Why was the capital moved from salvador to rio de janeiro?

The capital of Brazil was moved from Salvador to Rio de Janeiro in 1763 primarily for strategic reasons. Salvador, located in the northeast, was less accessible for governance and trade as the country expanded. Rio de Janeiro's more central location facilitated better communication and transportation, making it a more effective hub for the growing population and economy. Additionally, the move reflected the shift of economic power towards the southeast, where coffee and other industries were emerging.
