An upper house is a legislative body that exists in many countries around the world. It is often referred to by a variety of synonyms, depending on the specific country and its political system. For example, in the United Kingdom, the upper house is known as the House of Lords, while in the United States it is called the Senate. Other countries use terms such as the Council of States, the Senate of Canada, and the Rajya Sabha. Regardless of what it's called, the upper house of a national legislature is typically responsible for ensuring that the laws created by the lower house are appropriate and fair.
