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.

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.

An ancient city with a long history, Cagliari has seen the rule of several civilisations. Under the buildings of the modern city there is a continuous stratification attesting to human settlement over the course of some five thousand years, from the Neolithic to today. Historical sites include the prehistoric Domus de Janas, partly damaged by cave activity, a large Carthaginian era necropolis, a Roman era amphitheatre, a Byzantine basilica, three Pisan-era towers and a strong system of fortification that made the town the core of Spanish Habsburg imperial power in the western Mediterranean Sea. Its natural resources have always been its sheltered harbour, the often powerfully fortified hill of Castel di Castro, the modern Casteddu, the salt from its lagoons, and, from the hinterland, wheat from the Campidano plain and silver and other ores from the Iglesiente mines.
