Until 1973, there was no known ban or restriction on LGBTIQ+ people serving in the military of Uruguay.

The age of consent in Uruguay is 15 years old regardless of the type of intercourse.

Homosexual activity is legal according to the Uruguay Penal Code.

During the Nazi regime, transgender people were targeted repeatedly and were de facto criminalised under Paragraphs 175 and 183, which were used to prosecute people for homosexuality or cross-dressing. Previously respected "transvestite passes" which exempted trans people from Paragraph 183 were promptly ignored and revoked. Trans people would also be targeted in the Holocaust although they were often grouped as gay men, leaving the death toll of trans victims unknown. However some trans people could avoid the worst of Nazi persecution provided they were not Jewish and weren't considered homosexual (which was based on the assumption of an attraction to the birth sex they were assigned as). An example includes a transgender lesbian known as R. who was considered to be Aryan, non-homosexual and a good worker by the Nazis and got arrested in 1938 but released two years later under the assumption she would detransition. However she did not and was then forced to undergo conversion therapy until her death in 1943. After the fall of the Nazis, Germany did not grant legal gender recognition until 1980.

With the rise of the Nazi regime, transgender healthcare was banned, and the Berlin Institute for Sexual Science was closed and destroyed, it was the only institute offering gender-affirming care.

Under Portugal’s Estado Novo dictatorship (1933–1974), LGBT people faced systematic legal and social repression. While some laws predated the regime, the dictatorship expanded and enforced them strictly. In 1852, the Penal Code criminalized “offense against modesty,” indirectly targeting homosexual acts with prison terms or fines. In 1912, homosexuality was explicitly penalized under laws against “vices against nature,” punishable with up to one year in prison and sometimes enforced “re-education” in labor colonies or correctional houses. With the Estado Novo’s rise, repression intensified. In 1936, Decree-Law No. 26 643 created the “state of delinquency,” which allowed the authorities to punish homosexual behavior even without a proven criminal act. Special detention centers and labor colonies were established, with sentences ranging from one to six years. During the 1940s and 1950s, police surveillance intensified, targeting cruising areas in public spaces, and arrests were socially selective, focusing on lower-class individuals while elites often escaped scrutiny. The 1954 Penal Code (Decree-Law No. 39 688) explicitly criminalized homosexuality, applying “security measures” such as confinement in asylums or labor houses and probation. Over 12,000 people were admitted to such institutions between 1933 and 1951. Political repression also leveraged these laws; for example, in 1962, the politician Júlio Fogaça was convicted for homosexual conduct. Despite some softening of social surveillance in the late 1960s, repression continued until the dictatorship’s fall. The Estado Novo ended with the Carnation Revolution on 25 April 1974, which brought an immediate decline in political policing of LGBT people. However, the legal framework criminalizing homosexuality remained until 1982. The Penal Code reform, effective in January 1983, finally decriminalized consensual same-sex relations between adults in private, marking the official end of Estado Novo-era legal repression.

The Faroe Islands ended criminalisation of homosexuality in 1933.
