1. Man in the Iron Mask (1640 - 1703)

With an HPI of 71.39, Man in the Iron Mask is the most famous Italian Extremist. His biography has been translated into 36 different languages on wikipedia.

The Man in the Iron Mask (French: L'Homme au Masque de Fer; died 19 November 1703) was an unidentified prisoner of state during the reign of King Louis XIV of France (1643–1715). Warranted for arrest on 28 July 1669 under the pseudonym of "Eustache Dauger", he was incarcerated on 24 August and held for 34 years in the custody of the same jailer, Bénigne Dauvergne de Saint-Mars, in four successive French prisons, including the Bastille. When he died there on 19 November 1703, his inhumation certificate bore the pseudonym of "Marchioly", leading several 19th century historians to conclude the prisoner was Italian diplomat Ercole Antonio Mattioli. His true identity remains a mystery, even though it has been extensively debated by historians, and various theories have been expounded in numerous books, articles, poems, plays, and films. Among the oldest theories is one proposed by the French philosopher and writer Voltaire, who claimed in the second edition of his Questions sur l'Encyclopédie (1771) that the prisoner was an older, illegitimate brother of Louis XIV. This assertion of a royal connection was echoed later by authors who proposed variants of this aristocratic solution. What little is known about the prisoner is based on contemporary documents that surfaced during the 19th century, mainly some of the correspondence between Saint-Mars and his superiors, in which the prisoner had been labelled "only a valet" shortly after his arrest. What emerges from these documents is that he was jailed for "what he had seen", "what he knew", and "what he was employed to do" before his arrest. Legend has it that no one ever saw his face, as it was hidden by a mask of black velvet cloth, later misreported by Voltaire as an iron mask. Official documents reveal, however, that the prisoner was made to cover his face only when travelling between prisons after 1687, or when going to prayers within the Bastille in the final years of his incarceration; modern historians believe the latter measure was imposed by Saint-Mars solely to increase his own prestige at the end of his career, thus causing persistent rumours to circulate about this seemingly important prisoner. In 1932, French historian Maurice Duvivier proposed that the prisoner was Eustache Dauger de Cavoye, a nobleman associated with several political scandals of the late 17th century. This solution, however, was disproved in 1953 when previously unpublished family letters were discovered by another French historian, Georges Mongrédien, who concluded that the enigma remained unsolved owing to the lack of reliable historical documents about the prisoner's identity and the cause of his long incarceration. The Man in the Iron Mask has been the subject of many works of fiction, most prominently in 1850 by Alexandre Dumas. A section of his novel The Vicomte of Bragelonne: Ten Years Later—the final installment of his D'Artagnan saga—features this prisoner, portrayed as Louis XIV's identical twin and forced to wear an iron mask. In 1840, Dumas had first presented a review of the popular theories about the prisoner extant in his time in the chapter "L'homme au masque de fer", published in the eighth volume of his non-fiction Crimes Célèbres. This approach was adopted by many subsequent authors, and speculative works have continued to appear on the subject.

2. Charles Ponzi (1882 - 1949)

With an HPI of 67.29, Charles Ponzi is the 2nd most famous Italian Extremist. His biography has been translated into 35 different languages.

Charles Ponzi (, Italian: [ˈpontsi]; born Carlo Pietro Giovanni Guglielmo Tebaldo Ponzi; March 3, 1882 – January 18, 1949) was an Italian swindler and con artist who operated in the U.S. and Canada. His aliases included Charles Ponci, Carlo, and Charles P. Bianchi.Born in Lugo, Italy, he became known in the early 1920s as a swindler in North America for his money-making scheme. He promised clients a 50% profit within 45 days or 100% profit within 90 days, by buying discounted postal reply coupons in other countries and redeeming them at face value in the U.S. as a form of arbitrage.: 1 In reality, Ponzi was paying earlier investors using the investments of later investors. While this type of fraudulent investment scheme was not invented by Ponzi, it became so identified with him that it now is referred to as a "Ponzi scheme". His scheme ran for over a year before it collapsed, costing his "investors" $20 million. Ponzi may have been inspired by the scheme of William W. Miller (also known as "520% Miller"), a Brooklyn book-keeper who in 1899 used a similar deception to take in $1 million (approximately $35 million in 2022).
