Invocationes dei have a long tradition in European
legal history outside national constitutions. In
ancient times and the
Middle Ages, gods or God were normally invoked in contracts to guarantee the agreements made, Treaties between Christian nations customarily began with an invocation of God until the late 19th century. When written constitutions became the norm for modern states in the 19th century, several European states carried this tradition over to their founding documents and then retained it, while others – notably
laicist France and states influenced by it – did not do so, so as to preserve the state's religious neutrality. Some European countries whose constitutions do
not make reference to God include Norway (1814), Luxembourg (1868/1972), Iceland (1944/68), Italy (1947), Portugal (1976) and Spain (1978).
Maine,
Massachusetts,
Michigan,
Minnesota,
New Jersey,
New Mexico,
Nevada,
Pennsylvania,
Texas,
Wisconsin, and
Washington, and the U.S. territory
Puerto Rico, make a reference to God. They generally use an
invocatio of "God the Almighty" or the "Supreme Ruler of the Universe". When the newly independent nations of Eastern Europe and Asia adopted new democratic constitutions in the early 1990s following the
fall of the Soviet Union and the end of the
Eastern Bloc, they took a variety of approaches to the issue of mentioning God: • The great majority of the new constitutions, including those of all ex-
Soviet republics and dependent states except Hungary, Poland and Ukraine, make no mention of the supernatural in the preamble (Belarus, Bosnia and Herzegovina, Bulgaria, Estonia, Lithuania, Russia, Slovenia, Serbia and Montenegro), including those rooted in a Muslim background (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan), or have no preamble at all (Romania, Latvia, Albania, Armenia and Azerbaijan). Instead, they make reference to secular values such as "liberty, justice and law” (Estonia) or "the generally accepted principles in the modern world" (Croatia). • The preambles to the
Constitution of the Czech Republic and of
Slovakia do not mention God directly, but refer to the country's "spiritual wealth" (Czech Republic) or to "the spiritual heritage of
Cyril and Methodius" (Slovakia). • Poland's and Ukraine's constitutional preambles contain a
nominatio dei (see the list below). Most recently, the inclusion of a
nominatio dei was hotly debated in the preparation of the preamble to the proposed
European Constitution. The governments of the member states eventually failed to reach consensus for a reference to
Christianity. (See:
