In 1789, some political events of the French Revolution took place in France. They were based on the three principles: "Liberty, Equality and Fraternity." The main countries of Europe allied up against France, because they did not want these ideas “come” to them. Prince D. João has agreements with Spain and England separately. At this time the Spanish government asked for help. It wanted Portugal to participate in the Campaign of Roussillon (Eastern Pyrenees). While the Portuguese fought in the Pyrenees, Spanish delegates negotiate the peace with France, in secret. Portugal was in a difficult situation in France and Spain tried to break our alliance with England and our country seeks to maintain neutrality. The French have dominated almost all of Europe, except England. Then, the French blocked the ports of Europe to the British ships. Portugal tries to save time, but Napoleon gives us a deadline (September 30, 1807) to join the blockade, declaring war against England and confiscate the property of British citizens residing in our country. Portugal has not replied. On 27th October 1807, France and Spain reaffirmed their alliance, through the Treaty of Fontainebleau, which provided, in a secret agreement, the division of Portugal. But the invasion of our country had already been taken by Napoleon. Acros s Spain, the French army, commanded by Junot, reached Alcântara, in November 17th, 1807. With the help of three divisions Spanish are about to enter Portugal by the Beira Baixa.
