In 1719 a Paulista, Pascoal Moreira Cabral, was hunting Indians along the Rio Cuiabá when he found gold. A gold rush followed, but many of those seeking gold never reached the new settlement at Cuiabá. Traveling more than 3000km from São Paulo by river took five months; along the way, gold seekers found little food, many mosquitoes, dangerous rapids, lengthy portages, disease and incredible heat.
With the end of the gold boom and the decay of the mines, Cuiabá would have disappeared, except that the soil along the Rio Cuiabá allowed subsistence agriculture, while the river itself provided fish.
By 1835 the town was the capital of Mato Grosso but, apart from a brief resurgence as a staging point for the war against Paraguay in the 1860s, it remained a backwater. Today, thanks mostly to the construction of Brasília and a massive agri-economy, Cuiabá has finally been propelled into the modern world.
