Editing Cantabria (section)

===''Comarcas'' (regions)===
The Cantabrian legislation divides the autonomous community in administrative regions called ''comarcas'', but traditionally, other subdivisions of the territory have been used.

*'''Administrative regions'''
''Law 8/1999 of ''Comarcas'' of the Autonomous Community of Cantabria'' of 28 April 1999 establishes that the comarca is a necessary entity, integral in the territorial organization of the region. This law opens the development of the ''comarcalization'' in Cantabria promoting the creation of ''comarcal'' entities, which have barely begun to appear. The law establishes that the creation of comarcas will not become mandatory for the whole territory until at least the 70% of it had not been ''comarcalized'' by its own will. {{Clarify|reason=confusing|date=August 2015}} It also adds that Santander will not ruled by comarcalization and should establish its own [[metropolitan area]] instead.{{citation needed|date=August 2015}}

''Comarcas'' in Cantabria have not reached administrative nature and barely have definite borders. Only Liébana for its geographic position in Picos de Europa, Trasmiera and Campoo, in the Ebro basin are established are clearly defined ''comarcas'' in the region. Nevertheless, functional differences in the territory can be distinguished, dividing it in the following areas: [[Santander Bay]], of industrial and urban nature; [[Besaya valley|Besaya]], also industrial; [[Saja and Nansa valleys|Saja-Nansa]], eminently rural; [[Western coast of Cantabria|Western Coast]], which has urban character; [[Eastern coast of Cantabria|Eastern Coast]], vacational; the traditionally renowned [[Trasmiera]]; rural [[Valles Pasiegos|Pas-Miera]]; [[Asón valley|Asón-Agüera]], also mainly rural; the very well defined [[Liébana]], and [[Campoo|Campoo-Los Valles]], rural and industrial by regions.

*'''Natural regions''' (regarding geographical features)
**Coastal strip
**Central strip (Cantabrian valleys perpendicular to the coast): Liébana, Saja and Nansa, Besaya, Pas and Miera (or Valles Pasiegos), and Asón-Gándara valleys.
**Southern strip (Rivers Ebro and Duero's basins): Campoo and Southern valleys
*'''Historic regions'''
Until the 13th century, Cantabria was organized in valleys, as was typical in all of northern Spain. From then on, it was substituted by the organization in cities, towns or historic ''comarcas'' that grouped several valleys.
