Portuguese forces under the command of Pedro Lopes de Sousa begin an unsuccessful invasion of the Kingdom of Kandy during the Campaign of Danture in Sri Lanka.
In 1594, Portuguese troops led by Pedro Lopes de Sousa embarked on the Campaign of Danture but failed to conquer the independent Kingdom of Kandy in Sri Lanka.
Determined to expand their control in Sri Lanka, the Portuguese launched an expedition against Kandy under Pedro Lopes de Sousa. The invaders faced fierce resistance in the mountainous terrain and underestimated local guerilla tactics. Cut off from supplies and ambushed by Kandyan forces, the Portuguese suffered heavy casualties. The failure at Danture preserved Kandy’s sovereignty and thwarted European domination of the island’s interior. This defeat humbled Portugal’s ambitions and shaped the island’s colonial struggle for decades.

John Guy sets sail from Bristol with 39 other colonists for Newfoundland.
In 1610, English entrepreneur John Guy departed Bristol with 39 colonists to establish one of the first permanent English settlements in Newfoundland.
Sponsored by the Bristol Society of Merchant Venturers, John Guy’s voyage marked England’s early push into North America. The group aimed to develop fisheries and trade along Newfoundland’s coast, founding what became the colony at Cupids. They faced harsh winters, limited supplies, and challenges in relations with the indigenous Beothuk people. Despite difficulties, the settlement endured for several years and served as a foothold for future English colonization. Guy’s expedition laid the groundwork for England’s Atlantic presence and the expansion of the Newfoundland Company.

Isaac Newton publishes Philosophiæ Naturalis Principia Mathematica.
In 1687, Isaac Newton published the landmark work 'Philosophiæ Naturalis Principia Mathematica', establishing the laws of motion and universal gravitation.
Newton’s Principia, released by the Royal Society, presented three laws of motion that formed the foundation of classical mechanics. He introduced the universal law of gravitation, explaining celestial and terrestrial bodies with a single mathematical framework. The work employed geometric proofs and advanced the use of calculus. Principia transformed physics and astronomy, influencing Enlightenment thinkers and later scientific developments. Its publication is considered one of the most significant milestones in the history of science.

The Second Continental Congress adopts the Olive Branch Petition.
In 1775, the Second Continental Congress adopted the Olive Branch Petition in a final effort to avoid war with Great Britain during the American Revolution.
Drafted chiefly by John Dickinson, the Olive Branch Petition affirmed colonial loyalty to King George III while requesting redress of grievances. The Congress sought to avert full-scale conflict by appealing directly to the monarch for reconciliation. King George III refused to receive the petition and declared the colonies in open rebellion. Its rejection closed the door on peaceful settlement and paved the way for the Declaration of Independence in 1776. The petition remains a poignant symbol of the colonists’ initial desire for compromise.

The Convention of Artlenburg is signed, leading to the French occupation of the Electorate of Hanover (which had been ruled by the British king).
In 1803, the Convention of Artlenburg was signed, allowing Napoleonic France to occupy the Electorate of Hanover under the personal union with the British crown.
Following the collapse of the Peace of Amiens, French forces under Marshal Bernadotte advanced into Hanover and forced its capitulation at the Convention of Artlenburg. The agreement dismantled Hanoverian defenses and led to a French garrison controlling the territory until 1805. This occupation strained relations between Britain and France and extended the Napoleonic Wars into the German states. Hanover’s strategic location tied to the British monarchy added diplomatic complexity to the conflict. The convention exemplified France’s policy of territorial consolidation on the continent.

The success of these militias challenged assumptions about Spanish imperial weakness and inspired early independence sentiments. The events laid groundwork for the May Revolution and the eventual drive for Argentine independence.
