In 1898, it was found that according to the 1867 Treaty, the Acre region originally belonged to Bolivia, but that region had a sizeable population of Brazilian origin. This caused many clashes, since the population did not want to submit to the Bolivian government, which tried to lease the land to the Anglo-Americans. Several riots emerged, and the situation of noncompliance lasted until 1903, when Brazil militarily occupied the territory until it finally decided the issues.
