Girolamo Carafa (or Caraffa), Marquis of Montenegro (Abruzzo, 1564 – Genoa, 1633) was a general in Spanish and Imperial service from Italian descent.
But in 1597, he participated in the Siege of Amiens, where he became leader of the besieged Spanish troops, when General Porto-Carrero was killed.
Here he was contacted by Ferdinand II, Holy Roman Emperor and entered in his service at the outbreak of the Thirty Years' War.
He played an important role in the victory at the Battle of White Mountain, when he prevented the union of the troops of Gábor Bethlen with his Bohemian allies.
After the peace treaty with Gábor Bethlen was signed, Girolamo became Imperial Field Marshal and Reichsfürst.
