A boycott is a collective decision by individuals or groups to stop using, buying, or dealing with a particular product, service, or organization. This action is often taken to express disapproval or to bring about change, such as in response to unfair practices or policies. Boycotts can be organized for various reasons, including social justice, environmental concerns, or political issues. Historically, boycotts have been used as a powerful tool for activism. For example, the Montgomery Bus Boycott in 1955 was a pivotal event in the Civil Rights Movement, where African Americans refused to use public buses to protest racial segregation. Boycotts aim to create economic pressure on the targeted entity to encourage change.
