On May 4-5, 1954, Paraguayan army commander General Alfredo Stroessner led a military coup that forced President Federico Chávez to resign. Stroessner, who controlled both the army and a faction of the ruling Colorado Party, used this power base to depose Chávez and suspend the country's democratic process. Stroessner subsequently ran as the sole candidate in an election and assumed the presidency, beginning a 35-year authoritarian dictatorship marked by suppression of opposition, human rights abuses, and strong U.
S. Cold War-era backing for his anti-communist stance. He remained in power until he was himself overthrown in a coup in February 1989.

Alfredo Stroessner led the military coup that seized power in Paraguay in 1954, deposing President Federico Chávez and later assuming the presidency after an election in which he was the sole candidate.
Stroessner's authoritarian regime lasted 35 years (Britannica's own infobox lists his presidency as 1954-1989); his supporters dominated the legislature and courts, and a large share of the national budget went to paramilitary forces that preserved his authority.
The May 1954 coup was led by Alfredo Stroessner, a career military officer who leveraged his control of both the Colorado Party and the army; President Federico Chávez was forced by Stroessner to resign.

Stroessner's dictatorship was characterized by suppression of opposition parties and labor movements, widespread human rights abuses including arrest, torture, and exile of dissenters, and strong U.S. military and economic support due to his anti-communism, before economic decline in the 1980s led to his overthrow in February 1989 by General Andrés Rodríguez.
Wikipedia's dedicated article on the 1954 Paraguayan coup d'état could not be fetched directly this session (domain returned a cache-only error), so it was not used; instead two independently fetched sources (Britannica and EBSCO Research Starters) were relied on and cross-confirm the core facts (Stroessner-led coup, Chávez forced out, subsequent one-candidate election). Sources agree on the broad narrative; no material disagreement was found between them on the details used here. | Fetched both cited source_urls directly plus Wikipedia's "Alfredo Stroessner" and "1954 Paraguayan coup d'état" articles (both of which load fine now, contrary to the original researcher's note that Wikipedia was unreachable this session).
Facts #1, #3, #4 (Britannica sole-candidate claim; EBSCO "forced...to resign"; EBSCO "suspended the country's democratic process") are genuinely VERIFIED: each "quote" field is an exact, contiguous substring of real text on the cited live page.
Facts #2 and #5 were downgraded VERIFIED -> CHAIN. In both cases the "quote" field is not an actual excerpt from the cited page — it is a paraphrase/stitched composite (using "...") of ideas drawn from different, non-adjacent parts of the source (an infobox date range plus reworded prose for fact #2; two separately-worded sentences for fact #5), presented as if it were a single verbatim quotation. Fabricating quote text is a sourcing-honesty problem even when the underlying claim turns out to be true. I independently confirmed the underlying substance of both facts is accurate via direct fetches of Britannica/EBSCO (e.g., Britannica's Quick Facts do list "president (1954-1989)"; EBSCO does separately state the 1980s economic difficulties and the Feb. 1989 Rodríguez coup, and elsewhere states anti-communism/labor-movement suppression/US military aid), and Wikipedia's "Alfredo Stroessner" article independently and explicitly corroborates every clause with genuine verbatim quotes, so I re-cited these two facts to Wikipedia with real excerpts rather than removing them.
target_leader (Federico Chávez, President of Paraguay) is genuinely VERIFIED against a verbatim Britannica excerpt.
Summary was left unchanged: every claim in it (coup dates, Chávez's forced resignation, Stroessner's army/Colorado Party power base, suspended democratic process, sole-candidate election, 35-year dictatorship, suppression/human-rights-abuses/US anti-communist backing, Feb. 1989 overthrow) still maps to a sourced fact (VERIFIED or CHAIN) after the correction, so no trimming was needed.
