Ecuador and Peru share a long
border made up largely of jungle and high mountains. As
is the case with many such borders around the world,
disputes arise, and conflict breaks out. In this century,
these Latin American neighbors have fought three times,
(1941, 1981 and 1995), over the area known as the
Cordillera del Condor region. After much bloodshed and,
since 1995, much negotiating, these Andean nations signed
a peace accord on October 26,

Ecuador-Peru Border Wars in 1981 and 1995 Pin
territorial dispute between Ecuador and Peru originated
in Spanish Colonial times. Upon independence, Ecuador
joined what is now known as"Great Colombia", comprised of
the territories of Venezuela, Ecuador, Colombia and
Panama (then a part of Colombia). In 1829, the Treaty of
Peace and Limits of Guayaquil was signed. Subsequently,
in 1830, Pedemonte-Mosquera Protocol was signed. They
established the Marañon-Amazon River as the border
between Peru and Ecuador; however, Peru has contested
these agreements. Between 1936 and 1938, representatives
from Ecuador and Peru attempted to negotiate a treaty in
Washington, D.C., consequently, the Peruvians withdrew
from the negotiations. A series of border clashes were
fought in the years between 1938 and 1940. Peru decided
to settle the matter by force after a border clash in
was unprepared to meet the July 5 Peruvian invasion. The
much larger Peruvian army of 13,000 men, supported by a
battalion of armor, together with artillery and air
support (known as Group of the North or agrupamiento del
Norte commanded by General Eloy G. Ureta), moved quickly
into the southern coastal province of El Oro, threatening
Guayaquil. The fewer than 1,800 Ecuadorian troops in the
area lacked air cover and could offer only limited
resistance. The Ecuadorian president's fear of being left
unprotected from his political opponents led him to keep
the nation's best fighting forces in Quito. Peruvian
forces also moved into the disputed Amazonian territory
without significant opposition. Peruvian troops
continuously attacked the nation's southern and eastern
provinces until a ceasefire went into effect on July 31.

with Ecuador was a major success for Peruvian forces. By
