A "party system" in political studies refers to the organizational structure and dynamics of political parties within a given political context. It categorizes how parties interact, compete for power, and influence governance. Party systems can be classified as single-party, two-party, or multi-party systems, with each type presenting different implications for governance and democratic participation. In a multi-party system, for instance, diverse views can be represented, but may lead to challenges in forming stable coalitions. Conversely, a two-party system often simplifies electoral choices and promotes clear governmental accountability.
