Book excerpt: This book identifies the cultural and moral foundations of country-specific educational governance and school leadership and presents the principles of justice and the diversity of common goods that guide leadership practices in schools. It contributes to an existing research field that studies diversity and ethical leadership in schools. The social dimension of school leadership is not limited to issues related to equality and equity, or social inclusion. The capacity of leaders to promote civic-mindedness and social cooperation, consensus and acceptance of others, the right balance between freedom and duties, and reciprocity of obligations, are essential to maintain democratic rights and facilitate the life together while respecting ethnic and cultural differences. Therefore, the book gathers contributions from a range of international authors capable of reporting these moral and cultural features, while broadening the research perspectives on school leadership.
