Independence Day in Croatia is celebrated on October 8th each year, marking the decision made by the Croatian Parliament, or Sabor, in 1991 to sever constitutional ties with Yugoslavia. The decision came after months of rising tension and warfare, characteristic of the Croatian War of Independence. This was a monumental decision that has shaped the direction of the nation ever since.

It wasn't until three years later after the announcement that Croatia was able to fully function as an independent nation due to ongoing battles and conflicts. But eventually, the cessation of war allowed Croatia to begin operating as the Republic of Croatia, stepping away from a socialist federal unit to a democratic republic. The capital city, Zagreb, is often the heart of the celebrations with a variety of events taking place to commemorate the holiday.

Croatia's Independence Day is a public holiday and is often celebrated with parades, fireworks, concerts, and other cultural and sporting events. This day promotes patriotic sentiments among the population and serves as a reminder of the struggles Croatia overcame to establish its sovereignty. Despite the historical importance of this day, it is notable that in recent years some actions have been made to change the date of celebration to another significant day from Croatian history, but currently, October 8 still stands as the official date.
