Orléanais
The Duchy of Orléanais () is a former province of France, which was created during the Renaissance by merging four former counties and towns. However after the French Revolution, the province was dissolved in 1791 and succeeded by five ''départments'' (less some communes to others). Provided by Wikipedia-
