Fundamental rights are essential human rights that must be offered to all citizens regardless of attributes. They include rights such as freedom of speech, religion, privacy, marriage, education, justice, and fair trials. Scholars have different classifications of fundamental and human rights, including some that see certain rights as absolute that should never be violated. International agreements like the UN Charter and Universal Declaration of Human Rights also outline fundamental rights and freedoms. However, states may restrict some rights in exceptional circumstances like for national security or the common good, though others argue rights should never be overridden.
