Origin of identity
historical usage of identity
“One’s personal characteristics, or the sense of who one is, as perceived by the person or by others,” is a meaning of identity that dates from the early 18th century. Since then, issues of personal identity, especially sexual and gender identity, have provoked discussions about one’s overlapping roles in society. The phrase identity politics “political activity based on or catering to the cultural, ethnic, gender, racial, religious, or social interests that characterize a group identity” was coined in 1973.
