In the highly centralized, one-party-ruled Soviet Union (USSR) ethnic, religious and linguistic differences were played down and even suppressed. Accordingly, the flags of the Soviet republics were designed not to look too distinct from each other and not to be too heavily rooted in the history and culture of each republic.
In 1947, the Supreme Soviet of the USSR recommended that the Union’s republics adopt national flags. The constituent republics adopted such flags in the years 1950-1954. The design of all these flags adhered strictly to guidelines laid down by central authorities. So, in the end, the flags of the Soviet republics became quite similar to that of the Soviet Union.
Like the flag of the USSR, a red flag with a golden hammer and sickle emblem under a gold-bordered red star, the flags of the republics were also predominantly red. All but one, they had the star, hammer and sickle in gold; only on the flag of the Georgian SSR the emblem was red, on a blue sun with red rays. The distinguishing features of these flags were vertical and horizontal stripes or wavy lines in the colours blue, green and white. To an untrained eye, the flags of the Soviet republics looked remarkably alike.
National, cultural and historical references in the flag designs were kept at a minimum. So, for example, the flag of the Belorussian SSR had a vertical stripe of a traditional pattern at the hoist. The Usbek, Kazakh, Kyrgyz, Turkmen and Azerbaijani Soviet republics had a stripe of blue or sky blue, a colour traditionally representing Turkic peoples. The red-white-green in the flag of the Tajik SSR are the Pan-Iranian colours, but the colours were also ment to stand for Tajikistan’s agriculture and cotton production.
At the time of the dissolution of the Soviet Union in 1991 there were 15 republics. Today, only two of the now independent former USSR republics use the old flags: Transnistria, officially the Pridnestrovian Moldavian Republic, refused to leave the Soviet Union together with the majority of the Moldavian SSR, now Moldova, and 25 years later this small strip of land is a mostly unrecognized republic which uses exactly the same flag as the Moldovan SSR. The present flag of Belarus is a slight modification of the flag of the Belarussian SSR.
In the heyday of the USSR, the flags of the Soviet republics were on the album covers of several different singles, EPs and LPs with recordings of the national anthem of the Soviet Union and oftentimes also the anthems of the 15 republics and the international Socialist anthem The Internationale. They were released from Melodiya (Μелодия), the major state-owned record label of the USSR.
On the cover in the picture, the 15 flags are arranged in rows of three. From left to right, beginning with the largest of the Soviet republics, 1: The Russian SFSR, the Ukrainian SSR, the Belarussian SSR. 2: The Uzbek SSR, the Kazakh SSR, the Georgian SSR. 3: The Lithuanian SSR, the Azerbaijani SSR, the Moldavian SSR. 4: The Kyrgyz SSR, the Latvian SSR, the Tajik SSR. 5: The Armenian SSR, the Turkmen SSR, the Estonian SSR.
On the albums with national anthems were typically also the Soviet Union’s state coat of arms with the Communist red star and the hammer and sickle over the globe and the rising sun. The emblem was surrounded by a wreath of wheat and a red ribbon with the Union’s motto in Russian and the other official languages of its constituent republics: “Workers of the world, unite!”.
