The state of Ohio is located in the Midwestern United States, more precisely it is the easternmost state that is still included in this region. Ohio borders Pennsylvania to the east, West Virginia to the southeast, Kentucky to the southwest, Indiana to the west, and Michigan to the northwest. Furthermore, Ohio is bordered in the north by Lake Erie and thus also borders on Canada and the Canadian province of Ontario. The name of the state is derived from the Iroquois language and means “great river”. The state’s official nickname is “Buckeye State”, after the Ohio Buckeye tree. Ohio has other nicknames such as “The Mother of Presidents”, “Birthplace of Aviation” and “The Heart of It All”. The official state motto of Ohio is “With God, all things are possible” and comes from the Gospel according to Matthew (chapter 19, verse 26: “Jesus looked at them and said to them: It is impossible for people, but for God everything is possible. “).

The state of Ohio covers an area of ​​approximately 116,096 km² – with around 11.5 million inhabitants. The capital and largest city in Ohio is Columbus with approximately 787,000 inhabitants. Ohio joined the Union on March 1, 1803, as the 17th state. The state of Ohio’s economy is very diverse. Ohio is one of the leading states in the fields of mechanical engineering and the tool industry. However, agriculture also plays an important role in the state’s economy. Ohio belongs to the so-called “Corn Belt”, a region in the Midwest that mainly cultivates corn. In addition, the states of Iowa, Indiana and Illinois belong to the “Corn Belt” and alone account for approximately 50 percent of all corn cultivation in the United States. Smaller parts of the states of Kansas, Kentucky, Michigan, Minnesota, Missouri, Nebraska, South Dakota and Wisconsin also belong to the “Corn Belt”.

The landscape of Ohio is flat in the northwestern part of the state and rises to the southwest and southeast and becomes more hilly because the Appalachian Mountains and the Allegheny Mountains begin here. Ohio has over 2,500 lakes and more than 72,000 km of rivers. Ohio is popular with tourists because of its varied landscape and its many historic sites. Furthermore, in the north of the state on the coast to Lake Erie or on the offshore islands you can almost spend a real beach holiday, but the state’s amusement parks are also very popular, for example the famous park “Cedar Point” in Sandusky. Ohio is ideal for tourists because it is a good opportunity to get to know many impressions of American culture.

Famous sons and daughters of the state are the Afro-American Nobel laureate in literature Toni Morrison, the famous inventor, not only of the incandescent lamp, as well as Thomas Alva Edison, the flight pioneers Wright and Neil Armstrong, the first to be the first man on the moon. The state’s nickname “Birthplace of Aviation” is derived from the latter. The actor Clark Gable, the director Steven Spielberg and a total of 7 US presidents also come from Ohio.
This fact should also explain the nickname “The Mother of Presidents”.

The seven U.S. Presidents born in Ohio are James A. Garfield, Ulysses S. Grant, Warren G. Harding, Benjamin Harrison, Rutherford B. Hayes, William McKinley and William Howard Taft. Ohio’s role in “Electorial College” is also of political importance. The federal stat sends 18 electoral men and women to the “Electorial College”, which ultimately elects the president after the nationwide presidential election. Ohio is also considered a “swingstate”, in which the Democrats and the Republicans sometimes have the majority and is therefore particularly competitive before the presidential election. Between July 18 and 21, “The Q”, the home stadium of the Cleveland Cavaliers NBA team, hosted the Republicans’ nomination party convention in Cleveland. Donald Trump was elected candidate for the presidential election on November 8, 2016 with 69.8% of the vote.

Before the European settlement, today’s Ohio was part of the eastern Mississippi culture and was, among other things, by the tribes of the Miami, the Wyandot, the Shawnee, the Lenni Lenape, the Ottawa and the Erie. Due to the pressure of European colonization, the Iroquois, who previously settled in what is now the state of New York, later claimed parts of the Ohio area. The first Europeans to “engage” in this area were the French, who established a system of trading posts here in the 18th century. However, these “activities” led to the French and Indian War of 1754.

