Fort Oswego was an 18th-century trading post in the Great Lakes region in North America, which became the site of a battle between French and British forces in 1756 during the French and Indian War. The fort was established in 1727, on the orders of New York governor William Burnet, adjacent to a 1722 blockhouse that had originally been a way station for French traders. The log palisade fort established a British presence on the Great Lakes. In 1756, the fort's garrison of British soldiers from the 50th and 51st regiments were easily defeated by a combined French and Native American force. More than one hundred British soldiers were killed, many of them after the fort had been formally surrendered. The French took a further 1,500 British prisoners, and destroyed the fort itself. The site is now included in the city of Oswego, New York.

The Battle of Fort Oswego was one in a series of early French victories in the North American theatre of the Seven Years' War won in spite of New France's military vulnerability. During the week of August 10, 1756, a force of regulars and Canadian militia under General Montcalm captured and occupied the British fortifications at Fort Oswego, located at the site of present-day Oswego, New York. In addition to 1,700 prisoners, Montcalm's force seized the fort's 121 cannons. The fall of Fort Oswego effectively interrupted the British presence on Lake Ontario and removed it as a threat to the nearby French-controlled Fort Frontenac. The battle was notable for demonstrating that traditional European siege tactics were viable in North America when applied properly in the right circumstances and terrain.

The Port of Oswego is the main waterfront area of the City of Oswego in Oswego County, New York. Over the course of its history, the Port of Oswego has been the focus of military conflict and conquest, asite of record trade revenue, and a significant part in the History of American expansion and industrialism. Today the Port of Oswego is a shadow of its once-powerful self but still proves to be useful as trade continues in the central New York region. Early explorers in the 17th century of Dutch, French, and English origin realized the value of an all-water route connecting the French settlements along the St. Lawrence River with the Dutch settlement of New Amsterdam. This would create a trade route that would stretch well over 500 miles (800 km) and give the controller of this route a significant advantage for turning profits in the New World. The Port of Oswego would become the focal point of this perceived route and bring the country that owns it almost infinite resources for constructing an empire in the New World. The history of activity at the Port can be divided into four great periods of development: The Fur Trading Era, The Salt Era, The Lumber and Grain Era, and The Coal Era.
