Political parties evolve continually in response to social movements. As these movements challenge established norms and advocate for specific causes, parties must adapt to maintain electoral viability. For example, the civil rights movement influenced the Democratic Party to embrace more progressive stances on racial equality. Meanwhile, grassroots movements can lead to the formation of new parties or the transformation of existing ones, as seen with shifts towards more populist ideologies. This ongoing relationship illustrates how political parties serve as a reflection of broader social changes, seeking to capture voter sentiment and address emerging issues.
