Tomislav’s tenth-century kingdom still anchors Adriatic Croatia
Croatia fronts the Adriatic between Central and Southeastern Europe, bordering Slovenia, Hungary, Serbia, Bosnia and Herzegovina, Montenegro, and Italy at sea. Croats entered Roman Illyria in the sixth century; Duke Branimir won recognition in 878 and King Tomislav raised a kingdom in 925 before later unions and modern republic institutions.
More than 1,000 islands and islets make up the Croatian archipelago, the largest on the Adriatic. Zagreb is the capital and main cultural and economic hub, followed by Split, Rijeka and Osijek. Twenty counties grouped in four regions cover 56,594 square kilometres, and the population stood at nearly 3.9 million in 2026.
The early Croats settled as two duchies about a century after arriving. When the Trpimirović line ran into a succession crisis, the crown passed into personal union with Hungary in 1102. Facing the Ottomans, Croatia sided with the Habsburgs in 1527. In 1918 it went through the short-lived State of Slovenes, Croats and Serbs into the Kingdom of Yugoslavia. Axis powers occupied most of it in the Second World War and set up the puppet Independent State of Croatia, while resistance forces founded the Socialist Republic of Croatia inside federal Yugoslavia in 1943. Independence was declared in 1991.
Today the country is a parliamentary democracy with a prime minister, a president and a single-chamber legislature, and several parties compete. It belongs to the European Union, NATO, the UN and the WTO, held a non-permanent Security Council seat in 2008 and 2009, and has sent troops on peacekeeping and other missions abroad since 1999. The high-income economy rests on services, industry and farming, with tourism especially important. Croatia has invested heavily in transport along European corridors and in liquefied natural gas, geothermal power and electric transport.
The name goes back through Medieval Latin Croātia and Slavic forms to a third-century word, Khoroáthos, on the Tanais Tablets. Its most likely root is an Alanian or Proto-Ossetian term meaning guardian or protector.
