The amendments that are made in different countries vary according to the procedures that they have to pass so that they can be enacted in the constitution. Since the amendments can change the entire political system of a nation, it is important for these special procedures to be strict and more stringent than the ones that are required by the legislature. Some of the common examples of amendments are the ones that have been made to the constitution of the United States. For example, the first ten amendments are known as the Bill of rights. The provision for making an amendment in the US constitution is provided in Amendment article V of the constitution. A total of 27 amendments have been made so far in the US constitution.
