On the cold, snowy night of March 5, 1770, a mob of American colonists gathers at the Customs House in Boston and begins taunting the British soldiers guarding the building in protest of unpopular taxation.
The protesters pelted British troops with snowballs until Private Hugh Montgomery was hit, causing him to discharge his rifle into the crowd. The other soldiers began firing as well, until five colonists lay dead or dying.
Crispus Attucks, Patrick Carr, Samuel Gray, Samuel Maverick, and James Caldwell died from their wounds, and their deaths are regarded by some historians as the first casualties of the American Revolutionary War.
On March 9, 1916, Germany declared war on Portugal, who earlier that year honored its alliance with Great Britain by seizing German ships anchored in Lisbon's harbor.
When World War I began in 1914, Portugal was a fledgling democratic republic, and newly elected president Manuel JosÉ de Arriaga was anxious about the security of Portugal's colonial holdings in Angola and Mozambique but desperate to remain neutral in the war.
In order to secure international support for its authority in Africa, Portugal begrudgingly entered the war on the side of Britain and the Allies. Its participation was at first limited to naval support, but by February of 1917, Portugal had 50,000 men stationed on the Western Front.
The Seven Years' War, a global conflict known in America as the French and Indian War, ends with the signing of the Treaty of Paris by France, Great Britain, and Spain.
In the early 1750s, France's expansion into the Ohio River valley repeatedly brought the country into armed conflict with the British colonies. In 1756, the British formally declared war against France.
In the first year of the war, the British suffered a series of defeats at the hands of the French and their broad network of Native American alliances. However, in 1757, British Prime Minister William Pitt (the older) recognized the potential of imperial expansion that would come out of victory against the French and borrowed heavily to fund an expanded war effort. Pitt financed Prussia's struggle against France and her allies in Europe and reimbursed the colonies for the raising of armies in North America. By 1760, the French had been expelled from Canada, and by 1763 all of France's allies in Europe had either made a separate peace with Prussia or had been defeated. In addition, Spanish attempts to aid France in the Americas had failed, and France also suffered defeats against British forces in India.
The Seven Years' War ended with the signing of the treaties of Hubertusburg and Paris in February 1763. In the Treaty of Paris, France lost all claims to Canada and gave Louisiana to Spain, while Britain received Spanish Florida, Upper Canada, and various French holdings overseas. The treaty ensured the colonial and maritime supremacy of Britain and strengthened the 13 American colonies by removing their European rivals to the north and the south. Fifteen years later, French bitterness over the loss of most of their colonial empire contributed to their intervention in the American Revolution on the side of the Patriots.
