Religious Diversity and Migration: Exploring Research Trends in an Increasingly Secular Spain

Secularism and the public management of religious diversity have gone hand in hand in public and academic debates in recent decades. Meanwhile, many of the elements related to secularism and the presence of religions in western societies have been conditioned by the migratory phenomenon. At the same time, Spain has been exposed to a relevant qualitative change in its socio-religious composition, evolving from a mainly Catholic society to a less religious and more diverse one, equating to other European societies. Many controversial issues have arisen in recent decades, such as the role of religion in the public life, the relations between religion and the state and the emergence of a more plural society, having a special role the migratory phenomenon. This contribution approaches these issues through analysis of the linkage between migration and religious diversity studies within a secular framework. The paper aims to analyze this reality, focusing on the main research trends in PhD studies in the past 20 years. The article reveals a growing interest in doctoral research from a multidisciplinary perspective in the field of religion and international migration, the contexts in which this research has been carried out, as well as its main themes and methods of approach. The intent is to study the religious phenomenon linked to immigration, because this reflects, at least to a certain extent, the concern for understanding the presence of religion in an increasingly secular society, such as in Spain.
