Politics of Brazil

Lore & Background

model, established a federalist democratic republic but denied women and illiterates the vote. The current 1988 constitution was drafted during redemocratization and is expansive, guaranteeing individual rights and including detailed provisions on Social Security and taxes.

Reader's Guide

Brazil's political system is characterized by coalition presidentialism, where the high number of political parties forces the executive to assemble diverse and often ideologically incoherent coalitions to pass legislation. This system, combined with frequent party switching by congressmen, weakens electoral coalitions. The political landscape is divided between internationalist liberals, who favor economic internationalization, and statist nationalists, who support interventionism and state enterprises. As of May 2017, over 16.6 million Brazilians were affiliated with a political party, with the largest being MDB, PT, and PSDB. In 2020, Brazil had more than 30 active parties, with only one defining itself as right-wing, reflecting a political imbalance.

Defining the Discipline

Comparative politics stands as a branch of political science dedicated to the systematic examination of political systems around the globe. Rather than focusing on a single nation, scholars in this field investigate how different countries organize their governance, conduct elections, produce policy, and manage public administration. The discipline is comparative because it seeks to explain why political systems share certain traits or diverge from one another, and it is systematic because it looks for recurring patterns and regularities across cases. Its substantive reach spans democratization, globalization, regional integration, and the interplay between states and societies. Over the past four decades, the field has absorbed a wide range of theoretical lenses—political culture, dependency theory, developmentalism, corporatism, comparative political economy, and new institutionalism—each offering distinct tools for understanding how and why political arrangements evolve. In some contexts, particularly in the United States, the term is loosely used to mean the politics of foreign countries, a usage that many within the discipline dispute.

Two Intellectual Lineages

Philippe C. Schmitter identified two foundational traditions that shape the intellectual genealogy of comparative politics. The first, which he labels sociological constitutionalism, traces back to Aristotle and encompasses thinkers who examined political life through the lens of social forces and historical development. This lineage includes figures such as Machiavelli, Montesquieu, Tocqueville, Marx, Weber, Durkheim, and Pareto. In the twentieth century, it evolved into what was called historical political sociology, carrying forward through scholars like Stein Rokkan, Lipset, Linz, and Eckstein. The second tradition, legal constitutionalism, descends from Plato and centers on the formal structures of law and constitutional design. Its classic contributors include Léon Duguit, James Bryce, A. Lawrence Lowell, and Woodrow Wilson, while twentieth-century continuations include Sartori, Duverger, and Friedrich. Together, these two streams—one emphasizing the social roots of political order, the other the architecture of legal institutions—provide complementary frameworks for understanding how governance systems take shape and function across diverse societies.

Methodological Evolution and Constraints

A defining methodological constraint of comparative politics is that comparisons must be conducted at a fixed point in time, typically the present. Researchers cannot validly juxtapose systems across different historical periods; the objects of comparison must remain static. This requirement has shaped how scholars design their studies and interpret their findings. Historically, the discipline relied heavily on between-country comparisons to address broad questions in political science. However, contemporary research has shifted substantially toward subnational comparisons, examining variation within countries rather than only between them. This subnational turn contributes important methodological, theoretical, and substantive insights to the broader study of politics. The field's name itself reflects its historical association with the comparative method, though scholars like Arend Lijphart emphasize that the discipline's defining feature is methodological rather than substantive—it addresses the how of analysis without prescribing the what. Meanwhile, Peter Mair and Richard Rose argue for a dual definition combining a substantive focus on national political systems with a method of identifying and explaining similarities and differences through shared conceptual frameworks.

Bridging Domestic and Global Politics

Comparative politics plays a vital role in understanding the nature and functions of political systems worldwide, and its insights extend well beyond academic inquiry into the realm of international relations and conflict resolution. Political structures differ markedly across nations due to historical, social, ethical, and racial factors, meaning that even seemingly similar institutions operate in distinct ways. For example, both India and the United States are majority-rule democracies, yet the U.S. employs a liberal presidential system with a president as head of government, while India operates under a parliamentary system led by a prime minister. Decision-making processes also diverge significantly between the two. Although comparative politics and international relations are distinct subfields of political science, they intersect meaningfully: comparative politics investigates the domestic causes of international strategy and examines how global frameworks and approaches influence domestic political conduct. By clarifying global legislative issues and current power dynamics, the discipline equips scholars and policymakers with the analytical tools needed to navigate an increasingly interconnected political landscape.
