The earliest known inhabitants of the island were the First Nations native people, who lived in the area as early as 4,000 years ago, growing maize and building fortified villages. Evidence also shows the Saint Lawrence Iroquoians established the village Hochelaga in the area 200 years before the arrival of the French. French explorer Jacques Cartier visited this village in 1535 and estimated a population of more than one thousand.
70 years later, another French explorer reported the St Lawrence Iroquoians and settlements had disappeared, likely due to an epidemic of disease from the Europeans outmigration or wars between tribes.
A fur trading post was established in the area in 1611 at the site of present-day Pointe-a-Calliere. A Roman Catholic mission was established to evangelize the natives in 1642. The region became a base for fur trading and French exploration. To create a large French settlement, the Mohawks were encouraged to move from the fur trading post, creating Kahnewake(a mission village), Kanesatake (north of the Ottawa River) and Akwesasne (further upriver). All three are now Mohawk reserves.
The new Canadian territory was ruled as a French colony until it was surrendered to Great Britain in 1760. Montreal was eventually incorporated in 1832, becoming the largest municipality in British North America in less than thirty years. It was the capital of the Province of Canada from 1844 until 1849. By 1951, Montreal was home to more than one million people, and it was during this decade that the city hosted the World’s Fair, constructed the tallest skyscrapers in the country and created the subway system (Montreal Metro).
The city was merged with 27 nearby municipalities on the Island of Montreal in 2002 to create a unified city. Many mergers were rescinded later as the move was unpopular in several suburbs. 13% of the population of the island in many municipalities voted to leave the unified city in 2004, leaving 15 total municipalities on the Island of Montreal.
