Social identity - how people define and categorize themselves - is constructed and expressed through cultural practices, cultural production and corporeality. This text takes a theoretical approach in viewing social identity as an intricate "warp and weft" in which "we-identities" are more than mere agglomerations of single threads or collectives of individual "self-identities", such as ethnicity or gender. This is important for medieval Britain prior to the 11th century due to the ways in which aspects of identity have been used as defining criteria in both modern scholarship and in contemporary historical texts.
