John Quincy Adams: Diary Entries on the Adams-Onís Treaty(1819)
The career of John Quincy Adams had three distinct phases: diplomat, president, and congressman; the documents that best reveal his thinking and accomplishments are different for each time period. As a diplomat, Adams often expressed his goals in conversations with his superiors, fellow cabinet officers, and foreign diplomats meticulously recounted in his diaries. His diary entries of 1819, for example, bring to light the formulation of the Adams-Onís Treaty. Considered a triumph of American diplomacy, the Adams-Onís Treaty between the United States and Spain (and named for Adams and Louis de Onís of Spain) gave Florida to the United States and set out a boundary between the United States and present-day Mexico.
