A Nation’s Love Affair with the Croatian Language
Celebrated Every Year on 21st February | Dan Materinskog Jezika
Every year on 21st February, Croatia joins more than 100 countries around the world in marking International Mother Language Day, a UNESCO initiative launched in 1999 to promote linguistic diversity, multilingualism, and the protection of endangered languages. In Croatia, however, the occasion takes on a particularly intimate meaning. Observed as Dan materinskog jezika, it is not just a global awareness day but a deeply national celebration of the Croatian language itself, its history, its resilience, and the singular role it has played in forging a distinct national identity across centuries of foreign rule, political upheaval, and cultural struggle.
The UNESCO Roots of the Day
International Mother Language Day was proclaimed by UNESCO on 17th November 1999 and has been observed globally since 21st February 2000. The date was chosen to commemorate a tragic event in Bangladesh: on 21st February 1952, students at the University of Dhaka were shot and killed by Pakistani police as they demonstrated for the right to use their native Bengali language. The Language Movement, as it became known, eventually led to the recognition of Bengali as an official language of then-East Pakistan, and the sacrifice of those students became a symbol of the universal human attachment to one’s mother tongue.
UNESCO’s goal with the day is broad: to raise awareness of the world’s extraordinary linguistic richness, estimated at around 7,000 living languages, and to sound the alarm that at least 40 percent of these are endangered. Each year, the organisation selects a theme; recent themes have focused on the role of multilingual education in inclusive development, the preservation of indigenous languages, and the use of technology to safeguard linguistic heritage.
The Croatian Language: A History of Survival
To understand why Mother Tongue Day resonates so deeply in Croatia, one must understand what the Croatian language has been through. Croatian is a South Slavic language with roots stretching back to the medieval period. The earliest known document written in Croatian using the Glagolitic script, the Baška tablet, dates to around 1100 AD and is regarded as one of the most important artefacts in Croatian cultural history. Found on the island of Krk, the tablet records the donation of land by King Zvonimir and is celebrated as the birth certificate of written Croatian.
For much of its modern history, Croatian identity was threatened by the dominant political powers of the region. Under Habsburg rule, German and Latin were the languages of administration and prestige. During the 19th century Croatian National Revival, the Hrvatski narodni preporod, intellectuals, writers, and political activists fought fiercely to standardise the Croatian language, establish it in schools and government, and use it as the cornerstone of a national awakening. Figures such as Ljudevit Gaj, who reformed the Croatian alphabet in the 1830s, became heroes of this linguistic resistance.
The 20th century brought further trials. Under Yugoslav rule, particularly during the socialist era, Croatian was formally merged with Serbian into a single “Serbo-Croatian” language in a policy that many Croats experienced as cultural suppression. The Croatian Spring of 1971, in which intellectuals and students openly demanded recognition of the Croatian language and greater political autonomy, was brutally suppressed by the Tito government. It was not until Croatian independence in 1991 that Croatian was formally enshrined as the sole official language of the new republic.
How Croatia Marks the Day
In Croatia, Mother Tongue Day is observed with a blend of educational, cultural, and civic activities. Events typically include:
- School programmes and classroom activities in which students explore the history of the Croatian language, learn about endangered languages around the world, and reflect on their own linguistic identity. Children are often asked to write poetry or short essays about what their mother tongue means to them.
- Public lectures and academic symposia hosted by universities, cultural institutions, and linguistic societies. The Croatian Language Institute (Institut za hrvatski jezik i jezikoslovlje) often plays a leading role in organising events that address questions of language policy, standardisation, and the challenges of the digital age.
- Literary readings and theatre performances celebrating the richness of Croatian literature, from medieval Glagolitic texts to the poetry of the Renaissance Dalmatian coast, the 19th-century National Revival, and contemporary Croatian writing.
- Media features and broadcasts in which journalists, scholars, and cultural figures discuss the state of the Croatian language, common errors, new words entering everyday use, and the influence of English on contemporary Croatian speech.
