Was Karl Marx a free market theorist?

I attempted to improve the question to read as this: Was Karl Marx a free market philosopher? Some how I could not do it. The answer however is that Marx was not a free market philosopher. He was an economist, political analyst and philosopher that believed the capitalist economic system oppressed the working class. He believed that any remnants of free markets would fall into the hands of capitalists who would destroy itself by frequent depressions. I say this to make it clear that "free markets" could evolve into a socialist economy. Marx believed that only a violent revolution could change the economy.
