[19] His son Jaime Ignacio del Burgo Tajadura[20] was a conservative politician and the Prime Minister of Navarre (president of Diputacion Foral de Navarra) in 1979–1984.

[22] Another of his grandchildren, an entrepreneur Jaime del Burgo Azpíroz,[23] was married to an older sister of Letizia Ortiz, becoming brother-in-law of Felipe VI of Spain[24][25] until their divorce in 2016.

Eliot and W. B. Yeats,[35] also drawing parallels between aetistas and a millenarist Romanian ultra-Right Legion of Archangel Michael;[36] another one points to fascist influence[37] Indeed, the Sorelian thread manifested itself by social radicalism of Del Burgo and a.e.t.

The group departed from orthodox Traditionalist line, commiserating with masses of miserable beings pitted against the politically dominant potentates; they advocated limitation of wealth and regularization of profits.

Contemptuous towards Carlist landowners like José Lamamié and Jaime Chicharro, the students supported Agrarian Reform, obstructed by feudal egoism of the odious grandees of grain.

Strategy of Carlist leaders was denounced as ineffective; in 1934 del Burgo and the young, having declared themselves rebels fed up with legality, accused the old junteros of 3 years of inactivity,[43] their only achievement having been the alliance with caciques and debris of the fallen liberal monarchy.

[57] During the spring he and 14 other Carlists travelled to Italy under the false Peruvian identities; at the Furbara air base they underwent specialist military training, focusing on usage of machine guns and grenades, infantry tactics and urban warfare.

[63] He left Pamplona on July 19; following few days in Rioja, the battalion was moved to Navafria area in Sierra de Guadarrama, in August engaged in heavy fighting for the Somosierra pass.

[76] Some scholars claim that the collaborationists intended to get rid of del Burgo, still active in national AET,[77] and send him abroad, as a Traditionalist tutor of Don Juan.

[78] Late 1937 Fal considered del Burgo a man of trust[79] and included him on the list of potential replacements for the disloyal members of Navarrese junta, sent to the provincial leader Baleztena.

[81] In 1940 Fal appointed him to represent Navarre in a vasco-navarrese junta,[82] though de Burgo's opposition to unification was already burning out and giving way to sense of defeat, resignation and frustration.

[86] When the latter officially raised his claim as Carlos VIII in 1943, del Burgo joined his followers - dubbed carloctavistas - and constructed a supporting dynastical interpretation.

[97] Del Burgo was left without clear dynastical allegiances; over time he developed a critical view of Carlos VIII, considering him "sold out" to Falange.

[101] though in the 1960s it was noted that he "había mostrado inclinación hacia los javieristas"[102] Del Burgo's access to the carloctavista camp made him reconsider his stand versus Francoism, as Don Carlos Pio pursued a decisively collaborationist strategy.

[103] In 1942, during the proceeding fragmentation and bewilderment of Navarrese Carlism,[104] he stood on the carloctavista ticket in local elections to the Pamplona council and was successful, serving as teniende de alcalde until 1944.

[106] The council role did necessarily imply collaboration, but promotion to colonel, 1943 appointment as a provincial Falangist delegate for communication and transport and vice secretary of FET Educación Popular section[107] clearly did, especially that in the mid-1940s he openly started to advocate a possibilist policy.

None of the sources consulted offers any information on a would-be rapprochement (or hostility) between del Burgo and the Javieristas, though his Ideario still served as their doctrinal point of reference.

[113] In 1958 he was appointed as representative of Navarre in the Falangist Consejo Nacional, a largely fictitious executive body which nevertheless automatically guaranteed membership in the Francoist quasi-parliament, Cortes Españolas;[114] it is not clear what if any background mechanism elevated him to the position.

[117] As a former radical aetista and an active collaborationist, he would have seemed a potential ally for the new generation of Carlist progressists, also revolutionary, socially-minded, AET members and apparently keen to exploit possibilist opportunities within Francoism.

[123] He remained at its helm for the next 43 years,[124] presiding over its opening in 1941, removal from Consejo Foral building to "La Agrícola" on Plaza de San Fernando in 1972[125] and re-formatting it from a scholarly institute to the Navarrese public library.

[137] As head of tourism del Burgo promoted the province across Spain, developed the Navarrese section of El Camino de Santiago, drafted Ordenación Turística (1964) for the entire trail[138] and wrote tourist guides related to Navarre.

As an amateur with no systematic training, he did not adhere to any specific methodology,[142] though he remained chiefly within the limits of political history and based his studies on thorough research in primary sources, mostly the printed ones.

[146] Finally, he authored a number of minor publications ranging from petty contributions to popular booklets,[147] like Vida y hechos militares del mariscal de campo Don Juan Manuel Sarasa narrados por él mismo.

[152] This controversy coincides with the fact that del Burgo was personally accused of a war crime,[153] the charge that left him very embittered[154] and which he always denied;[155] it is also disqualified by some historians.

[156] As an amateur he has never assumed academic duties,[157] though he became member-correspondent of Real Academia de la Historia;[158] for his bibliographical work del Burgo received the National Literary Prize in 1967.

[159] Del Burgo commenced his literary career in the early 1930s, publishing short dramas revolving around episodes from the Carlist history and sometimes played at the local party circulos: Lealtad (1932), Cruzados (1934) and Al borde de la traición (1936).

[164] Set in the history of the Civil War, the first two were designed to acclaim patriotic merits and presented a traditional narrative style, though with plots accommodating magical threads;[165] the third one assumed a different tone, infected with bitterness and naturalism.

[168] Though heavily contributing to Carlism in literature, Del Burgo has not made it to the history of Spanish belles-lettres of the 20th century, be it either general synthetic accounts[169] or encyclopedias and dictionaries.