- Community events celebrating Croatia’s regional linguistic diversity, including the dialects of Kajkavian, Čakavian, and Štokavian, the three distinct dialect groups that together form the Croatian linguistic tradition.
The Three Dialects: Croatia’s Internal Linguistic Richness
One of the most fascinating dimensions of the Croatian language, and one that Mother Tongue Day often highlights, is its extraordinary internal diversity. Croatian is traditionally divided into three major dialect groups, named after their respective words for the pronoun “what”:
Štokavian — the basis of the standard Croatian language, spoken across most of Croatia, Bosnia and Herzegovina, Serbia, and Montenegro. It takes its name from the word što (what).
Čakavian — spoken primarily along the Dalmatian coast, on the islands, and in Istria. Named after the word ča (what), Čakavian is considered by linguists to be the most archaic of the three dialects, preserving features of Old Croatian that have disappeared elsewhere. It has a rich literary tradition dating back to medieval times.
Kajkavian — spoken in northern Croatia, including Zagreb and its surrounding region. Named after the word kaj (what), Kajkavian is closely related to Slovenian and has its own distinct literary and folk tradition. The poet Antun Gustav Matoš wrote lovingly of the Kajkavian heartland, and the dialect remains a cherished marker of Zagreb identity.
This tripartite structure makes Croatian linguistically unique in Europe, a standard language that sits alongside and encompasses three distinct dialect traditions, each with its own literature, folklore, and cultural heritage. On Mother Tongue Day, this diversity is celebrated rather than obscured.
Language in the Digital Age
In recent years, Mother Tongue Day in Croatia has increasingly focused on the challenges posed by the digital revolution. The dominance of English in global technology, social media, and online culture has led to widespread borrowing, code-switching, and linguistic change, processes that accelerate especially among young people. Croatian linguists and educators debate questions that will be familiar to many small-language communities: how to adapt new vocabulary in ways that honour the logic of the Croatian language rather than simply importing English terms wholesale; how to ensure that Croatian remains a full-function language in the age of artificial intelligence and machine translation; and how to make Croatian digital content rich enough to compete for the attention of younger generations.
Croatia’s accession to the European Union in 2013 added another dimension to these conversations. Croatian became one of the EU’s 24 official languages, giving it considerable institutional protection and prestige. EU membership brought new investment in Croatian-language translation, interpretation, and documentation services, as well as new pressures from the multilingual environment of Brussels and Strasbourg.
A Language as a Living Identity
Perhaps what makes Croatia’s engagement with Mother Tongue Day so genuine is that language, for Croats, has never been merely a tool of communication. It has been a battlefield, a refuge, a declaration of selfhood. When Croatian writers of the Renaissance, Marko Marulić, Petar Hektorović, Hanibal Lucić, chose to write in Croatian rather than Latin at a time when Latin was the prestige language of European learning, they were making a political statement as much as a literary one. When the linguists of the 19th-century National Revival standardised Croatian orthography and grammar, they were not simply tidying up a writing system, they were building a nation.
This weight of history means that on 21st February, when Croatian schoolchildren read poems about their language, when professors give public lectures on the beauty of Čakavian verse, and when ordinary people pause to reflect on the words they have inherited, they are participating in something far larger than a UNESCO calendar event. They are reaffirming a connection to a language that their ancestors fought, and sometimes died, to preserve.
Words Worth Keeping
Mother Tongue Day is a reminder that every language is irreplaceable, a unique way of naming the world, of expressing love and grief and wonder, of carrying within its grammar and idioms the entire lived experience of a people. For Croatia, with its centuries of linguistic struggle and its astonishing internal diversity, the day is an occasion for genuine pride and genuine vigilance.
The Croatian word for homeland is domovina. The word for mother tongue is materinski jezik. In Croatia, both are understood to be the same thing, home.
