She was launched in 1859 following the Crimean War, in response to new developments in naval gun technology, especially the Paixhans guns and rifled guns, which used explosive shells with destructive power against wooden boats.
A 5630-ton broadside battleship, she used massive iron plates sheathed over a wooden hull structure. She was built at Toulon, France.
La Gloire initiated the obsolescence of traditional non-armoured wooden ships-of-the-line, and all major navies had no choice but to build ironclads of their own.
She was soon outclassed however by newer models such as the British Navy's HMS Warrior. Her wooden hull rapidly deteriorated, and she was decommissioned in 1879.
She had two sister ships: Invincible and Normandie, both commissionned in 1862.
