Which tsar rules Russia during the main historical setting of War and Peace?

Alexander I rules Russia during the main historical setting of *War and Peace*.

Tolstoy’s novel spans roughly 1805 to 1820, covering the Napoleonic Wars and their aftermath. Alexander I became emperor in 1801 after the death of his father, Paul I, and remains Russia’s monarch throughout the principal historical events depicted in the book.

The novel incorporates events such as the Battle of Austerlitz in 1805, the Treaty of Tilsit in 1807, and Napoleon’s invasion of Russia in 1812. Alexander’s relationship with Napoleon changes repeatedly: Russia fights France, reaches a temporary accommodation, and then returns to war when the alliance collapses.

Readers sometimes confuse Alexander I with Paul I, who ruled immediately before him, or Nicholas I, who succeeded him in 1825. Alexander II belonged to a later generation and became emperor decades after the events Tolstoy dramatizes. In the novel, Alexander is both a historical ruler and a figure whose public appearances affect characters such as Petya Rostov.
