A spartakiad is like a huge sports festival where lots of people compete against each other. It's named after Spartacus, a famous leader who fought for freedom in ancient Rome. Just like him, people come together to compete and celebrate their strength and abilities. Think of it like a really big playground, with lots of different games and challenges for everyone to try. People train and practice to be their best, and they cheer each other on as they run, jump, throw, and play. Spartakiads can be organized for countries, regions or even schools, and they are a fun way for everyone to come together and show off their skills.
