 chile is divided into 15 regions (in spanish, regiones; singular regiÃ³n), which are the country's first-level administrative division. each region is headed by an intendant (intendente), appointed by the president, and an indirectly-elected body known as regional board (consejo regional). regions are divided into provinces (second-level administrative division), each headed by a governor (gobernador), appointed by the president. there are 54 provinces, in total. provinces are further divided into communes (third and lowest level administrative division), which are governed by municipalities. ==naming== each region is given a roman numeral, followed by a name (e.g. iv regiÃ³n de coquimbo, read as "fourth region of coquimbo" in spanish). when the regional structure was created, roman numerals were assigned in ascending order from north to south, with the northernmost region designated as i (first) and the southernmost region as xii (twelfth). the santiago metropolitan region, located in the center of the country and home to the country's capital santiago, was excluded from this naming scheme and given instead the initials rm, standing for regiÃ³n metropolitana ("metropolitan region" in spanish). with the creation of regions xiv in the south and xv in the north (xiii is not used) in 2007, the north-south roman numeral order was broken. ==history of the regional structure== the current administrative divisions of chile were created in 1974 and limited to 13 regions (this limitation was eliminated in 2005 via a constitutional reform). previously, chile was divided into 25 provinces, which were further divided into departments, and then into communes. the new territorial organization was implemented in phases with some initial "pilot regions" beginning to operate in 1974, extending the process on january 1, 1976 to the rest of the country. the santiago metropolitan region began to operate in april 1980. in december 2006, two new regions were created: the northern arica and parinacota region, by taking out the two northernmost provinces from the tarapacÃ¡ region; and los rÃ­os region in the south, encompassing the provinces of valdivia, formerly part of the los lagos region, and ranco, formerly part of valdivia.la naciÃ³n both regions became operative in october 2007. ==list of regions==  150px|right {| class="wikitable sortable" |- bgcolor=#ececec ! scope="col" class="sortable" | key ! name (english/spanish) ! capital ! ar
