This painting is one of the most famous works by Velázquez.
Breda is a city in the region that we know today as the Netherlands.
The Spanish army attacked Breda and surrounded the city for several months.
In the end, the city surrendered.
In the painting, the governor of the city, Justinus van Nassau, delivers the keys to the city to General Ambrogio Spinola.
Ambrogio Spinola commanded the Spanish soldiers.
The act of delivering the keys to the city was a symbol of surrender.
In the background, we can see a smoky landscape depicting the destruction caused by the war.
