Mello negotiated with a large landowner of the region to begin selling the lots.

The lands were on the banks of the Rio Verdão and near the Brasília – Acre highway, which was under construction at the time.

Origin of the name The name of the town, Acreúna, comes from a combination of Acre, final destination of the highway which crosses the town, and Una, a tribute to Paraúna, the municipality where it had been located before becoming a separate municipality.

It became a district in 1968 and, thanks to its rapid population growth and economic development, it separated from Paraúna in 1976 to become an independent municipality.

The economy is based on agriculture, with a great production of sugarcane, cotton, corn, and soybeans (see below).
