The decision to hold the conference was made by UN General Assembly Resolution A/RES/64/236 on 24 December 2009. It was intended to be a high-level conference, including heads of state and government or other representatives and resulting in a focused political document designed to shape global environmental policy.During the final three days of the Conference, from 20 to 22 June 2012, world leaders and representatives met for intense meetings which culminated in finalizing the non-binding document, "The Future We Want", which opens with: "We the Heads of State and Government and high-level representatives, having met at Rio de Janeiro, Brazil, from 20 to 22 June 2012, with the full participation of civil society, renew our commitment to sustainable development and to ensuring the promotion of an economically, socially and environmentally sustainable future for our planet and for present and future generations."

The 1710 Battle of Rio de Janeiro was a failed raid by a French privateering fleet on the Portuguese colonial city of Rio de Janeiro in August 1710, during the War of the Spanish Succession. The raid was a complete failure; its commander, Jean-François Duclerc, and more than 600 men were captured. French anger over the Portuguese failure to properly hold, release, or exchange the prisoners contributed to a second, successful raid, the following year. Duclerc was assassinated while in captivity in March 1711; his killers (and their reason for killing him) are unknown.

Four Portuguese ships of the line were lost, and the city had to pay a ransom to avoid destruction of its defences.
