Extradition is the official process whereby one country transfers a suspected or convicted criminal to another country. Between countries, extradition is normally regulated by treaties. Where extradition is compelled by laws, such as among sub-national jurisdictions, the concept may be known more generally as rendition. It is an ancient mechanism, dating back to at least the 13th century BC, when an Egyptian Pharaoh, Ramesses II, negotiated an extradition treaty with a Hittite King, Hattusili III.
