スペイン立憲革命
The 1822 territorial division of Spain was a rearrangement of the territory of Spain into various provinces, enacted briefly during the "Trienio Liberal" of 1820–1823. It is remembered today largely as a precursor to the similar 1833 territorial division of Spain; the provinces established in the latter remain, by and large, the basis for the present-day division of Spain into provinces.
