The Treaty of Nöteborg between Sweden and Novgorod Republic is signed, regulating the border between the two countries for the first time.
In 1323, Sweden and the Novgorod Republic signed the Treaty of Nöteborg, establishing their first formal border and ending decades of territorial disputes.
On August 12, 1323, envoys from the Kingdom of Sweden and the Novgorod Republic convened at Nöteborg (present-day Shlisselburg) to conclude a historic treaty regulating their mutual boundaries. The accord defined spheres of influence along the Karelian Isthmus and Lake Ladoga, aiming to curtail centuries of skirmishes and raids between the two powers. It represented the first documented delimitation of Swedish–Novgorodian borders and laid the groundwork for future diplomatic relations. By recognizing each party’s territorial claims, the treaty reduced conflict over strategic trading routes in the eastern Baltic region. Though contested in later centuries, the Treaty of Nöteborg held significant legal and symbolic value. It also facilitated more stable trade and cultural exchanges between Scandinavia and northwestern Russia. Historians regard it as a milestone in medieval Northern European diplomacy.

Charles de La Vieuville is arrested and replaced by Cardinal Richelieu as the French king's chief advisor.
In 1624, Cardinal Richelieu supplanted Charles de La Vieuville as chief minister to King Louis XIII, reshaping French politics toward centralized power.
On August 12, 1624, French nobleman Charles de La Vieuville was abruptly arrested at the orders of King Louis XIII, paving the way for the rise of Cardinal Richelieu as the king’s principal advisor. Richelieu, known for his political acumen and vision for state centralization, commenced sweeping reforms to strengthen royal authority and diminish noble and Huguenot power. His ascendancy marked the beginning of a new era in which France would emerge as the preeminent power in Europe. Under Richelieu’s guidance, the French administration expanded its bureaucratic apparatus and pursued aggressive foreign policies to counter Habsburg influence. His strategies laid the foundation for the future absolutism of Louis XIV. The 1624 appointment is recognized as a key turning point in the development of the modern French state. It also cemented Cardinal Richelieu’s reputation as one of the most influential politicians of the 17th century.

Treaty of Allahabad is signed. The Treaty marks the political and constitutional involvement and the beginning of Company rule in India.
On August 12, 1765, the Treaty of Allahabad granted the British East India Company diwani rights in Bengal, marking the start of formal Company rule in India.
On August 12, 1765, Mughal Emperor Shah Alam II granted the diwani rights for Bengal, Bihar, and Orissa to the British East India Company in the Treaty of Allahabad. This agreement followed the Company’s military victory at the Battle of Buxar and solidified its political and fiscal authority in eastern India. By obtaining revenue collection rights, the Company effectively became the de facto ruler of Bengal and laid the administrative foundations for its expanding empire. The treaty also formalized British influence within the declining Mughal polity and reshaped the subcontinent’s power structure. It marked the transition from a trading enterprise to a colonial power with sovereign responsibilities. The financial gains from Bengal’s rich revenue streams fueled further Company military campaigns. Historians often view 1765 as the watershed year when India entered a new era of colonial governance under the East India Company.

The Anjala conspiracy is signed.
A group of Swedish officers sign the Anjala conspiracy to protest King Gustav III's war policies during the Russo-Swedish War. This act marks a bold defiance within the ranks at Anjala.
In a dramatic act of military dissent on August 12, 1788, a group of 113 Swedish officers signed a memorandum at the village of Anjala. They protested King Gustav III's costly and unpopular war against Russia, demanding peace negotiations and legal reforms. This document, known as the Anjala Act or Conspiracy, accused the king of violating the Swedish constitution. The conspirators appealed directly to Empress Catherine the Great for mediation, undermining royal authority. While the conspiracy failed to achieve its aims and officers faced reprimand or exile, it exposed deep divisions within Sweden's military and politics. The episode highlighted tensions between absolutist rule and emerging ideas of constitutionalism in Europe. Today, the Anjala conspiracy remains a symbol of resistance against monarchical overreach.

