Zagreb’s known history begins in medieval times with two hills: Kaptol, now the site of Zagreb’s cathedral, and Gradec. When the two settlements merged in 1850, Zagreb was officially born.

The space now known as Trg Bana Jelačića became the site of Zagreb’s lucrative trade fairs, spurring construction around its edges. In the 19th century the economy expanded with the development of a prosperous clothing trade and a rail link connecting Zagreb with Vienna and Budapest. The city’s cultural life blossomed, too.

Zagreb also became the centre for the Illyrian movement. Count Janko Drašković, lord of Trakošćan Castle, published a manifesto in Illyrian in 1832 and his call for a national revival resounded throughout Croatia. Drašković’s dream came to fruition when Croatia and its capital joined the Kingdom of Serbs, Croats and Slovenes after WWI.

Between the two world wars, working-class neighbourhoods emerged in Zagreb between the railway and the Sava River, and new residential quarters were built on the southern slopes of Mt Medvednica. In April 1941 the Germans invaded Yugoslavia and entered Zagreb without resistance. Ante Pavelić and the Ustaše moved quickly to proclaim the establishment of the Independent State of Croatia (Nezavisna Država Hrvatska), with Zagreb as its capital. Although Pavelić ran his fascist state from Zagreb until 1944, he never enjoyed a great deal of support within the capital, which maintained support for Tito’s Partisans.

In postwar Yugoslavia, Zagreb (to its chagrin) took second place to Belgrade but continued to expand. Zagreb was made the capital of Croatia in 1991, the same year that the country became independent.
