Jean Gilbert Victor Fialin, duc de Persigny

Jean-Gilbert-Victor Fialin, duc de Persigny (11 January 1808 – 12 January 1872) was a diplomat and statesman of the Second French Empire.

Fialin was born at Saint-Germain-Lespinasse in the Loire, where his father was Receiver of Taxes, and was educated at Limoges. He entered Saumur Cavalry School in 1826, becoming Maréchal des logis in the 4th Hussars two years later. The role played by his regiment in the July Revolution of 1830 was regarded as insubordination, resulting in Fialin being dismissed from the army. He then became a journalist, and after 1833, a strong Bonapartist, assuming the style vicomte de Persigny, said to be dormant in his family.
