The Château de Malmaison is a country house (or château) in the city of Rueil-Malmaison about 12 km (7 mi) from Paris.

It was formerly the residence of Joséphine de Beauharnais, and with the Tuileries, was from 1800 to 1802 the headquarters of the French government.

Joséphine de Beauharnais bought the manor house in April 1799 for herself and her husband, General Napoléon Bonaparte, the future Napoléon I of France, at that time away fighting the Egyptian Campaign. Malmaison was a run-down estate, eight miles (13 km) west of central Paris that encompassed nearly 150 acres (0.61 km²) of woods and meadows.

Upon his return, Bonaparte expressed fury at Joséphine for purchasing such an expensive house with the money she had expected him to bring back from the Egyptian campaign. The house, for which she had paid well over 300,000 francs, needed extensive renovations, and she spent a fortune doing so. Malmaison would bring great happiness to the Bonapartes. Joséphine's daughter, Hortense would call it "a delicious spot".

Joséphine endeavored to transform the large estate into "the most beautiful and curious garden in Europe, a model of good cultivation". She actively sought out flora and fauna along with rare and exotic animals from around the world. Joséphine wrote: "I wish that Malmaison may soon become the source of riches for all [of France]"...

In 1800, Joséphine built a heated orangery large enough for 300 pineapple plants. Five years later, she ordered the building of a greenhouse, heated by a dozen coal-burning stoves. From 1803 until her death in 1814, Josephine cultivated nearly 200 new plants in France for the first time.

Napoleon Bonaparte (French: Napoléon Bonaparte [napoleɔ̃ bɔnɑpaʁt], Italian: Napoleone di Buonaparte; 15 August 1769 – 5 May 1821), was a military and political leader of France and Emperor of the French as Napoleon I, whose actions shaped European politics in the early 19th century.

Born in Corsica and trained as an artillery officer in mainland France, Bonaparte rose to prominence under the First French Republic and led successful campaigns against the First and Second Coalitions arrayed against France. In 1799, he staged a coup d'état and installed himself as First Consul; five years later the French Senate proclaimed him Emperor. In the first decade of the nineteenth century, the French Empire under Napoleon engaged in a series of conflicts—the Napoleonic Wars—involving every major European power. After a streak of victories, France secured a dominant position in continental Europe and Napoleon maintained the French sphere of influence through the formation of extensive alliances and the appointment of friends and family members to rule other European countries as French client states.

The French invasion of Russia in 1812 marked a turning point in Napoleon's fortunes. His Grande Armée was badly damaged in the campaign and never fully recovered. In 1813, the Sixth Coalition defeated his forces at Leipzig; the following year the Coalition invaded France, forced Napoleon to abdicate and exiled him to the island of Elba. Less than a year later, he escaped Elba and returned to power, but was defeated at the Battle of Waterloo in June 1815. Napoleon spent the last six years of his life under British supervision on the island of Saint Helena. An autopsy concluded he died of stomach cancer, though Sten Forshufvud and other scientists have since conjectured that he was poisoned with arsenic.
