discourse of development, which emerged after World War II with goals such as improving quality of life, making people happy, and expanding freedom. This discourse encompasses concepts like production, reproduction, wealth, poverty, government, people, politics, equality, inequality, culture, population, life, and death. As a material knowledge, development has gained a special position at the center of social actions and government planning, aiming to intervene in the economic, social, and political life of people.However, this knowledge has become controversial in the modern era, partly due to the failure of its 20th-century goals and slogans, and partly due to the dominance of political governance in the dimensions of development. This raises the question of whether life is the foundation of politics or the subject of politics. If the former, the goal is a kind of development action through population regulation, health policies, and environmental protection. If the latter, the goal is to guide and control life processes through development.Biopolitics is a window into the modern world, an era marked by the expansion of biomedical and technoscientific technologies, increased life expectancy, concerns about preserving life and the environment, and the illusions arising from these processes for the future.The journal "Biopolitics and Development" emerges from a historical context where the failure of holistic approaches to development, the supremacy of neoliberalism, the prominence of culture over economics, and the transformation of the body and life into subjects of politics are discussed. In this context, the question arises: how can we understand the discourse and practice of development and its historical and contemporary functions? And how can we comprehend the links between development, politics, and life in the hegemony of neoliberalism?
