The video goes through what I do consider as Spanish history from the Visigothic era until nowadays.
In order to keep the video understandable, I decided to divide it into two parts : one showing the continental possessions only, and the second one showing overseas territories.
Regarding the part about colonies : claimed, occupied or tributary/vassal countries or tribes are not evoked.

2 : Viscounty of Béziers
3 : Viscounty of Lodeva

5 : County of Conflent
