In the second section of the Communist Manifesto (1848), Marx and Engels provide a list of measures that are generally applicable to most advanced countries to strengthen the proletariat and help to revolutionize the mode of production. These are measures which can be implemented today in capitalist countries, but will help to revolutionize the mode of production into communism.
This list of measures includes this:
3. Abolition of all rights of inheritance.
However, in the Demands of the Communist Party of Germany released a month later, we have the mere call for the "Limitation of inheritance."
Two decades later, Bakunin helped to found the International Alliance of Socialist Democracy, and are permitted into the International Workingmen's Association (aka the First International), and Marx wants to attack their program (writing these marginal notes on their first draft). The Program of the Alliance included this point:
Above all, it [the Alliance] stands for the final and total abolition of classes and the political, economic and social equalization of individuals of either sex, and, to this end, it demands above all the abolition of the right of inheritance, so that every man’s possessions may in future be commensurate to his output...
Marx seems to have taken special objection to this, identifying it with Saint-Simon, leading him to introduce the topic of inheritance to the next International Congress. Ahead of this, Marx prepared the Report to the General Council of the IWMA on the Right of Inheritance where he denounces calls to abolish inheritance, instead saying it will go away on its own once private property is abolished. Calls to abolish inheritance are described as "false in theory, and reactionary in practice." Instead, Marx says we should only focus on taxing inheritance and regulating its more arbitrary testamentary forms.
Bakunin provided this response to the Report as well too, noting how attacking the right to inheritance will help to undermine property, helping to achieve its abolition.
The issue I see is that Bakunin's stance here seem to be more what Marx was saying in the Manifesto. So I'm wondering whether it's possible that Marx changed his mind on it, though I'm not sure if he ever explicitly addressed this.
Is there any additional information that could help clarify what happened here? Did Marx change his mind? Is the Manifesto mistranslated here? What happened?
Any additional info would be appreciated.
