The Treaty of Badajoz (also known as the Peace of Badajoz) was signed in Badajoz on 6 June 1801 between John VI of Portugal and representatives from the Kingdom of Spain. Based on the terms of the accord, the Kingdom of Portugal agreed to cede Olivença (along with paying an indemnity to Spain). Moreover, Portugal was required to close all ports to the British. On a sidenote, John VI was forced to sign the accord as a result of the Spanish army (along with a French auxiliary corps) having been dispatched across the Portuguese frontier. The treaty was reinforced and slightly altered during a special convention (i.e. Treaty of Madrid) that was held on 29 September 1801 whereby Portugal was forced to pay France a total of 20 million francs.