The Rhône and Loire départments are created when the former département of Rhône-et-Loire is split into two.
Under the French Revolution's administrative reforms, the département of Rhône-et-Loire was divided to create Rhône and Loire, streamlining governance and reflecting new republican ideals.
As part of the sweeping changes following the French Revolution, the government reorganized provincial boundaries to promote equality and efficiency. On August 12, 1793, the single département of Rhône-et-Loire, which had been established earlier, was split into two distinct entities: Rhône, with Lyon as its prefecture, and Loire, centered around Montbrison (later Saint-Étienne). This division responded to population growth, local identities, and the need for more balanced administration. The reforms abolished feudal jurisdictions and replaced them with uniform administrative divisions under central republican control. Each département was governed by an elected council and appointed administrator, reflecting revolutionary principles of citizenship and civic participation. Over two centuries later, Rhône and Loire remain vital economic and cultural regions in eastern France, their origins firmly rooted in this pivotal moment of French history.

French intervention forces William I of the Netherlands to abandon his attempt to suppress the Belgian Revolution.
French troops intervene to halt King William I's campaign against Belgian revolutionaries, securing Belgium's independence bid.
In the aftermath of Belgium's 1830 revolution against Dutch rule, the newly proclaimed Belgian state faced military counterattacks from King William I of the Netherlands. Seeking to reassert control, Dutch forces advanced into Belgian territory in early August 1831. On August 12, French forces, acting under the July Monarchy's guarantee of Belgian neutrality, crossed into Belgium and confronted the Dutch army. The show of force compelled William I to cease his offensive and withdraw, effectively ensuring the survival of the Belgian Revolution. This intervention was formalized by the Treaty of the XXIV Articles later that year, which recognized Belgium's independence and established its borders. The event illustrates the complex interplay of European powers in the post-Napoleonic era and France's role in shaping the continent's political map.

The Hawaiian flag is lowered from ʻIolani Palace in an elaborate annexation ceremony and replaced with the flag of the United States to signify the transfer of sovereignty from the Republic of Hawaii to the United States where it is formally recognized as Hawaii.
In a solemn ceremony at ʻIolani Palace, the Hawaiian flag is lowered and replaced by the U.S. flag, symbolizing Hawaii's annexation by the United States.
Following the overthrow of the Hawaiian Kingdom in 1893 and subsequent political turmoil, the U.S. formally annexed Hawaii on August 12, 1898. A ceremony at ʻIolani Palace in Honolulu marked the transfer of sovereignty, as the American flag replaced the Hawaiian national banner. This act ended centuries of indigenous rule and integrated the islands into the United States as a territory. Proponents touted economic and strategic benefits, while many Native Hawaiians protested the loss of their kingdom. The annexation set the stage for Hawaii's eventual statehood in 1959, but also left a legacy of cultural and legal disputes that continue to resonate. The event remains a pivotal moment in Pacific history and U.S. imperial expansion.

Canada, Mexico and the United States announce completion of negotiations for the North American Free Trade Agreement (NAFTA).
Canada, the United States, and Mexico finalize negotiations on the North American Free Trade Agreement, pioneering a new era of continental trade.
On August 12, 1992, leaders of Canada, Mexico, and the United States announced the completion of negotiations for the North American Free Trade Agreement (NAFTA). The trilateral pact aimed to eliminate trade barriers, reduce tariffs, and foster economic integration across the continent. NAFTA supporters argued that the agreement would boost economic growth, create jobs, and strengthen diplomatic ties among the three nations. Critics, however, voiced concerns about potential job losses in certain industries and environmental impacts. After detailed studies and public hearings, the agreement was signed by President George H. W. Bush, Prime Minister Brian Mulroney, and President Carlos Salinas in December 1992. NAFTA went into effect on January 1, 1994, reshaping manufacturing and agricultural sectors and laying the groundwork for future trade deals. The agreement had a profound impact on supply chains and remains a benchmark for regional trade cooperation.
