The Social Democratic Party (SDP) is a political party that advocates for social justice, economic equality, and democratic governance. It typically supports policies that promote welfare programs, workers' rights, and public services, aiming to balance individual freedoms with social responsibility. The party often seeks to address issues like poverty, education, and healthcare through progressive taxation and government intervention. Founded in the late 19th century, the SDP has roots in the labor movement and has evolved over time to adapt to changing political landscapes. It is present in various countries, with notable examples including the Social Democratic Party of Germany and the Social Democratic Party of Finland.
