Thubten Gyatso, the 13th Dalai Lama, returned to Tibet in January 1913 from Sikkim, where he had been residing. When the new ROC government apologised for the actions of the Qing and offered to restore the Dalai Lama to his former position, he replied that he was not interested in Chinese ranks, that Tibet had never been subordinated to China, that Tibet was an independent country, and that he was assuming the spiritual and political leadership of Tibet. Because of this, many have read this reply as a formal declaration of independence. The Chinese side ignored the response, and Tibet had thirty years free of interference from China.
Also in 1913, the Irish Citizen Army was founded by the trade unionists and socialists James Larkin and James Connolly following a series of violent incidents between trade unionists and the Dublin police in the Dublin lock-out.
In the summer of 1913, Mexican conservatives who had supported Huerta sought a constitutionally elected civilian alternative to Huerta, brought together in body called National Unifying Junta. Political parties proliferated in this period, so that by the time of the October congressional elections there were 26.
In 1912, the town of Leipzig, seat of the annual Leipzig Book Fair, the Kingdom of Saxony and the Börsenverein der Deutschen Buchhändler (Association of German booksellers) agreed to found a German National Library in Leipzig. Starting 1 January 1913, all publications in German were systematically collected (including books from Austria and Switzerland).
Huerta's presidency is usually characterized as a dictatorship. From the point of view of revolutionaries at the time and the construction of historical memory of the Revolution, it is without any positive aspects. "Despite recent attempts to portray Victoriano Huerta as a reformer, there is little question that he was a self-serving dictator." There are few biographies of Huerta, but one strongly asserts that Huerta should not be labeled simply as a counter-revolutionary, arguing that his regime consisted of two distinct periods: from the coup in February 1913 up to October 1913, during which time he attempted to legitimize his regime and demonstrate its legality by pursuing reformist policies.
On 3 July 1913, he was voted for membership in the Prussian Academy of Sciences in Berlin. Max Planck and Walther Nernst visited him the next week in Zurich to persuade him to join the academy, additionally offering him the post of director at the Kaiser Wilhelm Institute for Physics, which was soon to be established. He was officially elected to the academy on 24 July.
The most important dispute was over the Shatt al-Arab waterway. Iran repudiated the demarcation line established in the Anglo-Ottoman Convention of Constantinople of November 1913. Iran asked the border to run along the thalweg, the deepest point of the navigable channel.
The Coolidge X-ray tube was invented by William D. Coolidge. It made possible the continuous emissions of X-rays. Modern X-ray tubes are based on this design, often employing the use of rotating targets which allow for significantly higher heat dissipation than static targets, further allowing higher quantity X-ray output for use in high powered applications such as rotational CT scanners.
European swordsmanship always had a sportive component, but the duel was always a possibility until World War I. Modern sport fencing began developing during the 19th century as the French and Italian military academies began codifying instruction. The Olympic games led to standard international rules, with the Féderation Internationale d'Escrime founded in 1913.
Churchill pushed for higher pay and greater recreational facilities for naval staff, an increase in the building of submarines, and a renewed focus on the Royal Naval Air Service, encouraging them to experiment with how aircraft could be used for military purposes. He coined the term "seaplane" and ordered 100 to be constructed. Some Liberals objected to his levels of naval expenditure; in December 1913 he threatened to resign if his proposal for four new battleships in 1914–15 was rejected.
The Great Lakes Storm of 1913, historically referred to as the "Big Blow" the "Freshwater Fury," or the "White Hurricane," was a blizzard with hurricane-force winds that devastated the Great Lakes Basin in the Midwestern United States and Ontario, Canada from November 7 through November 10, 1913. The deadliest and most destructive natural disaster to hit the lakes in recorded history, the Great Lakes Storm killed more than 250 people, destroyed 19 ships, and stranded 19 others.
