Okay kiddo, so do you remember when you were playing with your toy money and you ran out of it? You probably felt sad and didn't know what to do. Well, something similar happened in Spain a while ago, but instead of toy money, it was real money that people and businesses didn't have enough of.
In 2008, there was a big problem with banks and other companies in Spain that had borrowed a lot of money to buy houses and build things. They couldn't pay back all the money they owed, and it caused a big problem called a financial crisis. Lots of people lost their jobs and homes, and it was really hard for them.
The crisis lasted for several years, until 2014, because it was difficult for the government to fix the problem. They had to make hard decisions about how to spend their money and help the people who were struggling. They also had to work with other countries and organizations to try to fix the problem together.
But finally, things started to get better, and Spain's economy started to grow again. It was a tough time for everyone, but they learned from it and made changes to try to prevent it from happening again in the future.
