Solidarity refers to a sense of unity, mutual support, and shared interests or goals among individuals or groups. It involves standing together, showing empathy, and providing assistance to others, often in times of need or struggle.

Solidarity can manifest in various ways, such as:

1. Social movements: People coming together to advocate for a common cause, like human rights or environmental issues.
2. Community support: Neighbors helping neighbors, or community members rallying around a family in need.
3. Labor unions: Workers uniting to negotiate better working conditions or wages.
4. International cooperation: Countries working together to address global challenges.

Solidarity fosters a sense of belonging, promotes collective action, and can lead to positive change.
