When two or more political parties come together to form a government, it is referred to as a "coalition government". In such a government, each party works together to create a ruling majority and share responsibility for decision-making and governance. Coalition governments are often formed in parliamentary systems where no single party has enough seats to form a government on its own. This type of government allows for a broader range of ideas and perspectives to be represented, but can also face challenges in terms of balancing the interests and agendas of the different parties involved.
