Lenin’s regime was like an earthquake that set off deep fears within the middle and upper classes of the world, so that for the next 72 years, the Soviet Union remained the bogeyman that every union leader, activist and politician outside Russia could use, for good or ill.
Internationally, Lenin broke almost all the rules. He signed a peace treaty with Germany, effectively bowing out of World War I. More importantly, his government repudiated all foreign debt contract by previous governments or by any Russian entity.
Internally, the new government nationalized all private property — this meant all income-producing property, not personal possessions (clothes, furniture, etc.) and not personal real estate of middle-income people or below. In addition, it nationalized all banks, factories and all business and luxurious property and expropriated all Church property. Wages were raised and the eight-hour working day was introduced. Only agriculture remained initially untouched. Lastly, the Tsar and his family, were executed in July 1918.
The effect of all these measures was electrifying. The Russian revolt inspired a surge by the world Communist movement, which was more or less aligned with the Bolsheviks. In 1918-19 a revolution broke out in Germany, where a short-lived Bavarian Soviet Republic popped up. Next door, in Hungary, there were a series of 1918-1920 revolts with heavy Communist involvement. Similarly in Italy, the “biennio rosso” (red biennium) of social conflict between 1919 and 1920 included mass strikes, worker protests and self-management experiments in land and factories seizures by peasants and workers.
For about two years, the western Allies briefly occupied militarily parts of what would soon be called the Soviet Union, until the Reds won the Civil War. In 1922, with the Russian economy near collapse, Lenin reversed course and made a feint to “state capitalism” under his New Economic Policy, which won his government diplomatic recognition in Europe, although the USA would withhold it until 1933.
