The War of the Emboabas (Portuguese: Guerra dos Emboabas, lit. 'newcomers' war') was a conflict in colonial Brazil waged in 1706-1707 and 1708-1709 over newly discovered gold fields, which had set off a rush to the region between two generations of Portuguese settlers in the viceroyalty of Brazil - then the Captaincy of São Vicente. The discovery of gold set off a rush to the region, Paulistas asserted rights of discovery and non-Paulistas challenged their claims. Although the Portuguese crown sought more control in the area and the Paulistas sought protection of their claims, the Emoboabas won. The crown re-assessed its position in the region and made administrative changes subsequently.
