A Unified Government occurs when one political party controls both the executive branch and the legislative branch of a government. This means that the same party holds the presidency and the majority in the legislature, allowing for more streamlined decision-making and policy implementation. In contrast to a divided government, where different parties control these branches, a unified government can lead to quicker passage of laws and a more cohesive political agenda. This structure is often seen in systems like the United States, where the party in power can more easily enact its platform and respond to issues facing the nation.