Since 1787, the area of ​​what is now Ohio has been developed as a northwest territory, but the northwest territory also included today’s states of Indiana, Illinois, Michigan, Wisconsin and the part of Minnesota that lies east of the Mississippi. Parts of the northwestern territory were able to become states when their population reached 60,000. Ohio became the 17th state to join the Union on March 1, 1803, although it had less than 60,000 residents at the time. The first capital of Ohio was Chillicothe until 1810, then Zanesville and then Columbus since 1816.

Cities and towns

With a population of approximately 200,000, Akron is the fifth largest city in Ohio. The city is located in the northeast of on the banks of the Cuyahoga River. Akron was founded in 1825. The city is named after the Greek word ἄκρος, which in this context means “highest point” because Akron is at the highest point of the Ohio-Erie Canal.

Akron used to be an industrial city and was called Rubber Capital of the World, but Akron was also affected by the structural change in the region and is now known as the City of Invention. Last but not least, because a scientific location has been established here with the University of Akron and other research institutions. The Organization of Alcoholics Anonymous was founded in Akron in 1935. Akron has a lot to offer culturally interested visitors with the Akron Art Museum and the EJ Thomas Performing Arts Hall.

The Blossom Music Center and Mary Campbell Cave are also located in the suburb of Cuyahoga Falls. Akron also runs the Cuyahoga Valley Scenic Railroad that runs through the Cuyahoga Valley National Park. Akron is twinned with Chemnitz (Germany).

Columbus is the capital of Ohio and is centrally located in the interior of the state at the confluence of the Scioto River and Olentangy River. Columbus has approximately 787,000 residents, making it the largest city in Ohio. In fact, 1.86 million people live in the city’s metropolitan area. Columbus is named after the Italian explorer Christopher Columbus. Columbus was founded in 1812 because, after joining the Union, it wanted a central capital as a separate state. Columbus has also officially been the state capital of Ohio since 1816. Columbus is home to Ohio State University, the largest university in the state with approximately 57,000 students, approximately 3 km north of the center. Ohio State University also has the largest contiguous campus of any US university.

The campus and 57,000 students also shape the cityscape. Because of its function as the capital and the University of Columbus, it is an important location for research. Furthermore, the historic district German Village, a district built in the 19th century by German immigrants, is extremely interesting. Columbus used to be in the Manufacturing Belt, or now in the Rust Belt. Has largely recovered from the decline since the 1970s. In Columbus there are also some interesting buildings such as the State Capitol or the LeVeque Tower. Those looking for culture will be impressed by the Wexner Center for the Arts or the Columbus Museum of Art, for example.
Columbus has been twinned with Dresden since 1992 (Germany).

The city is located in northern Ohio on the shores of Lake Erie. With a population of approximately 395,000, Cleveland is the second largest city in Ohio after Columbus. The city’s metropolitan area, also known as Greater Cleveland, is home to 2.07 million people, which is the second largest metropolitan area in Ohio. The city is the urban center of northeast Ohio. In former times the former industrial city was much larger, so up to 900,000 inhabitants lived here in the 1930s, when the city was an important transport hub.

Cleveland was founded in 1796 during the land survey of the region by Moses Cleaveland, the founder and namesake of the city. Throughout history, Cleveland has grown to become the second largest automobile manufacturing location in the United States. However, the development to an industrial city had not only advantages, because the Cuyahoga River was so polluted in earlier times, especially by the city’s petrochemical industry, that its surface was combustible.

The decline of the steel and automotive industries, which transformed the formerly prospering “Manufacturing Belt” into the “Rust Belt”, did not leave Cleveland unscathed, but the city has been on the upswing again since the 1980s. Nowadays the city is a “service city”, which due to the successful modernization measures deserves the title “Comeback City” very much. Cleveland now offers some treasures for visitors.

The Cleveland Orchestra, for example, is one of the best symphony orchestras in the USA, which is counted among the “Big Five”, in the city. Cleveland also has world-class museums, such as the Cleveland Museum of Art and the Museum of Contemporary Art Cleveland. The Playhouse Square Center is also the second largest performing arts center in the United States in Cleveland. For nature lovers, Cleveland, whose nickname is “Forest City”, is also ideal because of its proximity to the Cuyahoga Valley National Park. This national park, the only one in Ohio, is located just south of the city.

