Party Analysis: Five Star Movement (Italy)
Anti-Politics, Italian-style
Once dismissed as a digital protest vehicle, the Five Star Movement (Movimento 5 Stelle, M5S) has become one of the most consequential political actors of Italy’s post-crisis era. Founded in 2009 by comedian Beppe Grillo and digital entrepreneur Gianroberto Casaleggio, M5S emerged as a rejection of Italy’s established party system, combining populist rhetoric with a distinctive emphasis on direct democracy, environmentalism, and anti-corruption reform.
Its electoral fortunes have fluctuated sharply. After peaking as the largest party in the 2018 general election, M5S secured 15.4 per cent of the vote in September 2022, winning 52 seats in the Chamber of Deputies and 28 in the Senate - enough to remain a central opposition force, though no longer dominant. By late 2025, polling placed the party at around 12 - 13 per cent, reflecting both consolidation after years of internal turmoil and the constraints of a strategic shift toward the left under former prime minister Giuseppe Conte.
M5S’s trajectory tells a broader story about Italian democracy: the rise of anti-politics, its partial institutionalisation, and the difficulty of sustaining insurgent movements once protest gives way to governance.
Why the Five Star Movement Exists
M5S emerged from a deep crisis of representation. The late-2000s financial crash exposed long-standing weaknesses in Italy’s political economy - low growth, youth unemployment, regional inequality, and pervasive corruption - while reinforcing public perceptions that mainstream parties were insulated from accountability.
Grillo and Casaleggio channelled this frustration through a novel organisational model. What began as a blog evolved into a movement structured around online mobilisation, local meet-ups, and a rejection of traditional party hierarchies. The “five stars” - public water, sustainable transport, development, digital connectivity, and environmental protection - served less as a coherent programme than as symbolic markers of civic renewal.
Crucially, M5S positioned itself outside the left - right divide, portraying both camps as complicit in a closed political cartel. This stance proved electorally potent in a post-Berlusconi environment marked by cynicism toward elites and scepticism of European economic governance. Support was especially strong among younger voters, urban professionals, and economically marginalised communities in southern Italy, where austerity and public service retrenchment hit hardest.
In this sense, M5S reflected a broader European pattern: populism driven not only by crisis, but by the perception that conventional parties no longer offered meaningful choice.
What the Party Has Achieved
Electorally, M5S’s rise was rapid and disruptive. In 2013 it entered parliament with over a quarter of the vote, becoming the largest single party in the Chamber of Deputies. The 2018 election marked its high point: 32.7 per cent of the vote and 227 deputies, enabling it to lead a coalition government with the right-wing Lega.
In office, M5S translated protest into policy with mixed success. Signature achievements included the introduction of the Citizens’ Income welfare scheme and a package of anti-corruption measures, most notably the Spazzacorrotti decree. Subsequent coalition shifts - from Lega to the centre-left Democratic Party, and later support for Mario Draghi’s technocratic government - reflected both tactical adaptability and ideological ambiguity.
After electoral losses in 2022, the party underwent a process of consolidation under Conte, formalising a clearer centre-left identity and distancing itself from Grillo. This repositioning was reinforced in 2024, when M5S joined the Left group in the European Parliament. Regionally, it has retained influence in parts of southern Italy, most notably with its victory in the 2025 Campania regional election.
While no longer the dominant force it once was, M5S has reshaped Italian politics by normalising debates on welfare provision, political integrity, and environmental transition.
What Success Would Look Like
For M5S, success is now defined less by disruption than by durability. In the short term, this means stabilising its vote share and embedding itself within a broader centre-left electoral bloc capable of challenging the governing right. Achieving this would require consistent polling above the mid-teens and improved coordination with allies in single-member constituencies.
Medium-term ambitions focus on institutional reform: expanding participatory mechanisms, entrenching social welfare protections, and accelerating Italy’s green transition. Conte has increasingly framed these goals within a pro-European, reformist narrative, seeking to reconcile redistribution with fiscal credibility.
In the longer term, M5S aspires to become a permanent pillar of the Italian left - either complementing or supplanting the Democratic Party - while preserving its identity as a movement rooted in civic participation rather than party patronage. Whether digital democracy can be reconciled with stable party organisation remains an open question.
Electoral Rules and Strategic Constraints
Italy’s mixed electoral system has both enabled and constrained M5S. Proportional representation has allowed the party to convert dispersed national support into parliamentary seats, protecting it from sudden collapse as its vote share declined. The 3 per cent threshold has further insulated it from fragmentation on the left.
At the same time, the single-member plurality component has penalised M5S when it has failed to coordinate with allies. Its earlier refusal to form coalitions proved costly, particularly in marginal constituencies where vote-splitting handed victories to the right. Recent regional successes underscore the importance of strategic alliances, but they also highlight the party’s reduced autonomy.
In a system prone to hung parliaments, M5S retains leverage - but only insofar as it can contribute to viable governing majorities. Electoral volatility, low turnout, and competition from both left and right continue to limit its room for manoeuvre.
How Critics See It
Critics on the right portray M5S as fiscally irresponsible and ideologically incoherent, arguing that policies such as Citizens’ Income exacerbate dependency and strain public finances. Its shifting coalition partners are cited as evidence of opportunism rather than principle.
From the centre-left, critics focus on governance capacity and internal democracy. They point to inconsistent policy positions, opaque online decision-making, and administrative failures in municipalities previously run by M5S, most notably Rome. More broadly, sceptics argue that the movement’s populist origins have undermined trust in institutions without offering a sustainable alternative.
Even sympathetic observers question whether M5S’s leftward turn represents ideological maturation or electoral necessity.
How It May Be Remembered
The long-term significance of the Five Star Movement remains uncertain. If it succeeds in institutionalising participatory reforms, sustaining welfare expansion, and contributing to Italy’s ecological transition, it may be remembered as a transformative force that modernised democratic engagement in the digital age.
If, however, it continues to fragment or fades into the broader centre-left, M5S is more likely to be remembered as a symptom of the 2010s crisis era - a powerful but transient revolt against austerity, corruption, and elite detachment.
Either way, its rise marked a decisive break with Italy’s post-war party system. The age of anti-politics may have peaked, but the conditions that produced it - and the questions it raised about representation, accountability, and participation - remain unresolved.
