The Francs-Tireurs et Partisans Français (FTPF), or commonly the Francs-Tireurs et Partisans (FTP), was an armed resistance organization created by leaders of the French Communist Party during World War II (1939–45).
 The communist party was neutral at first, following the Soviet Union's official view that the war was a struggle between imperialists, but changed to a policy of armed resistance to the German occupation of France after the end of the Soviet-German alliance, when Germany invaded the Soviet Union in June 1941.
 Three groups were formed, consisting of party members, young communists and foreign workers.
 Early in 1942 they were merged to form the FTP, which undertook sabotage and assassinations of the occupation.
 The FTP became the best organized and most effective of the French Resistance groups.
 In March 1944, before the Allied forces returned to Normandy, the FTP was theoretically merged with the other Resistance groups.
 In practice, it retained its independence until the end of the war.
The Guerrilla war in the Baltic states or the Forest Brothers resistance movement was the armed struggle against Soviet rule that spanned from 1944 to the mid-1950s.
 After the occupation of the Baltic territories by the Soviets in 1944, an insurgency started.
 According to some estimates, 10,000 partisans in Estonia, 10,000 partisans in Latvia and 30,000 partisans in Lithuania and many more supporters were involved.
 This war continued as an organised struggle until 1956 when the superiority of the Soviet military caused the native population to adopt other forms of resistance.
 While estimates related to the extent of partisan movement vary, but there seems to be a consensus among researchers that by international standards, the Baltic guerrilla movements were extensive.
 Proportionally, the partisan movement in the post-war Baltic states was of a similar size as the Viet Cong movement in South Vietnam.
Pēteris Dzelzītis (September 21, 1921 – February 16, 1948) was a Latvian soldier.

Renda (German: "Rönnen" ) is a village located in Renda parish in the northeast section of the Kuldīga municipality of western Latvia.

The Rev. Dr. Yanis Alfred Smits, commonly known as Bishop Smits, is a Latvian theologian and Baptist pastor.
 He was persecuted for his political and religious activism against the Soviet rule over Latvia during 1956-1976.

 He would eventually be elected as Bishop of the Latvian Baptist Union.
The Forest Brothers (also Brothers of the Forest, Forest Brethren, or Forest Brotherhood; Estonian: "metsavennad" , Latvian: "meža brāļi" , Lithuanian: "miško broliai" ) were Estonian, Latvian, and Lithuanian partisans who waged a guerrilla war against Soviet rule during the Soviet invasion and occupation of the three Baltic states during, and after, World War II.

The Lithuanian Freedom Army (Lithuanian: "Lietuvos laisvės armija" or LLA) was a Lithuanian underground organization established by Kazys Veverskis (codename Senis), a student at Vilnius University, on December 13, 1941.
 Its goal were to re-establish independent Lithuania via political and military means.
 During the Nazi Germany occupation it opposed German policies, but did not begin armed resistance.
 The armed struggle began in mid-1944 when Red Army reached the Lithuanian borders after the Minsk Offensive.
 The LLA became the first wave of the Lithuanian partisans, armed anti-Soviet guerrilla fighters.
 It attempted to become the central command of the armed struggle.
 However, the organization was liquidated by the Soviet security forces (NKVD and KGB) by April 1946.
 The remnants of the organization were absorbed by other partisans.
 The guerrilla war continued until 1953.
The Lithuanian partisans (Lithuanian: "Lietuvos partizanai" ) were partisans who waged a guerrilla warfare in Lithuania against the Soviet Union in 1944–1953.
 Similar anti-Soviet resistance groups, also known as Forest Brothers and cursed soldiers, fought against Soviet rule in Estonia, Latvia, Poland, Romania and Galicia.
 It is estimated that a total of 30,000 Lithuanian partisans and their supporters were killed.
