The science of social work plays an important role in advocating for and protecting individuals, families, and communities, regardless of personal and biological characteristics. This scientific and professional responsibility carries the weight of many challenges, as it necessitates continuous alignment with the environment, socio-political and economic conditions, as well as the changing needs of the particular population.

In order to adopt a complementary and respectful practice towards individuals whose gender, gender expression, and sexuality do not conform to heterosexual and predefined norms, this book focuses on presenting the historical and social conditions that have influenced the experiences of LGBTQI+ individuals, while scientifically addressing the established knowledge regarding the intersectionality of individuals and the need to avoid generalizing knowledge.

The evolution of social work concerning LGBTQI+ identities is vital for the creation of a fair and inclusive society. As the needs of LGBTQI+ individuals become more visible, social work must adapt, focus on specialized training, and provide meaningful and effective support without prejudices and stereotypes. Such changes pertain not only to addressing inequalities but also to creating a safe environment where every individual can express themselves freely and access services without discrimination and marginalization.
