Description : Mulhouse is a subprefecture of the Haut-Rhin department in the Grand Est region of Eastern France, close to the Swiss and German borders. With a population of 109,443 in 2017 in the commune and 285,121 inhabitants in 2016 in the urban area, it is the largest city in Haut-Rhin and second largest in Alsace after Strasbourg. In 58 BC a battle took place west of Mulhouse and opposed the Roman army of Julius Caesar by a coalition of Germans led by Ariovistus. The first written records of the town date from the twelfth century. It was part of the southern Alsatian county of Sundgau in the Holy Roman Empire. From 1354 to 1515, Mulhouse was part of the Décapole, an association of ten Free Imperial Cities in Alsace. The city joined the Swiss Confederation as an associate in 1515 and was therefore not annexed by France in the Peace of Westphalia in 1648 like the rest of the Sundgau. An enclave in Alsace, it was a free and independent Calvinist republic, known as Stadtrepublik Mülhausen, associated with the Swiss Confederation until, after a vote by its citizens on 4 January 1798, it became a part of France in the Treaty of Mulhouse signed on 28 January 1798, during the Directory period of the French Revolution.>
