Legislatures are the backbone of democratic systems, serving as law-making bodies and representing diverse constituencies. They draft and pass laws, oversee the executive branch, approve budgets, and ratify treaties. Legislatures also provide a forum for public debate and confirm key appointments. Different types of legislative systems exist worldwide, including unicameral and bicameral structures. These systems operate within presidential, parliamentary, or hybrid frameworks, each with unique power dynamics between the executive and legislative branches.
