Salvador Allende, who was a doctor by profession, was elected as president of Chile in 1970, on his fourth attempt at the election.
It should be noted that he was the first socialist president who came to the presidency of a Latin American country through suffrage and the first to govern with communist support, due to his <u>evident leftist tendencies</u>.
His term was interrupted by a coup d'état that unleashed his controversial death on September 11th, 1973. Movement led by General Augusto Pinochet and supported by the United States .
The tribes that were affected by this treaty were the Walla Walla and the Cayuse. I would say that the answer is the Walla Walla tribe. Hope it helps :)
