Treaty of Philadelphia
Negotiated by Secretary of State Robert Lansing and British Ambassador Sir Cecil Spring-Rice, the US-UK treaty included the following terms:
*British recognition of the Republic of Ireland and Republic of Quebec
*US possession of Canada and Newfoundland
*US possession of the Sandwich Islands, Bermuda, and the Bahamas
*Self-government for Jamaica and British Honduras
*The sale of the British Virgin Islands to neutral Denmark
*A relatively minor indemnity for US losses, which Britain managed to pay off before the Collapse
Treaty of Arlington
Negotiated personally by Presidents Roosevelt and Semmes at the Lee estate in Virginia (the same site where the US had officially recognized Southern independence in 1863), it provided for:
*Confederate recognition of the US states of Kentucky and Houston
*US possession of Sequoyah
*Portions of Virginia, Arkansas, and Sonora ceded to the US
*A large indemnity, which proved a back-breaking weight on the Confederate economy until 1923
*Confederate ground forces (Army, Marines, and militia) limited to 50,000 officers and men
*Confederate Navy limited to 100,000 tons
*Prohibition upon barrels, machine-guns, artillery, submersibles, and poison gas
Treaty of Potsdam
The meetings and ceremony took place at the palace of Wilhelm II outside Berlin between the German emperor, Karl I of Austria-Hungary, Arthur Henderson of Britain (David Lloyd George's government was annihilated in the 1917 general election) and Georges Clemenceau of France (Aristide Briand having fallen as well). No representatives of Russia were sent due to the ongoing civil war, while junior allies were excluded from the major negotiations:
*Recognition of the Kingdom of Poland and Kingdom of Ukraine, under Hohenzollern and Habsburg monarchs respectively
*Recognition of the Republic of Ireland
*Annexation of Luxembourg to Germany
*Annexation of the remaining portion of Alsace-Lorraine to Germany
*German occupation of Belgium, with a German-appointed governor serving Leopold III, who remained on the throne
*German possession of the Belgian Congo
*Serbia divided between Austria-Hungary and Bulgaria
*Portions of Romania ceded to Bulgaria
*Military restrictions on France similar to those on the Confederacy
*Large reparations from Britain and France to Germany (Germany, Britain, and France provided substantial, generous loans to Austria-Hungary, due to no possibility of money from Russia)
Britain faced no military restrictions and retained the majority of its empire.
Many smaller agreements also came about. Japan, as the only undefeated member of the Entente, signed separate treaties with the US and Germany. The Japanese paid no reparations, but compensated Germany for the loss of its Pacific possessions. During the 1920s they would purchase Indochina from France, and the Dutch East Indies.
The Ottoman Empire, with substantial numbers of German "advisors," defeated the Arab rebellion following the British withdrawal in 1914 and regained the Caucasus territories which had been lost to Russia. The Ottomans received nominal reparations from the UK, regained suzerainty over Egypt, which had been lost to Britain over a century before, and took control of the Suez Canal. A campaign of persecution against the Armenians began in the late 1910s. The US and Germany both formally protested, but without stronger German measures, nothing could be done to stop it. (The Austrians pointedly made no comment.) By the time the campaign ended, over a million Armenians had been killed, a taste of what was to come in Russia, Mexico, Spain, and the Confederacy.
The war in South America continued until 1918. Brazil signed an armistice with Argentina in late 1917, ending her short participation, and the war between the Argentines and Paraguay and Chile ground on until a successful mediation effort by the government of Spain. No significant concessions were made by either side.
Germany created a customs union with the Netherlands and Poland in 1919, while the Austrians did the same with Albania, Romania, and Ukraine in 1921.
When Mikhail II was crowned Tsar of Russia in 1927, he made no effort to pursue his country's claims to Poland and the Ukraine, due to an earlier agreement in which Germany would ship arms to his forces and provide diplomatic support against Japan's designs in Siberia. Germany would come to regret this support, as Mikhail forgot his gratitude and formally demanded the return of both countries in 1941.
