The main consequence of the English Bill of Rights in 1689 was the establishment of constitutional monarchy in England. By limiting the powers of the monarchy and asserting the rights of Parliament, it marked a crucial step towards modern democracy. The Bill outlined specific rights, such as freedom of speech in parliamentary debates and protections against excessive bail and cruel punishment. It ensured that the monarchy could not circumvent the law or govern without the consent of Parliament, fostering an environment where civil liberties could flourish and government accountability was prioritized.
