What are some of the recent examples of a violent large-scale redistribution of wealth?
Let us first ask ourselves, what is the wealth that can be redistributed?
Violent redistributing of consumer goods is called "looting" and it has always accompanied civil unrest; I don't think you are asking about that.
Redistribution of capital, AKA, means of production, often, indeed, accompanies revolutions.
When applied to industrial enterprise this redistribution usually takes form of nationalization (which rarely is accompanied by giving away shares to the poor), so, again, it does not fit your question.
When applied to agricultural capital, this means Land reform, and it does usually mean that the poor peasants become land owners.
E.g., the Romanian Revolution lead to a land reform, redistributing the land wealth from the government bureaucracy to the peasants.
