The Revolución de Mayo began on or around 18th May 1810 and ended a week later on 25th May 1810 when the ruling Spaniards were kicked out and locals took over control of the region that’s now, mainly, known as the Republic of Argentina.
So the country celebrates 200 years of existence today. ¡Feliz Cumple, Ches!
