The term "grassroots movement" signifies a community-driven initiative that seeks to effect change from the bottom-up. These movements often emerge in response to local issues and mobilize ordinary citizens to advocate for social or political reform. Grassroots campaigns rely on volunteerism and community engagement rather than traditional power structures, emphasizing collective action and participation. This approach can empower marginalized voices and drive significant change in policies, fostering a sense of ownership and responsibility among the constituents involved.
