Active citizenship and this promotion soon became the main objective of the educational systems and is gaining more and more importance in national curriculum across Europe. Citizenship education has a goal to active children to become responsible citizens, that is, to know their rights, to protect them and use in everyday situations. The long-term goal of education is to respect the differences that are based on universal values and development of effective protection.
