Passage: English: "Great East"; German: Großer Osten—both in the Alsatian and the Lorraine Franconian dialect), previously Alsace-Champagne-Ardenne-Lorraine (ACAL or less commonly, ALCA), is an administrative region in northeastern France. It superseded three former administrative regions—Alsace, Champagne-Ardenne, and Lorraine—on 1 January 2016, as a result of territorial reform which was passed by the French legislature in 2014. Alsace-Champagne-Ardenne-Lorraine was a provisional name, created by hyphenating the merged regions in alphabetical order; its regional council had to approve a new name for the region by 1 July 2016. France's Conseil d'État approved Grand Est as the new name of the region on 28 September 2016, effective 30 September 2016. The administrative capital and largest city is Strasbourg.
