In A.D. 774 Charlemagne conquered the Lombard
Kingdom, after he had defeated and
banished the last Lombard king,
Desiderio. Charlemagne acquired the title of “king of Lombard and Frank
people” and, in A.D. 800, he also became emperor.
After his last descendants died, the imperial crown passed into the hand
of a family whose members were called Guidonidi. Among them, there were
the Counts of Lecco, who dominated the lands of the valley of the Adda
river till the A.D. 975 when Attone, the last Count, died. In that year
the valley was divided in two parts,
physically separated by the Adda river and assigned to different
the lands on the eastern side, nowadays called the St. Martin Valley,
became properties of the Curia of Bergamo; the lands on the western one,
called Brianza like the mountain overlooking that region, became
properties of the Martesana District. After those events, the Comacina
lost its identity definitively.
On the left, the main relationships between the
Lombard royal families and the Frank ones. The Counts of
Lecco are highlighted in yellow (to enlarge, click on the image).
