Why do countries have national anthems and what is their origin?

A national anthem is like a song that tells a country’s story and makes people feel proud when they hear it.

Long ago, before there were songs, countries had flags and symbols to show who they were. But then came the idea of having a special song, one that could be sung together by lots of people, no matter where they were. This gave everyone something to share and celebrate, just like when you sing "Happy Birthday" with your friends.

At first, kings and queens used songs to announce their power or mark important events. Over time, these songs became more special, people started singing them at big moments, like when a country won a war or welcomed new leaders.

Today, national anthems are still used in big events, like the Olympics or when a country's flag is raised. They help everyone remember who they are and where they come from, just like how your favorite song makes you feel happy and connected to others.
