The history of Canada begins with the arrival of Paleo-Indians thousands of years ago. Canada has been inhabited for millennia by Aboriginal peoples, who evolved trade, spiritual and social hierarchies systems. Some of these civilisations had long faded by the time of the first permanent European arrivals (c. late 15th - early 16th centuries), and have been discovered through archaeological investigations. Various laws, treaties, and legislation have been enacted between European settlers and the Indigenous populations.
The history of the petroleum industry in Canada arose in parallel with that of the United States. Because of Canada's unique geography, geology, resources and patterns of settlement, however, it developed in different ways. The evolution of the petroleum sector has been a key factor in the history of Canada, and helps illustrate how the country became quite distinct from her neighbour to the south.
The Oka Crisis was a land dispute between the Mohawk nation and the town of Oka, Quebec, Canada which began on July 11, 1990. It lasted until September 26, 1990. One person died as a result. The dispute was the first of a number of well-publicized conflicts between First Nations and the Canadian government in the late 20th century which were associated with violence.
The crisis developed from a local dispute between the town of Oka and the Mohawk community of Kanesatake. The town of Oka was developing plans to expand a golf course and residential development onto the land which had traditionally been used by the Mohawk. It included pineland and a burial ground, marked by standing tombstones of their ancestors. The Mohawk nation had filed a land claim for the sacred grove and burial ground near Kanesatake, but their claim had been rejected in 1986.
The Oka Crisis was extensively documented and inspired numerous books and films. Canadian filmmaker Alanis Obomsawin has made documentaries about the Oka Crisis, including Kanehsatake: 270 Years of Resistance (1993) and Rocks at Whiskey Trench (2000). These and two additional documentaries on the crisis were all produced by the National Film Board of Canada: Christine Welsh directed Keepers of the Fire (1994), which documented the role of Mohawk women during the crisis, and Alex MacLeod created Acts of Defiance (1993).
