In reality, there is not much difference between Perigord and Dordogne. Historically, however, Perigord refers to a territory that was part of the Duchy of Aquitaine that was just about identical as Dordogne today with an additional territory to the south in what was the Quercy region of France. Dordogne refers to the name of the Departement that was created during the French Revolution and takes its name from the main River that crosses the area.The name Perigord could have disappeared with time but the values and identity of the name are so strong, bonding it with local History, Food & gastranomy, that it has become a 'brand' of its own. That is why, when traveling to the Dordogne, you will certainly encounter the names of the 4 tourist regions which are Perigord Vert (green for the prairies of Dordogne to the North), Perigord Blanc (White for the limestone area), Perigord Noir (Black for the color of the local oak trees) and Perigord Pourpre (purple for the vineyards towards Bergerac).For many travelers this is confusing but whatever the name of the area Perigord or Dordogne, you are in one of the most beautiful regions of France.
