tratado de adams-onís (10. 565)

Also known as the Florida Purchase, the agreement that ceded the peninsular territory to the United States and defined the border between the USA and New Spain, a continual point of contention, was signed on this day in 1819 and going into effect two years later, it came at a time when Florida was becoming a liability and indefensible for the colonial power (see also) and amidst of wars of independence in Latin America. Negotiated by John Quincy Adams, then Secretary of State under President James Monroe and the diplomatic envoy of King Ferdinand VII, Luis de Onís y González-Vara, it was considered a decisive if not exploitative victory for the US, having already annexed the western part of the territory and the counter-intuitive support for the break-away province of the State of Muskogee, briefly tolerated as a refuge for escaped enslaved people, Native American organisers and outlaws massing in Spanish Florida as a destabilising factor until their purpose was served.
