The Carolingian Empire (test for using goconqr)

The Muslims were defeated in 732, at the Battle of Poitiers by:

Who deposed the last Merovingian king and became the first king of the Carolingian dynasty?

Who was crowned Emperor by Pope Leo III at Rome in 800?

Who was the only son to survive Charlemagne and inherit the Carolingian Empire?

Charlemagne established his residence in [blank_start]Aachen,[blank_end] from where he ruled his empire, which he organised into counties and [blank_start]marks[blank_end]. [blank_start]Counties[blank_end] were the territory of a city and were administered by [blank_start]counts.[blank_end] Marks were border areas, with an army under the command of a [blank_start]marquis.[blank_end]

Charlemagne directly appointed the counts and marquises who had to swear [blank_start]loyalty[blank_end] to him. He also had the [blank_start]missi dominici,[blank_end] a kind of inspector who kept an eye on the most powerful counts, marquises and bishops.

After the death of Louis the Pious, the Empire was divided among his sons: [blank_start]Charles the Bald[blank_end] received the western part, [blank_start]Louis the Germanic[blank_end] the eastern part, and [blank_start]Lotarius[blank_end] inherited the title of emperor and the territory in between. The brothers fought against each other until they finally signed the [blank_start]Treaty of Verdun[blank_end] in 843. When Lotarius died, his brothers divided the territory, thus creating the kingdom of France and the [blank_start]Holy Roman Empire.[blank_end]
