Marches are organized events where groups of people walk together in a public space to express their views or advocate for a cause. These gatherings can focus on various issues, such as civil rights, environmental protection, or political change. Participants often carry signs, chant slogans, and may listen to speeches to raise awareness and show solidarity. Marches can take place in cities around the world and are often planned in response to specific events or movements. They serve as a way for individuals to unite and demonstrate their collective power, aiming to influence public opinion or government policy.
