Flag of the Transition (1817–1818) thumb| Flag of the Transition (1817–1818). The victory at the Battle of Chacabuco on 26 May 1817 gave way to a new period known as the Patria Nueva (New Fatherland). A new flag was adopted that day, known today as the Flag of the Transition (Bandera de la Transición), and it is recognized as the first national flag and the last flag used until the one used currently. It was widely publicized at the time that the design was attributed to Juan Gregorio de Las Heras. This flag had three equal stripes: blue, white, and red, which is identical to the flag of pre-communist Yugoslavia (the flag of Serbia and Montenegro later). The bottom red strip replaced the yellow from the flag of 1812. The origin of the flag's colors would be based on the description given by Alonso de Ercilla as those of the insignia of the Mapuche troops. The significances of these colors were equivalent to those of the Patria Vieja, except that the yellow replaced the red to represent the blood that had been shed during the many conflicts.
