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.
[1][2] After the uprising led by liberal general Rafael del Riego of 1820 led to the Trienio Liberal (three years of government by the Spanish liberals), that government proposed a new division of Spain in its entirety, for administrative, governmental, judicial and economic purposes, according to criteria of legal equality, unity and efficiency.
While the liberal government was crushed in 1823 by a French intervention led by the similarly restored French Bourbons, some of the reforms and ideas of the brief intermezzo would endure and form the basis of later government policy, in this case the very similar 1833 provincial subdivision of Spain which is still largely in place (albeit superseded in importance by the Autonomous Communities of Spain in many regards).
Some of these provinces were entities created for the first time, such as Almería and Málaga (carved out of the traditional Kingdom of Granada), Huelva (Kingdom of Seville), Calatayud, and Logroño; others were given new names, such as Murcia or the Basque provinces (Spanish: provincias Vascongadas).
The old provincial arrangement of Spain was restored, as was the division into kingdoms; these would remain in effect until 1833.
