Across much of human civilisation, marriage was regarded not merely as a private contract but as the cornerstone of social order. The ideals of lifelong fidelity, stable parenthood and mutual responsibility were upheld by virtually every major civilisation and religion. During the past six decades, however, unprecedented social, technological and economic transformations have altered both attitudes and behaviour concerning sexuality, marriage and family life.
The commercialisation of sex, the digital revolution, changing gender roles, declining religious participation, delayed marriage and growing individualism have collectively reshaped intimate relationships across many societies. While these changes have expanded personal freedoms and challenged long-standing inequalities, they have also generated important questions concerning family stability, demographic sustainability, mental well-being and social cohesion.
