Carantania and the Slavic Settlement of the Eastern Alps
Slavic peoples settled the eastern Alps and organised Carantania, an early principality whose dukes were enthroned in the Slovene tongue before Frankish power absorbed the region.
The lands of present-day Slovenia lie where the Alps meet the Pannonian plain and the head of the Adriatic, a crossroads settled in turn by Illyrians, Celts who founded the kingdom of Noricum, and Romans, whose colony of Emona stood on the site of modern Ljubljana. As Roman order collapsed, Slavic peoples migrated into the eastern Alpine valleys during the sixth and seventh centuries, becoming the ancestors of the Slovenes and laying down the linguistic and territorial foundation of all later Slovene history.
Out of this settlement emerged Carantania (Karantanija), a Slavic principality whose heartland lay to the north of today's Slovenia, around Klagenfurt in present-day Austrian Carinthia. Pressed by the Avars, the Carantanians allied with neighbouring Bavaria in the eighth century and were drawn into the orbit of the Frankish realm, which brought them under Christian and Frankish overlordship. Carantania is remembered above all for the ancient ritual installation of its dukes, performed in the Slovene language at the Prince's Stone near Krnski grad, a ceremony so distinctive that it endured in altered form into the late Middle Ages.
By the close of the first millennium the eastern Alpine Slavs had been incorporated into the Frankish and then the Holy Roman Empire, and the principality of Carniola is first attested in the late tenth century as a frontier march to the south. Christianisation and the arrival of German and Frankish lords reshaped the region's institutions, yet the Slavic population persisted, and the memory of Carantania and its enthronement rite would later be invoked as evidence of an ancient Slovene political tradition.
“The dukes of Carantania were enthroned in the Slovene language at the Prince's Stone, a ritual unique in medieval Europe.”

The Habsburg Duchies and the Birth of Written Slovene
Gathered into the Habsburg duchies of Carniola, Styria and Carinthia, the Slovene lands endured six centuries of Austrian rule, in which the Reformation gave them their first books and a literary language.
Through the high Middle Ages the Slovene-speaking lands were organised into the duchies of Carniola, Styria and Carinthia, ruled by a succession of German and Frankish noble houses. In 1335 Carinthia and Carniola passed into the hands of the Habsburgs, who already held Styria, binding almost all the Slovene lands to the dynasty that would govern them for some six hundred years. Carniola was raised to a duchy in 1364, and its capital, Ljubljana, known to its German rulers as Laibach, grew into the chief city of the Slovene lands. The powerful Counts of Celje rose to European prominence before their line died out in 1456, after which their estates too fell to the Habsburgs.
These centuries brought Ottoman raids, heavy feudal burdens and recurrent peasant uprisings, but also a decisive cultural turning point in the Protestant Reformation. In 1550 the Protestant preacher Primoz Trubar published a catechism and an alphabet primer, the Catechismus and Abecedarium, the first printed books in the Slovene language. Driven by the Reformation's conviction that people should read scripture in their own tongue, Trubar created a literary Slovene where none had existed in print; his work was continued by Jurij Dalmatin, who translated the whole Bible into Slovene in 1584, and Adam Bohoric, who produced the first Slovene grammar in the same year.
The Catholic Counter-Reformation that followed restored the old faith and suppressed Protestant worship, yet it could not erase the body of Slovene writing that had been created. The language survived in church and at home, and the printed word forged in the sixteenth century became the seed of a later national consciousness. Beneath the long surface of Habsburg rule, a distinct Slovene cultural identity had taken root that no dynasty could dissolve.
“In 1550 Primoz Trubar printed the first two books in Slovene, founding a literary language that the Counter-Reformation could suppress but never erase.”

The Illyrian Provinces and the National Awakening
Napoleon's Illyrian Provinces made Ljubljana a capital and stirred Slovene self-awareness; a nineteenth-century cultural awakening, led by the poet France Preseren, turned a literary identity into a political programme.
The Napoleonic wars briefly broke the rhythm of Austrian rule. Between 1809 and 1813 Napoleon detached the southern Slovene lands and neighbouring territories from Austria and organised them as the Illyrian Provinces, an autonomous unit of the French Empire with Ljubljana as its capital. French administration brought modernising reforms and, crucially for the Slovenes, gave their language a place in schooling and public life. Though Austria recovered the provinces after Napoleon's fall, confirmed by the Congress of Vienna in 1815, the episode planted the idea that the Slovenes were a people deserving of their own institutions.
The decades that followed saw a flowering of Slovene culture that historians call the national awakening. Its towering figure was the Romantic poet France Preseren, whose verse raised the vernacular to the level of high literature and gave the nation an enduring voice; his 1844 poem Zdravljica, a toast to the freedom and friendship of all peoples, would later furnish the words of the Slovene national anthem. Writers, scholars and clergy built a Slovene press, learned societies and a reading public, converting cultural pride into political ambition.
That ambition crystallised in the revolutionary year of 1848. During the Spring of Nations Slovene activists formulated the programme of a United Slovenia, demanding that all the Slovene-inhabited districts of the Habsburg monarchy be joined into a single autonomous unit, with the Slovene language recognised in administration and education. The programme was not achieved, but it marked the passage from cultural revival to modern national politics and remained the guiding aspiration of the Slovene movement down to the First World War.
“The United Slovenia programme of 1848 marked the transition from cultural initiatives to the modern political articulation of the Slovene nation.”

