Review Questions
How did natural changes in the Rio Grande contribute to the Chamizal Dispute between the United States and Mexico?
Natural changes in the Rio Grande played a critical role in the Chamizal Dispute as shifting riverbanks altered the previously established boundary line set by the Treaty of Guadalupe Hidalgo. Flooding and erosion led to significant land being lost or gained by both countries over time, creating confusion about ownership and prompting both nations to stake claims on the disputed territory. This ongoing geographical evolution made it challenging to define a clear border, ultimately leading to decades of conflict.
Evaluate the significance of the joint boundary commission formed in 1911 regarding the Chamizal Dispute and its effectiveness in resolving tensions.
The formation of the joint boundary commission in 1911 was significant because it represented an attempt by both countries to collaboratively address the Chamizal Dispute rather than resorting to unilateral actions or military conflict. However, while the commission conducted investigations and proposed solutions, their findings were not fully accepted or implemented until 1963. This long gap reflects not only bureaucratic challenges but also underlying national sentiments that complicated bilateral negotiations over territorial integrity.
