In Bolivia, Mother's Day is celebrated on 27 May. El "Día de la Madre Boliviana" was passed into law on 8 November 1927, during the presidency of Hernando Siles Reyes. The date commemorates the Battle of La Coronilla, which took place on 27 May 1812, during the Bolivian War of Independence, in what is now the city of Cochabamba. In this battle, women fighting for the country's independence were slaughtered by the Spanish army. It is not a public holiday, but all schools hold activities and festivities throughout the day.
