The term "Greek State" refers to the modern nation-state of Greece, which emerged in the early 19th century after a successful war of independence against Ottoman Empire rule. Officially established in 1830, the Greek State has since developed a parliamentary democracy and a diverse economy, with tourism and shipping as key sectors. The Greek State is known for its rich cultural heritage, including contributions to philosophy, art, and politics. It is home to significant historical sites, such as the Acropolis in Athens, which reflect its ancient civilization. Today, Greece is a member of the European Union and plays an active role in regional and international affairs.
