The Arrow Cross Party was a group of very mean and bad people in Hungary a long time ago. They believed that some people were better than others and that they should be treated badly. They had a symbol that looked like a cross with arrows pointing in different directions. This symbol was put on everything they owned or on things they made.
These people did bad things, like hurting other people who didn't agree with them and making unfair rules that only helped them. They also made a lot of rules that were not good and made life very hard for many people who lived in Hungary.
The Arrow Cross Party leaders were very powerful and they thought they were right even when they were very very wrong. They made people follow their rules and did not care about how they felt or what they wanted.
Thankfully, some good people were able to stop the Arrow Cross Party from doing any more bad things. Many people fought against them and eventually they were defeated. The Arrow Cross Party is now just a bad memory that we can learn from and make sure that we never let any group of people treat others unfairly like they did.
