A system in which two or more political parties form the government is called a coalition. This means that these political parties come together to form a government and work together to achieve their goals. In a coalition system, no single party has enough seats in the legislature to form a government on its own, so multiple parties must work together to create a governing coalition. This is often done to achieve a more stable government or to represent a broader range of interests and perspectives.
