Middle Francia (Latin: Francia media) was a short-lived Frankish kingdom which was created in 843 by the Treaty of Verdun after an intermittent civil war between the grandsons of Charlemagne resulted in division of the united empire. Middle Francia was allocated to emperor Lothair I, the eldest son and successor of emperor Louis the Pious. His realm contained the imperial cities of Aachen, the residence of Charlemagne, as well as Pavia but lacked any geographic or ethnic cohesion which prevented it from surviving and forming a nucleus of a larger state, as was the case with West Francia and East Francia.
Middle Francia was situated between the realms of East and West Francia, and comprised the Frankish territory between the rivers Rhine and Scheldt, the Frisian coast of the North Sea, the former Kingdom of Burgundy (except for a western portion, later known as Bourgogne) and Provence, as well as parts of northern Italy. Following the 855 partition, Middle Francia became only a geographic term.
