The Political Constitution of the Republic of Chile of 1980 is the fundamental law in force in Chile. It was approved and promulgated under the military dictatorship headed by Augusto Pinochet, being ratified by the Chilean citizenry through a referendum on September 11, 1980, although being held under restrictions and without electoral registers. The constitutional text took effect, in a transitory regime, on March 11, 1981, and then entered into full force on March 11, 1990, with the return to electoral democracy. It was amended for the first time in 1989, and afterward in 1991, 1994, 1997, each year from 1999 to 2001, 2003, each year from 2007 to 2015, and each year from 2017 to 2021, with the last three amendments concerning the current constituent process. In September 2005, under Ricardo Lagos's presidency, a large amendment of the Constitution was approved by parliamentarians, removing from the text some of the less democratic dispositions coming from Pinochet's regime, such as senators-for-life and appointed senators, as well as the armed forces' warranty of the democratic regime.
A voting age is a minimum age established by law that a person must attain before they become eligible to vote in a public election. The most common voting age is 18 years; however, voting ages as low as 16 and as high as 25 currently exist (see list below). Most countries have set a minimum voting age, often set in their constitution. In a number of countries voting is compulsory for those eligible to vote, while in most it is optional.

Women's suffrage in Francoist Spain and the democratic transition was constrained by age limits, definitions around heads of household and a lack of elections. Women got the right to vote in Spain in 1933 as a result of legal changes made during the Second Spanish Republic. Women lost most of their rights after Franco came to power in 1939 at the end of the Spanish Civil War, with the major exception that women did not universally lose their right to vote. Repression of the women's vote occurred nevertheless as the dictatorship held no national democratic elections between 1939 and 1977.
