Splendid isolation is a term used to describe the 19th-century British diplomatic practice of avoiding permanent alliances from 1815 to 1902. The concept developed as early as 1822, when Britain left the post-1815 Concert of Europe, and continued until the 1902 Anglo-Japanese Alliance and the 1904 Entente Cordiale with France. As Europe was divided into two power blocs, Britain became aligned with the French Third Republic and the Russian Empire against the German Empire, Austria-Hungary and the Kingdom of Italy.
