This map, published as part of the National Atlas of Spain in 2021, shows the territorial organisation of Spain during the 18th century.

The different colours of the map show mainly the provincial intendancies into which Spain was divided in the 18th century, although with some exceptions. Vizcaya, Guipúzcoa, Álava and Navarre, since they still maintained their foral system, were not considered provincial intendancies per se. Other provinces such as the Canary Islands and Asturias, despite being considered provinces, did not have an associated intendancy. Extremadura, on the other hand, despite being considered a single province at the time, had two intendancies, one in Badajoz and the other in Cáceres.

At the end of the 18th century there began to be multiple administrative changes that began to create new provinces, mainly dividing Granada and Seville, although later the division and reorganisation of other provinces would follow. Finally, Javier de Burgos' reform of 1833 established the current provinces into which Spain is divided.

This map of Spain by Tomás López shows this same division, but on a map drawn at the time. In this link you can also find detailed provincial maps of the period.