Into Yugoslavia: War, Partition and Contested Borders
The fall of Austria-Hungary drew the Slovenes into a Yugoslav state, but the new frontiers were bitterly contested: Carinthia voted to stay with Austria, Italy seized the western marches, and the Second World War tore the land into three occupation zones.
When Austria-Hungary collapsed at the end of the First World War, the Slovenes joined the other South Slavs of the former empire in the short-lived State of Slovenes, Croats and Serbs, proclaimed in October 1918. On 1 December 1918 this entity merged with the kingdom of Serbia to form the Kingdom of Serbs, Croats and Slovenes, renamed the Kingdom of Yugoslavia in 1929. For the first time the bulk of the Slovenes lived in a Slavic state of their own, though one in which power lay heavily with Belgrade.
The peace settlements left the Slovene nation divided by hotly disputed borders. To the north, the future of southern Carinthia was decided by plebiscite on 10 October 1920: in the contested basin, where many voters were Slovene-speaking, a majority of about 59 per cent chose to remain with the Republic of Austria, leaving a Slovene minority on the Austrian side of the frontier. To the west, under the Treaty of Rapallo of 1920 Italy acquired the Slovene Littoral, the Karst and parts of Inner Carniola, placing a large Slovene population under Italian rule and, after 1922, under Fascist policies of forced assimilation.
The Second World War brought catastrophe. In April 1941 the Axis powers invaded and dismembered Yugoslavia, partitioning the Slovene lands among Nazi Germany, which annexed the north, Fascist Italy, which took the centre and Ljubljana, and Hungary, which seized the Prekmurje region in the east. A Slovene Liberation Front was founded in Ljubljana on 26 April 1941 and joined Tito's Partisan movement; after years of occupation, resistance and bitter internal conflict, Slovene territory was liberated and the war ended in May 1945.
“In the Carinthian plebiscite of 10 October 1920 the contested basin voted, by about 59 per cent, to remain part of Austria.”

A European Republic and the Border Arbitration
Independent Slovenia anchored itself in NATO and the European Union, adopted the euro, and pursued a long-running maritime border dispute with Croatia to international arbitration.
Free of Yugoslavia, Slovenia built a parliamentary democracy and a market economy and turned decisively toward Western institutions. It joined the Council of Europe and the United Nations early in the decade, and its stable politics and relative prosperity smoothed a rapid integration into the Euro-Atlantic order. On 29 March 2004 Slovenia became a member of NATO, and on 1 May 2004 it joined the European Union in the bloc's largest single enlargement, the only former Yugoslav republic in that wave. On 1 January 2007 it became the first of the new member states to adopt the euro.
One legacy of the breakup of Yugoslavia, however, proved durable: the unresolved land and maritime border with neighbouring Croatia, centred on the Gulf of Piran (Piran Bay) at the head of the Adriatic, where the two republics' coasts meet and Slovenia's access to the open sea was at stake. After years of dispute the two countries signed an Arbitration Agreement on 4 November 2009 and submitted the question to the Permanent Court of Arbitration in The Hague. On 29 June 2017 the tribunal rendered its Final Award, determining the entire land boundary, drawing the maritime boundary through Piran Bay, and establishing a junction giving Slovenia access to the high seas through Croatian waters.
The award did not end the quarrel. Slovenia welcomed the decision as binding and historic, but Croatia, which had earlier withdrawn from the proceedings, rejected the ruling and declined to implement it; Slovenia later brought the matter before the European institutions. Within Europe, however, Slovenia had established itself as a small, settled and prosperous state, its identity rooted in the Slovene language first put into print nearly five centuries earlier and in the hard-won independence of 1991. Its natural and industrial heritage is recognised internationally, from the karst of the Skocjan Caves to the great mercury mine of Idrija, both inscribed on the UNESCO World Heritage list.
“On 29 June 2017 the Permanent Court of Arbitration fixed the boundary through Piran Bay and a junction to the high seas; Slovenia accepted it, Croatia rejected it.”

Chapter 05 · 1945 – 1991
Socialist Yugoslavia and the Road to Independence
As the most prosperous republic of socialist Yugoslavia, Slovenia settled its western border with Italy, then broke away in 1991 in the first secession from the Yugoslav federation, won in the Ten-Day War.
After 1945 Slovenia became one of the six federal republics of the Socialist Federal Republic of Yugoslavia under Josip Broz Tito. Its highly developed industry, education and proximity to Western Europe made it consistently the wealthiest and most productive of the Yugoslav republics, even as it chafed at the redistribution of its earnings to poorer regions. The post-war years also finally settled the western frontier: the contested Free Territory of Trieste was provisionally divided by the London Memorandum of 1954, which placed Zone A under Italian and Zone B under Yugoslav administration, and the arrangement was made permanent by the Treaty of Osimo, signed by Italy and Yugoslavia on 10 November 1975.
Tito's death in 1980 loosened the bonds of the federation, and through the 1980s Slovenia became the centre of demands for democratisation and greater autonomy. Civil society, independent media and an emerging political opposition pressed against the one-party system, while Slovene leaders resisted attempts to recentralise Yugoslavia under Serbian dominance. In a plebiscite held on 23 December 1990, with a turnout of 93.2 per cent, some 88.5 per cent of all eligible voters chose an independent Slovenia.
On 25 June 1991 the Slovenian parliament adopted the Basic Constitutional Charter on Sovereignty and Independence and a Declaration of Independence, making Slovenia, with Croatia, the first republic to leave Yugoslavia. The federal army moved to prevent the secession, triggering the Ten-Day War of 27 June to 7 July 1991, in which the lightly armed Slovene Territorial Defence fought the Yugoslav People's Army to a standstill. The European Community brokered the Brioni Declaration of 7 July 1991, which suspended the independence measures for three months and arranged the withdrawal of federal forces; Slovenia's independence soon became irreversible.
