The colonial governments while they were under British rule didn't have any representation in the British government. They were able to have a say in matters that had to do with where they lived, but on a large scale, Parliament wouldn't listen to them. Hope this helps! Please let me know if I'm wrong.
The group that benefited the most from gaining independence from Mexico are the Tejanos who were the former Americans and has now become the American citizens and had claimed for the American rights and privileges.
