Bradenton FL, site of DeSoto's first landing in America and an annual re-enactment. I ask Ranger Dan, who plays the fray, to read the Spanish text of the 1513 Requirement, which was read to natives (or empty beaches) upon landing during the Conquest era. A notary witnessed and signed each reading.
I'd like to think that the Requirement was the first legal disclaimer in the Americas. The document absolved the conquistadors of responsibility for any subsequent damages or death, giving listeners a clear choice between conversion and submission, or war and ruin.
