania behind Philadelphia. The Pittsburgh metropolitan area is the anchor of Western Pennsylvania; its population of 2,324,743 is the largest in both the Ohio Valley and Appalachia, the second-largest in Pennsylvania, and the 27th-largest in the U.S. Pittsburgh is located in the southwest of the state, at the confluence of the Allegheny River and the Monongahela River, forming the Ohio River. Pittsburgh is known both as "the Steel City" for its more than 300 steel-related businesses and as the "City of Bridges" for its 446 bridges. The city features 30 skyscrapers, two inclined railways, a pre-revolutionary fortification and the Point State Park at the confluence of the rivers. The city developed as a vital link of the Atlantic coast and Midwest, as the mineral-rich Allegheny Mountains made the area coveted by the French and British empires, Virginians, Whiskey Rebels, and Civil War raiders.Aside from steel, Pittsburgh has led in the manufacturing of other important materials — aluminum and glass — and in the petroleum industry. Additionally, it is a leader in computing, electronics, and the automotive industry. For part of the 20th century, Pittsburgh was behind only New York City and Chicago in corporate headquarters employment; it had the most U.S. stockholders per capita. Deindustrialization in the 1970s and 80s laid off area blue-collar workers as steel and other heavy industries declined, and thousands of downtown white-collar workers also lost jobs when several Pittsburgh-based companies moved out.

The population dropped from a peak of 675,000 in 1950 to 370,000 in 1990. However, this rich industrial history left the area with renowned museums, medical centers, parks, research centers, and a diverse cultural district.After the deindustrialization of the mid-20th century, Pittsburgh has transformed into a hub for the health care, education, and technology industries. Pittsburgh is a leader in the health care sector as the home to large medical providers such as University of Pittsburgh Medical Center (UPMC). The area is home to 68 colleges and universities, including research and development leaders Carnegie Mellon University and the University of Pittsburgh. Google, Apple Inc., Bosch, Facebook, Uber, Nokia, Autodesk, Amazon, Microsoft and IBM are among 1,600 technology firms generating $20.7 billion in annual Pittsburgh payrolls. The area has served as the long-time federal agency headquarters for cyber defense, software engineering, robotics, energy research and the nuclear navy. The nation's eighth-largest bank, eight Fortune 500 companies, and six of the top 300 U.S. law firms make their global headquarters in the area, while RAND Corporation (RAND), BNY Mellon, Nova, FedEx, Bayer, and the National Institute for Occupational Safety and Health (NIOSH) have regional bases that helped Pittsburgh become the sixth-best area for U.S. job growth.In 2015, Pittsburgh was listed among the "eleven most livable cities in the world"; The Economist's Global Liveability Ranking placed Pittsburgh as the most or second-most livable city in the United States in 2005, 2009, 2011, 2012 and 2014. The region is a hub for Leadership in Energy and Environmental Design and energy extraction.
