⭐ Core Definition: Graz

Graz (German: [ɡraːts] ) is the capital of the Austrian state of Styria and the second-largest city in Austria, after Vienna. On 1 January 2025, Graz had a population of 306,068 (343,461 including secondary residence). In 2023, the population of the Graz functional urban area (FUA) stood at 660,238. Graz is known as a city of higher education, with four colleges and four universities. Combined, the city is home to more than 63,000 students. Its historic centre (Altstadt) is one of the best-preserved city centres in Central Europe.

The earliest documented mention of Graz dates to the 12th century, when it emerged as a fortified settlement under the rule of the Babenbergs. During the Late Middle Ages, the city developed into an important commercial and administrative center and, from the 14th century onward, served as the residence of the Inner Austrian branch of the Habsburg dynasty. This period was marked by significant cultural and architectural growth, with Renaissance and Baroque buildings shaping the historic city center. Graz also functioned as a strategic military stronghold against the Ottoman Empire, reflected in the fortifications constructed on the Schlossberg. In the 19th and 20th centuries, industrialization and subsequent modernization established Graz as a major urban and educational center, a role it continues to hold in contemporary Austria.

👉 Graz in the context of Johannes Kepler

Johannes Kepler (27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, natural philosopher and writer on music. He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books Astronomia nova, Harmonice Mundi, and Epitome Astronomiae Copernicanae. The variety and impact of his work made Kepler one of the founders and fathers of modern astronomy, the scientific method, natural science, and modern science. He has been described as the "father of science fiction" for his novel Somnium.

Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe in Prague, and eventually the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He also taught mathematics in Linz, and was an adviser to General Wallenstein.

Graz in the context of Iron Cross

The Iron Cross (German: Eisernes Kreuz, listen, abbreviated EK) was a military decoration in the Kingdom of Prussia, the German Empire (1871–1918), and Nazi Germany (1933–1945). The design, a black cross pattée with a white or silver outline, was derived from the insignia of the medieval Teutonic Order and borne by its knights from the 13th century. As well as being a military medal, it has also been used as an emblem by the Prussian Army, the Imperial German Army, and the Reichswehr of the Weimar Republic, while the Balkenkreuz (bar cross) variant was used by the Wehrmacht. The Iron Cross is now the emblem of the Bundeswehr, the modern German armed forces.

King Frederick William III of Prussia established the Iron Cross award on 17 March 1813 during the Napoleonic Wars (EK 1813). The award was backdated to the birthday (10 March) of his late wife, Queen Louise, who was the first person to receive it (posthumously). The Iron Cross was also awarded during the Franco-Prussian War (EK 1870), World War I (EK 1914), and World War II (EK 1939). During World War II, the Nazi regime made their own version by superimposing a swastika on the medal. The Iron Cross was usually a military decoration only, though some were awarded to civilians for performing military roles, including Hanna Reitsch and Melitta Schenk Gräfin von Stauffenberg for being civilian test pilots during World War II.

Graz in the context of Heinrich Ignaz Franz Biber

Heinrich Ignaz Franz von Biber (correctly Biber von Bibern; bapt. 12 August 1644 – 3 May 1704) was a Czech-Austrian composer and violinist. Biber worked in Graz and Kroměříž before he illegally left his employer, Prince-Bishop Karl Liechtenstein-Kastelkorn, and settled in Salzburg. He remained there for the rest of his life, publishing much of his music but apparently seldom, if ever, giving concert tours.

Biber was among the major composers for the violin in the history of the instrument. His own technique allowed him to easily reach the 6th and 7th positions, employ multiple stops in intricate polyphonic passages, and explore the various possibilities of scordatura tuning. Among other pieces, Biber wrote operas, sacred music and music for chamber ensemble. He also wrote one of the earliest known pieces for solo violin, the monumental passacaglia of the Mystery Sonatas.
