History
The name of the region dates to the time of Marechal Cândido Rondon, who noticed a large amount of native cocao there near the bank of the Ji-Paraná River. He recommended that the guard Anízio Serrão build a house there, and Serrao asked for the site to be granted to him in 1912, calling it Cacoal. The village of Cacoal emerged in the 1960s, when the BR-364 highway began to be opened. In 1960, the rubber tapper and gold miner José Cassimiro Lopes built a shack on the left side of the highway, where he remained until the early 1970s. Work on the road intensified in the 1970s. Large sections on mud developed in the winter and drivers who were prevented from continuing their journey waited at the rubber tapper's house. They built huts where they put the goods they carried for sale to prevent them from spoiling. José Cassimiro Lopes had part of his land expropriated, leaving him with what now covers the neighborhoods Bandeirantes, Arco-Íris, Vista Alegre and part of the Industrial Sector. The fertile lands attracted migrants, who began to settle on them. Traders established themselves, offering the farmers staples and clothing. Cacoal was separated from Porto Velho and raised to the status of municipality and district with the name Cacoal by Federal Law No. 6,448, of 10 November 1977. The two districts of Cacoal and Riozinho were created on 26 November 1977.