The paths to the beaches on the shores of Lake Erie are also very short. Cleveland’s best-known personalities include industrialist John D. Rockefeller and the band Nine Inch Nails. Cleveland maintains city partnerships with Bratislava (Slovakia), Gdansk (Poland), Heidenheim an der Brenz (Germany), Lima (Peru), Ljubljana (Slovenia), Taipei (Taiwan) and Volgograd (Russia).

The city of Cincinnati is located in the extreme southwest of Ohio on the north bank of the Ohio River and thus directly on the border with the state of Kentucky. Cincinnati has approximately 297,000, making it the third largest city in Ohio after Columbus and Cleveland. The city’s metropolitan area is home to 2.13 million people, the largest metropolitan area in Ohio. However, it should be noted that this metropolitan area also extends into the neighboring states of Indiana and Kentucky. Cincinnati is one of the most important cities in the region and is nicknamed “The Queen City”.

Cincinnati was founded in 1788 as one of the first settlements in what was then the Northwest Territory. The name Cincinnati comes from the Roman consul and dictator “Lucius Quinctius Cincinnatus”. During the Civil War, Cincinnati was an important port of call for “fleeing slaves” from the south. The development of the city received a significant boost through the opening of the Miami Erie Canal and thus the connection to the Great Lakes. Cincinnati was also an important point of contact for German immigrants and it can be assumed that at the beginning of the 20th century, about 60% of the urban population was of German descent. This is still noticeable today because Cincinnati is home to the largest Oktoberfest in the United States.

This is also reflected in the cityscape, because in the northern district of Over-the-Rhine there are a large number of buildings in the historicist Italianate architectural style, similar to New York City, Munich or Vienna. In addition to this historic district, Cincinnati has of course more to offer. The downtown area is centered around Fountain Square with Tyler Davidson Fountain. The Carew Tower is a symbol of the city and significantly shapes the skyline. With the Cincinnati Symphony Orchestra, the Cincinnati Opera and the Cincinnati Ballet, visitors to the city who are interested in music are also well catered for.
Cincinnati has been twinned with Munich (Germany) and therefore the existence of a Hofbräuhaus in Cincinnati is not surprising.

Dayton is located in Montgomery County and has a population of around 140,500. The location became world-famous for the conference that took place between November 1 and November 21, 1995 at Wright-Patterson Air Force Base near Dayton to end the Yugoslav war. The conference table included the Serbian President Slobodan Milošević (1941-2006), the Croatian President Franjo Tuđman (1922-1999), the President of the State Presidency of Bosnia and Herzegovina Alija Izetbegović (1925-2003) and the American chief negotiator Richard Holbrooke (1941- 2010). The document, signed in Paris on December 14, went down in history as the Dayton Agreement.

It is also worth mentioning that the Wright brothers built the first aircraft in their bicycle factory that was heavier than air (i.e. not a Zeppelin) and was piloted by a pilot. It had made its maiden flight on December 17, 1903 in Kitty Hawk, North Carolina. In the following years they had further developed and improved their aircraft here. But the city is now particularly notorious for the numerous local opioid addicts who are legally prescribed their drugs in the form of fentanyl or oxycodone as pain relievers. The scale of this drug addiction has now led to a national emergency in much of the United States.

The city of Toledo has approximately 287,000 residents and is located in the far northwest of Ohio on the shores of Lake Erie in close proximity to the border with the state of Michigan. This makes Toledo the fourth largest city in Ohio and over 650,000 people live in the city’s metropolitan area. The city of Toledo was founded twice, once in 1833 and again in 1837 after the Toledo War ended. Visitors to the city will be particularly pleased with the Toledo Museum of Art, which is internationally known, and the Collingwood Arts Center.

Toledo also offers an excellent zoo, the over 200,000 m² Toledo Botanical Garden and a generally very attractive art and culture scene. The Rosary Cathedral in Toledo is also a very attractive cathedral. Toledo should also be interesting for visitors who are drawn to the beaches of Lake Erie due to its proximity to it.
