This study examines the relationship between the number and type of political parties in multiparty systems and their stability. While stereotypes suggest that a higher number of parties leads to government instability, evidence indicates that many multiparty nations maintain stable governance. Historical examples like Weimar Germany and the 3rd Republic of France illustrate cases of instability correlated with polarized pluralism. This analysis further explores the mechanisms through which countries manage party composition and maintain governmental continuity despite potential fragmentation.

Party systems: What difference does the number and kind of parties make?
Stereotypes Multiparty systems are inherently unstable: • The more parties you have the greater likelihood that either • Cabinets will be short-lived Or • Regimes themselves will be susceptible to collapse (regime instability) instability
Problem: is this valid? Available evidence suggests that is not: • The governments and regimes of most countries with multiparty systems are relatively stable • But some countries have not • Problem: what accounts for the difference?
Polarized pluralism • Moderate v. polarized pluralism (Sartori) • Historically, certain countries with a large number of parties have suffered from chronic cabinet and sometimes regime instability: • Weimar Germany (1918-33) • 3rd Republic France (1875-1940) • Spain, 2nd Republic, 1931-1936 • 4th Republic France (1946-1958) • Italy, 1rst Republic (1945-1993)
Explanations • All had not only a large number of parties, but were sharply polarized as well • Three of these had rather fluid, poorly disciplined parties • Spain, 2nd Republic • France, 3rd and 4th Republics • Only two, Weimar Germany and 2nd Rep Spain suffered regime collapse • Many Italian specialists doubt that Italy, despite frequent cabinet changes, was unstable
Explaining stability • Depends on more than number of parties • Countries with multiparty systems find ways to cope: • Duty of heads of state (presidents or monarchs) to ensure that there is a government • Formal procedures • Use of formateurs and informateurs:
Forming governments • Sweden and Scandinavia – role of parties themselves • Germany • Getting a government in the Netherlands • Role of the monarch • Informateurs • Formateurs • Getting a government in Belgium…
