Red flag (politics) in the context of "Flag of the Soviet Union"

Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–750 nanometers. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy.

Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought the introduction of the first synthetic red dyes, which replaced the traditional dyes. Red became a symbolic color of communism and socialism; Soviet Russia adopted a red flag following the Bolshevik Revolution in 1917. The Soviet red banner would subsequently be used throughout the entire history of the Soviet Union. China adopted its own red flag following the Chinese Communist Revolution. A red flag was also adopted by North Vietnam in 1954, and by all of Vietnam in 1975.

Sovietization (Russian: советизация, romanized: sovyetizatsiya [səvʲɪtʲɪˈzat͡sɨjə]) is the adoption of a political system based on the model of soviets (workers' councils) or the adoption of a way of life, mentality, and culture modeled after the Soviet Union.

A notable wave of Sovietization (in the second meaning) occurred during the Russian Civil War in the territories captured by the Red Army. Later, the territories occupied by the Russian SFSR and the USSR were Sovietized. Mongolia was conquered by the Soviet Union and Sovietized in the 1920s, and after the end of the Second World War, Sovietization took place in the countries of the Soviet Bloc (Eastern and Central Europe: Czechoslovakia, East Germany, Hungary, Poland, the Baltic states, etc.). In a broad sense, it included the creation of Soviet-style authorities, new elections held by Bolshevik party members with opposition parties being restricted, the nationalization of private land and property, and the repression against representatives of "class enemies" (kulaks, or osadniks, for instance). Mass executions and imprisoning in Gulag labor camps and exile settlements often accompany that process. This was usually promoted and sped up by propaganda aimed at creating a common way of life in all states within the Soviet sphere of influence. In modern history, Sovietization refers to the copying of models of Soviet life (the cult of the leader's personality, collectivist ideology, mandatory participation in propaganda activities, etc.).
