Progressive Parties are political groups that advocate for social reform and change, often focusing on issues like economic equality, environmental protection, and civil rights. They aim to address the needs of marginalized communities and promote policies that support social justice and sustainability. These parties often emerge in response to perceived injustices or failures of the existing political system. Examples include the Progressive Party in the United States during the early 20th century and various Green Parties around the world, which emphasize ecological issues alongside social progress.
