What would happen if the thirteen colonies were never united?

If the thirteen colonies had never united, they likely would have remained fragmented and vulnerable to external threats, particularly from European powers like Britain and France. This disunity could have hindered their ability to effectively resist British policies and military actions, leading to a prolonged period of colonial unrest or even the possibility of some colonies being reabsorbed by Britain. Economically and politically, the lack of a unified front would have stunted their development and could have resulted in a series of isolated regional conflicts rather than a collective pursuit of independence. This scenario might have delayed or entirely altered the trajectory of the future United States.
