New Historicism is a form of literary theory whose goal is to understand intellectual history through literature, and literature through its cultural context, which follows the 1950s field of history of ideas and refers to itself as a form of "Cultural Poetics." It was first developed in the 1980s, primarily through the work of the critic and Harvard English Professor Stephen Greenblatt, and gained widespread influence in the 1990s.
H. Aram Veeser, introducing an anthology of essays, The New Historicism (1989), noted some key assumptions that continually reappear in New Historicism; they are:
"Sub-literary" texts and uninspired non-literary texts all came to be read as documents of historical discourse, side-by-side with the "great works of literature". A typical focus of New Historicist critics, led by Stephen Orgel, has been on understanding Shakespeare less as an autonomous great author in the modern sense than as a means of reconstructing the cultural milieu Renaissance theatre—a collaborative and largely anonymous free-for-all—and the complex social politics of the time. In this sense, Shakespeare's plays are seen as inseparable from the context in which he wrote (see contextualism, thick description). Influential historians behind the eruption of the New Historicism are Lynn Hunt and Michel Foucault, as they both taught at UC-Berkeley during its rise as a postmodern approach to history.
In this shift of focus, a comparison can be made with the best discussions of works of decorative arts. Unlike fine arts, which had been discussed in purely formal terms, comparable to the literary New Criticism, under the influences of Bernard Berenson and Ernst Gombrich, nuanced discussion of the arts of design since the 1970s have been set within social and intellectual contexts, taking account of fluctuations in luxury trades, the availability of design prototypes to local craftsmen, the cultural horizons of the patron, and economic considerations—"the limits of the possible" in economic historian Fernand Braudel's famous phrase. An outstanding pioneer example of such a contextualized study was Peter Thornton's monograph Seventeenth-Century Interior Decoration in England, France and Holland (1978).
