The major political changes came from both the american revolution and the french revolution. The american revolution was inspired by the ideas of liberalism developed by thinkers such as John Locke and Montesquieu. This ideas held that the invidividual is more important than the collective, and that every person has rights given by god, which came to be known as human rights. Finally, liberals opposed monarchy and instead favored republicanism, which means that the government should be elected by its people, and could be removed from power in anytime in case it does not satisfy its people's needs.
These ideas inspired the development of constitutions. A constitution is the supreme law of the state, form which all other laws are derived. The first constitution was the United Sates constitution, which defended liberal principles such as freedom of speech, freedom of religion and freedom of assembly. With time, intellectuals in other european countries took insipiration from the US constitution and began to introduce changes in their countries of origin.
The major legal and political changes that contributes to
the rise of constitutional government in the west is most likely because of
consent in which people have given the rights and the equality of which all
people are treated equal. This had brought up big chances in their society.
