This book delves into the experiences of Ukrainian women forced to leave their country in search of refuge following the devastating escalation of conflict with Russia in February 2022, exploring the diverse forms of capital they bring with them and develop on the way. Drawing on extensive original research, the book focuses on Ukrainian female war migrants in Poland-a country that, even before the war, served as the primary destination for Ukrainian labour migrants and now hosts a significant number of refugees. The book examines the human, social, psychological and economic capital Ukrainian women bring with them, alongside their participation in the local labour market, their mobilization of resources, and the acquisition of new skills and knowledge. Far from merely documenting this historic wave of migration, the book highlights the potential of Ukrainian women to become key agents in Ukraine's post-war reconstruction and development, by bringing social remittances such as ideas, practices, and norms, back home with them. Integrating advanced statistical analysis of data from over 340 migrants with rich qualitative insights, this book will be an important resource for researchers studying migration, security, politics, sociology, and development. It also provides valuable insights and data for NGOs and policymakers working to support Ukrainian migrants in Poland and beyond.
