The Colombian–Peruvian territorial dispute was a territorial dispute between Colombia and Peru, which, until 1916, also included Ecuador.Ecuador and Colombia signed the Muñoz Vernaza-Suárez Treaty in 1916, ending their dispute. The dispute had its origins on each country's interpretation of what Real Cedulas (Royal Proclamations) Spain used to precisely define its possessions in the Americas. After independence, all of Spain's former territories signed and agreed to proclaim their limits in the basis of the principle of uti possidetis juris, which regarded the Spanish borders of 1810 as the borders of the new republics. However, conflicting claims and disagreements between the newly formed countries eventually escalated to the point of armed conflicts on several occasions.
