NGOs emerged in the 20th century to address issues that could not be handled by individual countries alone. They prioritize humanitarian, development, and sustainability causes as alternatives to international organizations perceived as favoring capitalists. NGOs are made up of experts who thoroughly assess situations and potential solutions before launching projects in collaboration with other organizations. They work to directly solve issues and raise awareness through campaigns, now effectively using social media. NGOs carry out relief, development, advocacy, conflict resolution, community services, and state support.
