In late July 1471, the influential Shin Buddhist leader Rennyo built the Yoshizaki Gobo temple complex on the coast of Echizen Province. This foundation created a new regional center for the Jodo Shinshu sect, fostering religious outreach and community gatherings. Yoshizaki Gobo became a safe haven for followers fleeing unrest in Kyoto and other regions. The site served not only as a place of worship but also as a hub for sermons, charitable works, and educational activities. Rennyo's leadership at Yoshizaki helped solidify his reputation as a reformer and played a crucial role in the spread of Shin Buddhism throughout Japan.

After a months-long siege, Cortés's forces breached the defenses of Tenochtitlan on August 13, 1521, ending Aztec rule. The fall of the lake city marked a pivotal moment in the Spanish conquest of Mexico, leading to vast territory claims. Disease, internal dissent, and superior weaponry contributed to the Aztecs' defeat. Spain's victory introduced colonial governance, reshaping the region's demographics, culture, and economy. The conquest opened the way for further European expansion into the Americas and significant cultural exchange (and exploitation).

On July 27, 1536, tensions between rival Buddhist sects erupted into open violence. Warrior-monks from Mount Hiei's Enryakuji allied with the Rokkaku samurai to enter Kyoto. They targeted Nichiren temples, setting 21 major sites ablaze across the city. The rebellion underscored the political power of militant temples and the volatility of religious conflicts in Muromachi Japan. The destruction devastated the Nichiren community and prompted government efforts to curb temple armies' autonomy.

Michael Servetus, a Spanish humanist and physician, openly challenged the orthodox doctrine of the Trinity. Both Catholic and Protestant leaders deemed his views heretical, leading to his flight across Europe. On August 13, 1553, Calvin's Geneva authorities captured him during his clandestine visit. Servetus's arrest highlighted the era's religious intolerance even among reformers. He would later be tried and executed, becoming a symbol of early advocacy for religious freedom and intellectual dissent.

In July 1587, the retainers of Higo Province rebelled against enforced land surveys by warlord Sassa Narimasa. Led by Chikayoshi Kumabe, the uprising aimed to protect traditional land rights and local autonomy. The Higo Kokujin Ikki reflected widespread peasant and minor samurai grievances under centralizing rule. Although the revolt was quickly suppressed, it underscored tensions in Japan’s feudal restructuring. The incident revealed the limits of Oda Nobunaga's legacy and the challenges Toyotomi Hideyoshi faced in unifying the country.

Originally established on Shinobazuyama, the Confucian temple (Ninooka Seido) served as Tokugawa learning center. On August 13, 1690, it was relocated to Yushima, becoming the famed Yushima Seido. The move aimed to centralize Confucian education and reinforce Neo-Confucian ideology within the shogunate. Yushima Seido later became Japan’s premier academy for scholars, influencing government policy and civil service. Its grand lecture hall and serene gardens symbolized Edo’s dedication to scholarship and moral governance.

In the War of the Spanish Succession, Allied commanders John Churchill and Prince Eugene struck French-Bavarian forces along the Danube. Their victory at Blenheim halted French expansion and preserved Austria’s position in Europe. The battle involved over 50,000 soldiers in fierce fighting under blistering summer heat. Allied artillery and coordinated assaults broke enemy lines, leading to a rout of the Franco-Bavarian troops. Blenheim became one of the most celebrated British victories of the era, elevating Marlborough to national hero status.

Matsudaira Sadanobu, serving as chief councilor (rōjū), sought to revive fiscal and moral discipline in the Tokugawa shogunate. Emulating the 18th-century Kyōhō Reforms, he issued directives to curtail lavish spending and reinforce Confucian ethics. He targeted corrupt officials, streamlined administration, and supported agricultural and financial stability. The Kansei Reforms would shape shogunal policy for over a decade, impacting education, commerce, and social order. They reflected Enlightenment-era ideas filtered through Japanese tradition, aiming at long-term restoration of shogunate authority.

The Hōkō-ji Daibutsu, once Japan's tallest bronze Buddha, stood as a symbol of religious devotion in Kyoto. Late on August 12, 1798, a powerful lightning bolt struck the statue's head, igniting internal wooden supports. By the next morning, worshippers discovered the collapsed figure, reduced to charred fragments amidst temple grounds. The destruction marked a profound loss for the Buddhist community and architectural heritage. Reconstruction efforts would span decades, but few could match the original statue's scale and majesty.

In the aftermath of the Napoleonic Wars, Britain and the Netherlands negotiated colonial boundaries. Signed on August 13, 1814, the London Treaty formalized control over the Malay Peninsula and western Sumatra. It aimed to stabilize trade routes and reduce conflicts between the two maritime powers. The agreement laid groundwork for the Dutch East Indies and the Straits Settlements under British oversight. This treaty influenced Southeast Asia’s colonial map, impacting local societies, economies, and future decolonization.

江戸時代後期、幕府は蘭学研究者への弾圧を強め、蛮社の獄で高野長英が伝馬町牢屋敷に収監されていた。弘化元年6月30日（1844年8月13日）、牢屋敷の火災に乗じて看守をかいくぐり脱獄した。高野はその後も各地を転々としながら反幕府的活動を継続し、蘭学と思想の自由を訴え続けた。この脱獄劇は幕末の言論統制の象徴とされ、後の維新運動に影響を与えた。

南米チリは環太平洋火山帯に位置し地震多発地域です。1868年8月13日、北部アリカ沖でM8.9の巨大地震が発生し、大規模な地滑りや津波を引き起こしました。沿岸部の住民に甚大な被害が及び、港湾施設や家屋が壊滅的な打撃を受けました。日本など太平洋各地でも津波観測が記録され、国際的にも注目された災害となりました。
