A lower house refers to the chamber or assembly that forms part of a bicameral legislative body. It typically represents the population directly and has different functions depending on the political system of the country.
In some countries, the lower house is responsible for proposing and passing legislation, while in others, it focuses on important matters like budgetary decisions, initiating impeachments, or approving treaties.
The term "lower house" can also be used more broadly to describe any legislative body that holds less power or authority compared to an upper house.
