MID#2321
Dispute Number: 2321
Date(s): June 1906 to December 1906
Participants: 145 Bolivia/135 Peru
Outcome (and Settlement): Unclear (Negotiated)
Fatalities: None
Narrative: Bolivia occupied the disputed Madre de Dios territory, claimed by Peru,
which occurred while the long-disputed territory was under arbitration in Argen-
tina. Peru protested the occupation precisely because the area was under arbitration.
Bolivia in turn complained to the arbiter—Julio A. Roca, Argentine president—in
May 1906 that Peru was doing the same. Bolivia agreed to withdraw from what it just
occupied if Peru agreed to do the same for a stretch of territory that it also occupied.
The incident was closed in August 1907.

Dispute Number: 1180
Date(s): December 7, 1910 to March 30, 1911
Participants: 145 Bolivia/135 Peru
Outcome (and Settlement): Compromise (Negotiated)
Fatalities: 1–25 deaths
Narrative: The end of 1910 saw a string of incidents between militias of Bolivia and Peru
on the Manuripi River. Concerned over the incidents, the Peruvian and Bolivian foreign
ministers concluded an agreement on March 30, 1911, expressing remorse for the clashes,
which each assured was not an official state action, and calling for a commission to inves-
tigate the incidents. Each government’s commission was to receive claims and proofs for
purposes of indemnity. After six months, both commissions were to report their findings
for a friendly settlement and resort to The Hague for unappealable arbitration if there was
no agreement between the two. A corollary protocol was signed on April 15, 1911. This
called for a mixed commission to deal with the frontier. If there was any disagreement or
uncertainty with the commission’s findings, the Royal Geographical Society of London
would serve as arbiter and its decision would be binding and unappealable.
Coding changes: Start Date changed from November 19, 1910.
