Though a French historical school, the Annales, whose journal was first published in 1929, have been extremely influential on the practice of history in Britain and indeed worldwide. Its founders, Marc Bloch and Lucien Febvre, sought to break down the barriers between history and other disciplines, incorporating ideas from literature and psychology as well as the social sciences in an attempt the mentalités of particular historical periods. In the 1940s Fernand Braudel developed the 'total history' paradigm with his seminal work on the Mediterranean, which introduced the idea of different levels of historical time, or durées. Past and Present and the historians connected with it were to a certain extent inspired by the Annales, though its influence has waned in the era of post-modernism.
