The Partido dos Trabalhadores (PT), or Workers' Party, is a major political party in Brazil founded in 1980. It emerged from labor movements and leftist groups, advocating for social justice, workers' rights, and economic equality. The party gained prominence in the 2000s, particularly under the leadership of Luiz Inácio Lula da Silva, who served as president from 2003 to 2010. PT's platform focuses on reducing poverty, expanding access to education, and promoting healthcare. The party has faced challenges, including corruption scandals and political opposition, but it remains influential in Brazilian politics, representing a significant segment of the population.
