This paper aims to explore children’s views of social and economic sustainability and discuss how preschool can introduce peace education through encouraging children to solve conflicts peacefully, cultivating respect for diversity and developing interconnectedness of all living things. Studies have shown that there is a correlation between peace education and teaching of peace values at an early stage in reducing conflict in society (Affolter et al., 2020). Researchers argue that developing a culture of peace in early childhood education can be the best investment (Angelica Ponguta et al., 2018; Sunar et al., 2013). This study draws from Vygotsky’s socio-cultural theory that looks at the ways society impacts children’s development and behavior (Vygotsky, 1978). Employing qualitative research methodology, 403 children were interviewed from 50 preschools in 25 municipalities in Sweden. Data were analyzed thematically. The Swedish Ethical Review Authority did not raise any objection to the study. The study follows the Swedish research council guidelines, including that informed consent was negotiated with the children and parents. The findings demonstrate that preschool children are aware of the ongoing conflicts and war through news and conversations of adults. Some of them were willing to help the victims with money, toys, food and even accommodation. To contribute to the creation of a more peaceful and equitable society, preschool needs to incorporate peace education initiatives, to establish a robust foundation for fostering a sense of responsibility towards both individuals and the environment, thereby promoting the welfare of both current and future generations (United Nations 2015).
