Since 2007, I have advocated designating May 1 as an international Victims of Communism Day. The May 1 date was not my original idea, but I have probably devoted more time and effort to it than any other commentator. In my view, May 1 is the best possible date for this purpose because it is the day that communists themselves used to celebrate their ideology, and because it is associated with communism as a global phenomenon, not with any particular communist regime, such as that of the USSR or China. However, I have also long recognized that it might make sense to adapt another date for Victims of Communism Day, if it turns out that some other date can attract a broader consensus behind it. The best should not be the enemy of the good.

As detailed in my May 1 post this year, November 7 is probably the best such alternative, and in recent years it has begun to attract considerable support. Unlike May 1, this choice is unlikely to be contested by trade unionists and other devotees of the pre-communist May 1 holiday. While I remain unpersuaded by their objections on substantive grounds, pragmatic considerations suggest that an alternative date is worth considering, if it can sidestep this debate, and thereby attract broader support.

For that reason, I am doing a Victims of Communism Day post today, in addition to the one I did on May 1. If November 7 continues to attract more support, I may eventually switch to that date exclusively. But I reserve the options of returning to an exclusive focus on May 1, doing annual posts on both days, or switching to some third possibility should there be an other date that attracts a broader consensus than either May 1 or November 7.

In addition to its growing popularity, November 7 is a worthy alternative because it is the anniversary of the day that the very first communist regime was established in Russia. All subsequent communist regimes were at least in large part inspired by it, and modeled many of their institutions and policies on the Soviet precedent.

The Soviet Union did not have the highest death toll of any communist regime. That dubious distinction belongs to the People's Republic of China. North Korea probably surpassed the USSR in the sheer extent of totalitarian control over everyday life. Pol Pot's Cambodia may have surpassed it in terms of the degree of sadistic cruelty and torture practiced by the regime, though this is admittedly a very difficult thing to measure. But all of these tyrannies—and more – were at least in part variations on the Soviet original.

Having explained why November 7 is worthy of consideration as an alternative date, it only remains to remind readers of the more general case for having a Victims of Communism Day. The following is adopted from this year's May 1 Victims of Communism Day post, and some of its predecessors:

The Black Book of Communism estimates the total number of victims of communist regimes at 80 to 100 million dead, greater than that caused by all other twentieth century tyrannies combined. We appropriately have a Holocaust Memorial Day. It is equally appropriate to commemorate the victims of the twentieth century's other great totalitarian tyranny.

Our comparative neglect of communist crimes has serious costs. Victims of Communism Day can serve the dual purpose of appropriately commemorating the millions of victims, and diminishing the likelihood that such atrocities will recur. Just as Holocaust Memorial Day and other similar events promote awareness of the dangers of racism, anti-Semitism, and radical nationalism, so Victims of Communism Day can increase awareness of the dangers of left-wing forms of totalitarianism, and government domination of the economy and civil society.

While communism is most closely associated with Russia, where the first communist regime was established, it had equally horrendous effects in other nations around the world. The highest death toll for a communist regime was not in Russia, but in China. Mao Zedong's Great Leap Forward was likely the biggest episode of mass murder in the entire history of the world.

November 7, 2017 was the 100th anniversary of the Bolshevik seizure of power in Russia, which led to the establishment of the first-ever communist regime. On that day, I put up a post outlining some of the lessons to be learned from a century of experience with communism. The post explains why most of the horrors perpetrated by communist regimes were intrinsic elements of the system. For the most part, they cannot be ascribed to circumstantial factors, such as flawed individual leaders, peculiarities of Russian and Chinese culture, or the absence of democracy. The latter probably did make the situation worse than it might have been otherwise. But, for reasons I explained in the same post, some form of dictatorship or oligarchy is probably inevitable in a socialist economic system in which the government controls all or nearly all of the economy.

While the influence of communist ideology has declined since its mid-twentieth century peak, it is far from dead. Largely unreformed communist regimes remain in power in Cuba and North Korea. In Venezuela, the Marxist government's socialist policies have resulted in political repression, the starvation of children, and a massive refugee crisis—the biggest in the history of the Western hemisphere. The regime continues to hold on to power by means of repression, despite growing international and domestic opposition.

In Russia, the authoritarian regime of former KGB Colonel Vladimir Putin has embarked on a wholesale whitewashing of communism's historical record. In China, the Communist Party remains in power (albeit after having abandoned many of its previous socialist economic policies), and has recently become less tolerant of criticism of the mass murders of the Mao era (part of a more general turn towards greater repression).

In sum, we need Victims of Communism Day because we have never given sufficient recognition to the victims of the modern world's most murderous ideology or come close to fully appreciating the lessons of this awful era in world history. In addition, that ideology, and variants thereof, still have a substantial number of adherents in many parts of the world, and still retains considerable intellectual respectability even among many who do not actually endorse it. Just as Holocaust Memorial Day serves as a bulwark against the reemergence of fascism, so this day of observance can help guard against the return to favor of the only ideology with an even greater number of victims.
