(part of the ill-fated invasion of the province of Quebec by les Bostonnais, Americans from the Boston area) during the American Revolutionary War. Trois-Rivières continued to grow in importance throughout this period and beyond. In 1792 it was designated as the seat of a judicial district. In 1852, the Roman Catholic church made this the see of the Diocese of Trois-Rivières. In 1816, Captain A.G. Douglas, a former adjutant at the British military college at Great Marlow, recommended a military college for Catholic and Protestant boys be established at Trois-Rivières. He proposed it operate in a disused government house and he would be superintendent. Douglas' college was intended as a boarding school to educate the young sons of officers, amongst others, in Latin, English language, French Language, History, Geography, Drawing and Mathematics. This preceded the founding of the Royal Military College of Canada in 1876. In 1908, the greater part of the city of Trois-Rivières was destroyed by a fire; most of the city's original buildings, many dating to the French colonial years, were destroyed. Among the surviving buildings were the Ursuline Monastery and the De Tonnancour Manor. As a result of the destruction, a major redesign and renovation of the city was undertaken, including the widening and renewal of many of the city's roads. Many new businesses and industries became established in the town, attracting additional residents. During the mid-century, the city became heavily industrialized and lost jobs during the later restructuring. In the 1960s, Trois-Rivières undertook a large-scale project of economic diversification, including founding several cultural institutions and attractions. The Old City of Trois-Rivières was declared an "historic sector" in 1964. The Laviolette Bridge, linking Trois-Rivières to Bécancour and the south shore of the Saint-Lawrence River, was opened officially on December 20, 1967. In 1969, the city founded the Université du Québec à Trois-Rivières, known for its chiropractic school, its podiatric medical education, and its programs for primary and secondary school education. Although historically an important centre of commerce, trade and population, Trois-Rivières has been superseded by the two major cities of Quebec: the metropolis of Montreal and the capital of Quebec City. It remains as one of the principal medium-sized cities of Quebec, along with Saguenay, Sherbrooke, and Gatineau.
