When it was formed during theFrench Revolution, as of March 4, 1790 in fulfillment of the law of December 22, 1789, the new department combined parts of theprovinces of southernBurgundy andBresse, uniting lands that had no previous common history nor political unity and which have no true geographical unity. Thus its history is that of Burgundy, and is especially to be found in the local histories ofAutun,Mâcon,Chalon-sur-Saône,Charolles andLouhans.
