The Kingdom of Northern Lusitania was a kingdom proposed by Napoleon in 1807 for the Monarch of Etruria, Charles II of Parma, located in the North of Portugal.
In 1807 Portugal refused Napoleon's demand to accede to the Continental System of embargo against the United Kingdom. Napoleon, having signed the Treaty of Fontainebleau on October 27, 1807, with Spain, defined the occupation of Portugal, proposing that the country would be divided into three different States:
A French invasion under Marshal Junot followed, and the capital city of Lisbon was captured on 1 December 1807. British intervention in the Peninsular War, under Arthur Wellesley, 1st Duke of Wellington, helped to restore Portuguese independence, the last French troops being expelled in 1812.
