Louis Julius was born in
Toulouse on 2 May 1660 to Count
Eugene Maurice of Soissons and the noblewoman
Olympia Mancini. From a young age he was trained for a military career. In 1672, Louis Julius' uncle,
Emmanuel Philibert, Prince of Carignano invited him to
Piedmont to serve the
Duchy of Savoy. In 1678, Duke
Victor Amadeus II of Savoy appointed him Lieutenant General of the province of
Saluzzo. In 1682, he was entrusted with the command of a regiment of
Dragoons, and the following year, following the advance of the massive
Ottoman Armies, he joined the service of the army of the
Holy Roman Empire. Louis Julius was injured due to a fall from his horse in one of the first clashes provoked by the
Turks to conquer
Vienna, two months before the famous
Battle of Vienna. ==References==
