Movimento Democrático Brasileiro

What Movimento Democrático Brasileiro does

Movimento Democrático Brasileiro (MDB) is a Brazilian political party founded on March 24, 1966 in Brasília, originally created as the permitted opposition party under the military dictatorship's bipartisanship system (AI-2). It is the longest-running political party in Brazil, having played a central role in the democratic transition, the 1988 Citizen Constitution, and multiple governing coalitions that produced three Brazilian presidents (José Sarney, Michel Temer, and shared coalitions with Fernando Henrique Cardoso and Lula). Originally forced to operate as PMDB from 1980 to 2017, the party formally reverted to its historical MDB identity in 2017 to recover its resistance legacy.

MDB operates a national headquarters in Brasília (SHIS QL 12 conjunto 7, Lago Sul) with state directories across all 27 Brazilian states plus the Federal District, and municipal directories nationwide. The party maintains approximately 2 million registered members (filiados) — the largest membership base of any Brazilian party per TSE data — and currently holds 44 federal deputies, 11 senators, 98 state deputies, 3 governors, and 8 vice-governors. The party is organized into six demographic nuclei: MDB Mulher (women), Juventude MDB (youth), MDB Trabalhista (labor), MDB Afro, MDB Socioambiental e Proteção Animal (environment), and MDB Diversidade.

The party's core "products" are political representation and electoral mobilization, with no commercial pricing model. Revenues come from public funding under Brazilian electoral law — the Fundo Partidário (mandatory party fund based on electoral performance) and the Fundo Especial de Financiamento de Campanha (FEFC, electoral-period allocations) — plus voluntary member contributions. Go-to-market is community-led and event-driven: biannual electoral cycles (municipal in even years, general in odd years), national conventions to formalize candidacies and coalitions, and digital channels (mdb.org.br, filie.mdb.org.br, Instagram, Facebook, YouTube, podcast MDB Cast). The Fundação Ulysses Guimarães serves as the party's research and political education foundation, publishing programmatic documents like "Caminhos para o Brasil." Current national president is Deputy Baleia Rossi (elected 2019).
