When Napoleon I ordered the invasion of Portugal in 1807 because it refused to join the Continental System, the Portuguese Braganzas moved their capital to Rio de Janeiro to avoid the fate of the Spanish Bourbons (Napoleon I arrested them and made his brother Joseph king). When the French general Jean-Andoche Junot arrived in Lisbon, the Portuguese fleet had already left with all the local elite.
