In the twenty-first century, artificial intelligence (AI) is rapidly transforming education, communication, and social interaction. While AI technologies have the potential to promote equity, dialogue and access to information, they also raise serious ethical questions about privacy, misinformation, and algorithmic bias. This paper explores how AI can be integrated into teacher education to nurture a culture of peace and ethical responsibility among future educators. It highlights the dual role of teachers— as critical users of AI tools and as facilitators who model ethical digital behaviour for their students. The discussion draws upon examples from digital classrooms, online

conflict-resolution platforms, and community outreach programmes to illustrate how AI can support non-violence, empathy and inclusion. The paper also examines the need for policy frameworks, curricular modules and teacher training to ensure that AI applications in education do not reinforce discrimination or misinformation but instead promote cross-cultural understanding and peace-building. By focusing on teacher education, the study argues for an approach to AI that combines technological innovation with human values, thereby preparing educators and learners to act as responsible digital citizens committed to peace.
