Résumé	Multiple case-based life history research is a qualitative design that collects full biographical accounts from several purposively selected individuals and then compares those life histories across cases to identify shared patterns, divergences, and contextual influences. By treating each person's life story as one analytic case, the approach blends the depth of life history methodology with the comparative rigor of multiple case study logic, producing findings that are both individually rich and cross-case meaningful.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.
