As between the parties to the 1907 Convention, this Convention has replaced the 1899 Convention (see Article 4 of the 1907 Convention). These States or their successor States remain formally bound by the 1899 Convention in their relations with the other parties thereto. Seventeen of the States which ratified the 1899 Convention did not ratify the 1907 version (Argentina, Bulgaria, Chile, Colombia, Ecuador, Greece, Italy, Korea, Montenegro, Paraguay, Persia, Peru, Serbia, Spain, Turkey, Uruguay, Venezuela). The two versions of the Convention and the Regulations differ only slightly from each other.

The Convention and the Regulations were revised at the Second International Peace Conference in 1907. The Conference of 1899 succeeded in adopting a Convention on land warfare to which Regulations are annexed. One of the purposes for which the First Hague Peace Conference of 1899 was convened was 'the revision of the declaration concerning the laws and customs of war elaborated in 1874 by the Conference of Brussels, and not yet ratified' (Russian circular note of 30 December 1898).
