Mapasingue was an
hacienda in the 19th century. In November 1859, during the first
Ecuadorian–Peruvian War, a
Peruvian army contingent occupied its lands as a result of an agreement between Peruvian President
Ramon Castilla and Supreme Chief of Guayas Guillermo Franco. The peace treaty signed between the two regimes in 1860 was known as the
Treaty of Mapasingue. == References ==
