This document outlines the key features and requirements for large grant proposals exploring the relationship between past, present, and future through the AHRC's "Care for the Future" theme. Proposals should be collaborative, ambitious in scale, and have the potential to make significant contributions to interdisciplinary research questions. They must engage partners outside of higher education and have strategies for knowledge exchange, public engagement, and developing early career researchers. Successful proposals will receive between £1-2 million and act as leaders and representatives within the theme.
