What Under which type of government did all American colonists originally live?

All American colonists originally lived under a colonial system governed by British monarchy and imperial rule. Each colony was established with its own charter, often granting a degree of self-governance, but they were ultimately subject to the authority of the British Crown. This system included appointed governors and colonial assemblies, which allowed for some local decision-making while still being under British control. The desire for greater autonomy and self-governance eventually contributed to the American Revolution.
