Romuald Rajs, nom de guerre "Bury" (30 November 1913 – 30 December 1949), was a Polish soldier, a member of Home Army (AK) and National Military Union (NZW), an anti-communist insurgent and war criminal.

He was sentenced to death in a show trial held by the Polish communist government in 1949, charged with membership in delegalized NZW.

[2][3] In 2005, the Polish Institute of National Remembrance conducted an investigation which revealed that his actions bear the marks of genocide against Orthodox Belarusian community in post-war boundaries of Poland.

Rajs is revered by regional nationalist Polish groups as a hero which creates tensions with the local Belarusian and Eastern Orthodox inhabitants.

A few days later, a groups of soldiers led by Rajs was stopped by Belarusians near Kovel and sent to Bereza Kartuska to lay down their arms and horses.

[5] Returning to Vilnius, he joined a Polish underground resistance movement, and in 1942 he submitted to Lieutenant Gracjan Fróg "Góral" of the National Radical Camp (ONR-Falanga).

In September 1943 he joined the "Goral" partisan group, which from March 1944 was known as the 3rd Brigade of Vilnius Home Army.

At the end of November he joined the communist Polish People's Army, and was assigned to Independent State Forest Protection Battalion and appointed commander of the 2nd Platoon of the 4th Company in Białystok.

In September 1945 Szendzielarz disbanded the brigade, but Rajs decided to continue to fight and made contact with Major Jan Szklarek of the National Military Union (NZW).

[8] In January and February 1946, Rajs' unit "pacified" six Belarusian villages, murdering 79[9]-87[3] civilians and wounding dozens.

[12] In 2002 this case was taken over by the newly formed Institute of National Remembrance (IPN), whose local prosecutor collected evidence which showed that the motivation for the crimes was ethnic hatred.

[13] Rajs remained relatively obscure until his memory was taken over by the National Radical Camp (ONR), a nationalist group, which actively promotes him as a hero.
