Napoleonic Wars
In 1808, the Peninsular War began when Napoleon crowned his brother Joseph Bonaparte as King of Spain, and France fought British, Spanish, and Portuguese troops. In 1809, the Finnish War began between Russia and Sweden after Sweden and Portugal made peace with France. That led to the annexation of Finland by Russia and the decisive failure of Sweden. In 1811, France and Russia made disagreements again, and Napoleon allied with Prussia and Austria and invaded Russia.
