Focusing on the 20th century, this talk examines the process by which new peers’ titles were chosen and approved, the considerations which peers took into account and the principles which governed title selection. Garter King of Arms, who was charged with settling peers' titles on behalf of the Crown, had guidelines to help ensure that titles were dignified and distinctive, and peer-designates could be disappointed if he felt unable to approve their first choice. Consultation with other parties might also be required, yet even titles which secured approval sometimes generated criticism after being announced. This presentation will also consider how the guidelines developed and how peers’ title preferences evolved during this period.
