Persia attempted to ratify the Treaty of Constantinople , by demanding that the Ja'fari, also known as the Imamiyyah was to be accepted as a fifth legal sect of Islam. In 1743, Nader Shah declared war on the Ottoman Empire. He demanded the surrender of Baghdad. The Persians had captured Baghdad in 1623 and Mosul in 1624, but the Ottomans had recaptured Mosul in 1625 and Bagdad in 1638. The Treaty of Zuhab in 1639 between the Ottoman Empire and the Safavid Empire had resulted in peace for 85 years. After the fall of the Safavid Dynasty, Russia and the Ottoman Empire agreed to divide the northwest and the Caspian region of Persia, but with the advent of Nader Shah, the Russians and the Turks withdrew from the region. Nader Shah waged war against the Ottomans from 1730 to 1736 but it ended with a stalemate. Nader Shah afterwards turned east and declared war on the Moghul Empire and invaded India, in order to refund his wars against the Ottomans.

In April 1920 Poland launched the large-scale Kiev Offensive in hopes to capture Ukraine. Initially successful, the Polish Army started retreating after Russian counterattacks in early June 1920. Soon the Soviet forces began to threaten Poland's independence as they reached and crossed the Polish borders. On July 9, Polish Prime Minister Wadysaw Grabski asked the Allied Powers in the Spa Conference for military assistance in the war with the Soviets. The conference proposed that the Polish forces would withdraw behind the Curzon Line, the Soviet forces would stop 50km to the east of the line, the Lithuanian forces would take control of Vilnius, and all other disputes would be settled via negotiations in London. Grabski opposed the transfer of Vilnius, but under pressure of British Prime Minister Lloyd George, agreed to the resolution on July 10. At the same time Soviets and Lithuanians negotiated the Soviet-Lithuanian Peace Treaty, which was signed on July 12, 1920. Russia recognized Lithuanian independence and withdrew any territorial claims. The treaty drew the eastern border of Lithuania, which the Lithuanians continued to claim as their de jure state border until World War II. Vilnius Region, including Brasau, Hrodna, Lida, and Vilnius, was recognized to Lithuania. On August 6, after long and heated negotiations, Lithuania and Soviet Russia signed a convention regarding withdrawal of Russian troops from the recognized Lithuanian territory. However, the troops began to retreat only after the Red Army suffered a heavy defeat in Poland.
