May 25, 1521: The Diet of Worms, an assembly called by Holy Roman Emperor Charles V in response to the growing “Protestant” reform movement led by Martin Luther, culminates with the Edict of Worms. In that proclamation, Charles declared Luther “a notorious heretic” and promised that “those who will help in his capture will be rewarded generously for their good work.” A plan to arrest Luther, who had previously testified before the diet and was on his way home to Wittenburg, was thwarted by Frederick III, Elector of Saxony, who “kidnapped” Luther and stashed him in Wartburg Castle for his own safety. He remained there until the following March, writing and translating the New Testament into German while his movement became a schism and Protestantism began to separate from the Catholic Church.
May 25, 1946: The British Mandate of Transjordan gains independence as “The Hashemite Kingdom of Transjordan” with the crowning of Emir Abdullah I as king. May 25 is annually commemorated in Jordan as Independence Day.
May 25, 1981: Leaders from Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates sign the Gulf Cooperation Council charter in Abu Dhabi, formally marking the birth of that organization. The GCC was intended to streamline political and economic relations between the six Gulf Arab states, with the potential for tighter unification down the road. It has led to the creation of a Gulf customs union and a number of joint infrastructure projects, but big plans regarding monetary union and increased regional cohesion have been largely undermined by the Saudi-Qatari rivalry.

May 26, 1908: A British drilling operation discovers a commercially-viable oil deposit at Masjed Soleyman, in Iran’s Khuzestan province. Lucky them! This was the first oil find in the Middle East and obviously began the region’s transformation into the stable, economically advantaged paradise it is today. The strike was made under the terms of the “D’Arcy Concession,” a 1901 agreement between British oil baron William Knox D’Arcy and Iranian ruler Mozaffar al-Din Shah Qajar that gave D’Arcy exclusive rights to explore for oil in Iran in exchange for a payment of 20,000 pounds and a mere 16 percent of any future profits. The Burmah Oil Company, which backed D’Arcy’s operation, formed the Anglo-Persian Oil Company (which goes by BP nowadays) and began extracting Iranian oil under the concession’s extremely lopsided terms. Let’s just say this led to some problems down the road and leave it at that.
May 26, 1918: The short-lived Democratic Republic of Georgia declares independence from the considerably shorter-lived Transcaucasian Democratic Federative Republic, which in turn formed out of the collapse of the Russian Empire. Although Georgia fell to a Red Army invasion in early 1921 and became a Soviet republic, this not-quite-three year period of independence was formative in terms of the development of Georgian nationalism, and after the country regained its independence from the USSR the Georgian government established May 26 as Independence Day.
May 26: 1966: British Guiana, which you likely know better as Guyana, gains its independence. May 26 is Independence Day in Guyana.
May 27, 1644: A Qing army under the Shunzhi Emperor’s regent, Dorgon, along with a Ming Dynasty army under general Wu Sangui, defeats the forces of the Shun Dynasty under Emperor Li Zicheng at the Battle of Shanhai Pass. During the collapse of the Ming Dynasty, the Manchurian Qing began to threaten China’s northern borders, while rebels under Li attacked the Ming from within the empire. Wu commanded one of the gates through the Great Wall, and faced with threats from either side he opted to allow the Qing through the gate to deal with Li. Wu initially seems to have meant for the Qing to help him restore the Ming Dynasty once the rebels were dispatched, but instead Dorgon continued on to Beijing, toppled the Ming, and claimed the Mandate of Heaven for the Shunzhi Emperor.
May 27, 1942: In “Operation Anthropoid,” two Czechoslovakian soldiers successfully assassinate the head of the Reich Main Security Office and the Nazi governor of Bohemia and Moravia, Reinhard Heydrich, in Prague. The soldiers and their fellow conspirators had been trained and advised by operatives from Britain’s Special Operations Executive. They initially believed the attack had failed, but Heydrich later succumbed either to his wounds or to an infection. By some estimates the Nazis killed roughly 5000 people during the investigation/collective punishment campaign that ensued.
May 28, 621: With only around 10,000 soldiers at his disposal, prince Li Shimin of the nascent Tang Dynasty defeats an army of the rival Xia regime that was at least ten times that size at the Battle of Hulao. Considered by some historians to be one of the most important battles ever fought, Hulao was the decisive engagement of the civil wars that followed the collapse of the Sui Dynasty and Li’s victory ensured that the Tang would emerge as the new ruling dynasty of China.
May 28, 1905: A Japanese fleet decisively defeats a Russian fleet at the Battle of Tsushima, sinking 21 Russian vessels and capturing seven more while losing only three of its own. Tsushima is noteworthy in that it was the first naval battle fought between two fleets built around modern battleships using the telegraph for communications. It’s also noteworthy for the overwhelming nature of the Japanese victory, which brought the Russo-Japanese War to an end on Japanese terms, marked the beginnings of Japan’s imperial expansion, and caused a wave of “Yellow Peril” discourse to sweep through the West.
