The "Guerra Grande" refers to a significant conflict in Uruguay that took place from 1839 to 1851. It was primarily a civil war between two political factions: the Blancos (or National Party) and the Colorados (or Colorado Party). The war was marked by battles over political power, land, and social issues, leading to widespread devastation and loss of life. The conflict also had regional implications, drawing in neighboring countries like Argentina and Brazil. The Blancos and Colorados had different visions for Uruguay's future, which fueled the intensity of the war. Ultimately, the Guerra Grande shaped Uruguay's political landscape and contributed to the establishment of a more stable government.
