In the early hours of August 1, 1956, a group of Liberal Party supporters and university students, backed by military elements and aided by Major Santos Sorto Paz — commander of the Cuartel San Francisco barracks in Tegucigalpa — seized the barracks in an uprising against President Julio Lozano Díaz, who had held power since declaring himself interim president after the disputed 1954 election. Government forces quickly suppressed the revolt, inflicting what one Honduran academic source calls "a considerable toll of dead and wounded." Lozano Díaz survived the attempt and pushed through a disputed October 7, 1956 congressional election that opposition parties denounced as fraudulent, but his government proved short-lived: on October 21, 1956 a separate military faction led by General Roque J.
Rodríguez ousted him and installed a military junta. The Liberal Party later honored the August 1 participants as "martyrs and heroes," and the newspaper El Pueblo ran a commemorative edition on the incident's second anniversary in 1958.

Lozano Díaz was ultimately removed less than three months later: after the opposition parties declared the 7 October 1956 election fraudulent, military leaders 'brought down the Lozano Díaz dictatorship and established a military junta' on October 21, 1956, led by General Roque J. Rodríguez.

Editorial Note
Multiple independent sources (an encyclopedia entry, a UNAH academic history document, and two La Tribuna newspaper pieces) converge on the same date, location, and broad character of this event, giving confidence it matches the Cline Center's 1956-08-01 Honduras record. However, precise operational details (numbers of insurgents, exact casualty counts, hour-by-hour timeline, number of detentions) vary across secondary compilations of uncertain editorial reliability (e.g., one independent web compilation cites "approximately 400 insurgents," "more than a hundred dead or wounded," and "130 suspects detained," attributing this to a 1997 El Heraldo article by historian Mario R. Argueta drawing on John D. Martz's 1959 book "Central America: The Crisis and the Challenge"). I could not access either the 1997 Argueta article or the Martz book directly this session, so those specific figures were omitted rather than reported as verified; the UNAH academic source's more general "considerable toll of dead and wounded" was used instead. Sources also differ slightly in emphasis: the Spanish Wikipedia article on Cuartel San Francisco (a map, not cited as a source here) frames the event as "Santos Sorto Paz's uprising," while La Tribuna and the UNAH document frame it more as a Liberal Party/student action that a sympathetic barracks commander (Sorto Paz) enabled — consistent with the Cline Center's "military coup" coding given the direct military commander involvement, but with substantial civilian/party participation. The Wikipedia English-language article "1956 Honduran coup d'état" (and the related "Honduran military junta of 1956–1957" article) covers only the successful October 21, 1956 coup and was used only to identify search leads, not as a cited source; all facts above were confirmed against independently fetched sources rather than against Wikipedia text itself. | All 4 source URLs were live and fetched successfully; all 6 quotes attributed to them were verbatim or fair-ellipsis matches of actual page content (encyclopedia.com Lozano Díaz entry by Michael A. Polushin; La Tribuna 2010 "Los liberales sí han apoyado..."; UNAH-hosted Rojas Bolaños "De la posguerra a la crisis"; La Tribuna 2021 "El golpe de Estado de 1956"). Author attribution (Polushin) and publication title (Encyclopedia of Latin American History and Culture) were independently confirmed on the page. Target_leader claim (interim president since Nov 1954, after disputed 1954 election) is directly supported by the same encyclopedia.com page. Only issue found: the summary asserted the October 21, 1956 coup was "bloodless," a detail not present in, or supported by, any of the six sourced facts or their underlying quotes — this word was trimmed per the strict verification standard. The entry's own "notes" field is appropriately conservative, explicitly declining to report unverifiable casualty/detention figures (400 insurgents, 130 detained) that it could not source directly, which supports the overall honesty of the sourcing methodology.
Cross-Reference
Datasets agree. At least two of the three reference datasets we check against carry this event, and none of them disagrees about its date or its result.
Identifiers for finding this same event in the other datasets:
Coup Atlas research identifies the target as: Julio Lozano Díaz, de facto/interim President of Honduras (in power since November 1954).
Baseline coding: Coup attempt failed to remove the incumbent. Recorded leader fate: remained in office; not physically harmed. The baseline file does not name individual targets; researched names are kept in a separate layer.
