 * Croatian partisans known as "Crusaders" fought until eradicated in the early 1950s.
 * Albanian partisans (members of the Balli Kombëtar and supporters of the king Zog I) fought until eradicated in the early 1950s.

In Poland
The 'cursed soldiers' (Polish: Żołnierze wyklęci) is a name applied to a variety of Polish resistance movements that were formed in the later stages of World War II and afterwards. Created by former members of the Polish underground resistance organizations of World War II, these organizations continued the struggle against the pro-Soviet government of Poland well into the 1950s. Most of these anti-communist groups ceased operations in the late 1940s or 1950s. However, the last known 'cursed soldier', Józef Franczak, was killed in an ambush as late as 1963, almost 20 years after the Soviet take-over of Poland.

In the Baltic States
The Forest Brothers (also: Brothers of the Forest, Forest Brethren; Forest Brotherhood; Estonian: metsavennad, Latvian: meža brāļi, Lithuanian: miško broliai) were Estonian, Latvian, and Lithuanian partisans who waged guerrilla warfare against Soviet rule during the Soviet invasion and occupation of the three Baltic states during, and after, World War II.

The Soviet Army occupied the independent Baltic states in 1940–1941 and, after a period of German occupation, again in 1944–1945. As Stalinist repression intensified over the following years, 50,000 residents of these countries used the heavily-forested countryside as a natural refuge and base for armed anti-Soviet resistance.

Resistance units varied in size and composition, ranging from individually operating guerrillas, armed primarily for self-defense, to large and well-organized groups able to engage significant Soviet forces in battle.

In Romania
An armed resistance movement against the communist regime in Romania was active from the late 40s to the mid 50s, with isolated individual fighters remaining at large until the early 1960s (Frontul Salvarii Nationale was active until after the revolution of 1989). Armed resistance was the first and most structured form of resistance against the communist regime. It wasn’t until the overthrow of Nicolae Ceauşescu in 1989 that details about what was called “anti-communist armed resistance” were made public. It was only then that the public learnt about the several small armed groups(there was large groups,from 1947 to 1958 the number of partisans was maintained at 20.000,large losses was constant but the number of partizan remains the same,the number drops after 1958,the partisan activity has decresead from 1958 to 1965,several cells remained active until 1989), which sometimes termed themselves "haiducs", that had taken refuge in the Carpathian Mountains, where some hid for ten years from authorities.
