As a longstanding and nearly universal concept, diplomatic immunity has long been considered customary law; however, it was traditionally granted on a bilateral, ad hoc basis, leading to varying and sometimes conflicting standards of protection. Modern practices of diplomatic immunity have largely conformed to the 1961 Vienna Convention on Diplomatic Relations, which formally codified the legal and political status of diplomats, and has been ratified by the vast majority of sovereign states.
