Antoine-François Brenier de Montmorand served as a French general of division during the period of the First French Empire and became an officer of the Legion of Honour.

The invasion of Portugal saw an Imperial French corps under Jean-Andoche Junot and Spanish military troops invade the Kingdom of Portugal, which was headed by its Prince Regent João of Bragança. The military operation resulted in the occupation of Portugal. The French and Spanish presence was challenged by the Portuguese people and by the United Kingdom in 1808. The invasion marked the start of the Peninsular War, part of the Napoleonic Wars.
