The flag of the Byelorussian SSR was adopted by decree on 25 December 1951. The flag was slightly modified in 1956 when construction details were added for the red star and the golden hammer and sickle. The final specifications of the flag was set in Article 120 of the Constitution of the Byelorussian SSR and are very similar to the current Belarusian flag. The flag had a length-to-width ratio of one to two (1:2), just like the flag of the Soviet Union (and the other fourteen union republics). The main portion of the flag was red (representing the Revolution), with the rest being green (representing the Belarusian forests). A pattern of white drawn on red decorated the hoist portion of the flag; this design is often used on Belarusian traditional costumes. In the upper corner of the flag, in the red portion, a gold hammer and sickle was added, with a red star outlined in gold above it. The hammer represented the worker, and the sickle the peasant; according to Soviet ideology, these two symbols crossed together symbolised co-operation between the two classes. The red star, a symbol commonly used by Communist parties, was said to stand either for the five social groups (workers, youth, peasants, military, and academics), the five known continents, or the five fingers of the worker's hand. The hammer, sickle and star were sometimes not displayed on the reverse of the flag. The purpose for this design was that the Byelorussian SSR, along with the Soviet Union and the Ukrainian SSR, were admitted to the United Nations in 1945 as founding members and needed distinct flags for each other. The designer of the flag was Mikhail Gusyev.
