What is the name given to the government in which a congress is controlled by one party and the executive branch is controlled by the other party?

The situation where the legislative branch (congress) is controlled by one political party while the executive branch is led by another is known as "divided government." This scenario often leads to political gridlock, as differing agendas can make it challenging to pass legislation. Divided government is common in systems with checks and balances, such as the United States.
