Answer:
Humans belong to the type of citizenship called "national citizenship". National citizenship is obtained through the legal process of being born in a country or through naturalization. It grants individuals certain rights and privileges such as the right to vote, the right to work and live in the country, the right to receive protection and assistance from the government, and the right to hold a passport and travel to other countries. Some countries also have dual citizenship, allowing individuals to hold citizenship in more than one country, but it varies depending on each country's laws and regulations.
Additionally, some countries are signatories to international treaties such as the United Nations Convention on the Reduction of Statelessness, which allows for the grant of citizenship to individuals who would otherwise be stateless (such as those born in a country that does not recognize them as citizens), or to people who have been displaced and have lost their citizenship.
In summary, national citizenship grants an individual legal rights and protection within a country and it is acquired through different ways depending on the laws of each country.
