The US Constitution was influenced by the European enlightenment movement more specifically by the philosopher John Locke. John Locke defended that all people have natural rights - life, liberty and property - and the role of the government is to protect those rights. If the government fails to do so, people have the right to form a new government.
This reflects directly on citizenship and citizens' rights and responsibilities because it gives people more means to get involved in the government and politics, protects voting rights and opens other possibilities such as referendum and city councils.
