The british government allowed the colonists complete control of domestic and foreign affairs?

Of course he did not, and that was the main reason why the War of Independence happened. At first the colonists were negotiating the possibility of having control of their colonies by means of assemblies, and of being able to trade freely between them and with England, but the British Crown would not allow it, and facts like the Boston Massacre, act that the British empire did in retaliation against the Colonists; led to think that only war would be the solution for both politics and trade, were freely decided by the inhabitants of the 13 Colonies.
