Post-Congress of Vienna: Great Britain and Austria Emerge as Leading Powers

The 1815 Congress of Vienna reshaped Europe. The two countries gaining the most influence were:

• Great Britain: Emerged as the world's preeminent naval and economic power with a vast empire.
• Austria: Restored as a dominant Central European power.

Together they anchored the new Concert of Europe, a system of great-power consultation to maintain peace and balance. Their leadership defined European diplomacy for decades.
