The Marca Hispanica, also known as Spanish March or March of Barcelona, is a buffer zone beyond the province of Septimania, created by Charlemagne in 795 as a defensive barrier between the Umayyad Moors of Al-Andalus and the Frankish Kingdom.In its broader meaning, Marca Hispanica refers to a group of early Iberian lordships or counts created by the Franks, of which Andorra is the sole autonomous survivor.

As time passes, these lordships merge or gain ndependence from Frankish imperial rule.
