How do concepts such as ‘the body’, ‘intimacy’, ‘adventure’ and ‘intersectionality‘ shape our engagement with gender history? In this 40th anniversary edition of the Yearbook we revisit the question how concepts ‘live’ in gender research practices and what it means to ‘do’ gender history in 2021. Contributors include experienced researchers who have spent years, sometimes decades, contemplating the conceptual background of their work as well as scholars who have come to the field more recently and who therefore provide a different insight. As such this Yearbook shows how certain concepts travel within academic culture across the Low Countries, revealing not so much the theoretical underpinnings of the field, but rather how these theoretical underpinnings find a home in individual research practices and may be used in surprising ways.
