Nation-building is a process when a government helps to develop a country by creating its own laws, providing services to support people, help build infrastructure, and make sure everyone is getting the same opportunities. It usually involves the government taking a more active role in a country, helping improve things like healthcare, schools, roads and communication systems, as well as helping to protect the environment. It can also involve building relationships with other countries, helping to reduce conflict, protect human rights and create a sense of shared identity. Nation-building is important because it helps people feel like they belong to something bigger than themselves and can lead to a better quality of life.
