The Hague Conventions of 1899 and 1907 preceded the Hague Convention of 1954. The multilateral agreement of 1899 and the slightly amended later version of 1907 contained in Article 27 the commandment for the attacking party to spare historical monuments, educational institutions and institutions of religious, not-for-profit, artistic or scientific significance as far as possible during sieges and bombardments. The party under attack is called upon to mark appropriate buildings. Article 56 also contained a general ban on the confiscation, destruction or damage of such facilities. However, during the First World War, acceptance of these first Hague Conventions was severely restricted by the so-called all-participation clause. It stated that, in the event of war or armed conflict, this Agreement should apply only if all States involved in that conflict are parties to the Convention.
