The Treaty of Batum was signed in Batum on June 4, 1918, between the Ottoman Empire and the three Transcaucasian states: the First Republic of Armenia, the Azerbaijan Democratic Republic and the Democratic Republic of Georgia. It was the first treaty of the First Republic of Armenia and the Azerbaijan Democratic Republic and had 14 articles.

The Berlin Conference of 1884–1885, also known as the Congo Conference or West Africa Conference, regulated European colonization and trade in Africa during the New Imperialism period and coincided with Germany's sudden emergence as an imperial power. The conference was organized by Otto von Bismarck, the first chancellor of Germany. Its outcome, the General Act of the Berlin Conference, can be seen as the formalisation of the Scramble for Africa, but some scholars of history warn against an overemphasis of its role in the colonial partitioning of Africa and draw attention to bilateral agreements concluded before and after the conference. The conference contributed to ushering in a period of heightened colonial activity by European powers, which eliminated or overrode most existing forms of African autonomy and self-governance.

The Treaty of Berlin was signed on 13 July 1878. In the aftermath of the Russian victory against the Ottoman Empire in the Russo-Turkish War of 1877–1878, the major powers restructured the map of the Balkan region. They reversed some of the extreme gains claimed by Russia in the preliminary Treaty of San Stefano, but the Ottomans lost their major holdings in Europe. It was one of three major peace agreements in the period after the 1815 Congress of Vienna. It was the final act of the Congress of Berlin and included Great Britain and Ireland, Austria-Hungary, France, Germany, Italy, Russia and the Ottoman Empire. Germany's Otto von Bismarck was the chairman and dominant personality.

The Treaty of Brest-Litovsk was a separate peace treaty signed on March 3, 1918, between the new Bolshevik government of Russia and the Central Powers, that ended Russia's participation in World War I. The treaty was signed at German-controlled Brest-Litovsk, after two months of negotiations. The treaty was agreed upon by the Russians to stop the further invasion. According to the treaty, Soviet Russia defaulted on all of Imperial Russia's commitments to the Allies and eleven nations became independent in Eastern Europe and western Asia.

The Treaty of Bucharest was concluded on 10 August 1913, by the delegates of Bulgaria, Romania, Serbia, Montenegro and Greece. The Treaty was concluded in the aftermath of the Second Balkan War and amended the previous Treaty of London, which ended the First Balkan War. About one month later, the Bulgarians signed a separate border treaty with the Ottomans, who had regained some territory west of the Enos-Midia Line during the second war.

The Treaty of Constantinople was the product of the London Conference of 1832 which opened in February 1832 with the participation of the Great Powers on the one hand and the Ottoman Empire on the other. The factors which shaped the treaty included the refusal of Leopold of Saxe-Coburg-Gotha to assume the Greek throne. He was not at all satisfied with the Aspropotamos–Spercheios line, which replaced the more favorable Arta–Volos line considered by the Great Powers earlier.

The first League of Armed Neutrality was an alliance of European naval powers between 1780 and 1783 which was intended to protect neutral shipping against the Royal Navy's wartime policy of unlimited search of neutral shipping for French contraband. British naval commanders followed their instructions with care, ordered away boarding parties and made seizures with impunity. Four fifths of ships sailing, according to one estimate, made port in safety, but it was the loss of the other fifth that rankled. By September 1778, at least 59 ships were taken prize-8 Danish, 16 Swedish and 35 Dutch, not mentioning others from Prussia. Protests were enormous by every side involved.

The First Geneva Convention for the Amelioration of the Condition of the Wounded in Armies in the Field, held on 22 August 1864, is the first of four treaties of the Geneva Conventions. It defines "the basis on which rest the rules of international law for the protection of the victims of armed conflicts." After the first treaty was adopted in 1864, it was significantly revised and replaced in 1906, 1929, and finally 1949. It is inextricably linked to the International Committee of the Red Cross, which is both the instigator for the inception and enforcer of the articles in these conventions.

The Hague Conventions of 1899 and 1907 are a series of international treaties and declarations negotiated at two international peace conferences at The Hague in the Netherlands. Along with the Geneva Conventions, the Hague Conventions were among the first formal statements of the laws of war and war crimes in the body of secular international law. A third conference was planned for 1914 and later rescheduled for 1915, but it did not take place due to the start of World War I.

The Treaty of Karlowitz was signed on 26 January 1699 in Sremski Karlovci, concluding the Great Turkish War of 1683–1697 in which the Ottoman Empire had been defeated at the Battle of Zenta by the Holy League. It marks the end of Ottoman control in much of Central Europe, with their first major territorial losses after centuries of expansion, and established the Habsburg Monarchy as the dominant power in the region.

In the London Straits Convention concluded on 13 July 1841 between the Great Powers of Europe at the time—Russia, the United Kingdom, France, Austria and Prussia—the "ancient rule" of the Ottoman Empire was re-established by closing the Turkish Straits, which link the Black Sea to the Mediterranean, from all warships whatsoever, barring those of the Sultan's allies during wartime. It thus benefited British naval power at the expense of Russia as the latter lacked direct access for its navy to the Mediterranean.

The Metre Convention, also known as the Treaty of the Metre, is an international treaty that was signed in Paris on 20 May 1875 by representatives of 17 nations. The treaty created the International Bureau of Weights and Measures (BIPM), an intergovernmental organization under the authority of the General Conference on Weights and Measures (CGPM) and the supervision of the International Committee for Weights and Measures (CIPM), that coordinates international metrology and the development of the metric system.

The Treaty of Paris of 1856 brought an end to the Crimean War between the Russian Empire and an alliance of the Ottoman Empire, Great Britain, the Second French Empire and the Kingdom of Sardinia.

The Agreement of St.-Jean-de-Maurienne was an agreement between France, Italy and Great Britain, which emanated from a conference in a railway car at Saint-Jean-de-Maurienne on April 19, 1917, and signed by the allies between August 18 – September 26, 1917.
