The war portal


War is a state of armed conflict between states, governments, societies and informal paramilitary groups, such as mercenaries, insurgents and militias. It is generally characterized by extreme violence, aggression, destruction, and mortality, using regular or irregular military forces. Warfare refers to the common activities and characteristics of types of war, or of wars in general. Total war is warfare that is not restricted to purely legitimate military targets, and can result in massive civilian or other non-combatant suffering and casualties.

The scholarly study of war is sometimes called polemology (/ˌpɒləˈmɒləi/ POL-ə-MOL-ə-jee), from the Greek polemos, meaning "war", and -logy, meaning "the study of".

While some scholars see war as a universal and ancestral aspect of human nature, others argue it is a result of specific socio-cultural or ecological circumstances.

A Canadian WWI recruiting poster

The military history of Canada entails millennia of armed actions in the territory encompassing modern Canada, and the role of the Canadian military in conflicts and peacekeeping worldwide. For at least 10,000 years, the area that would become Canada was the site of intertribal wars among First Nation groups. Beginning in the 16th century, the arrival of Europeans led to conflicts with the Natives and among the colonizing Europeans in the New World. Starting in the 17th century, the region was the site of fighting between the French and the British for more than a century. New challenges soon arose when the northern colonies chose not to join the American Revolution and remained loyal to the British crown. Americans looked to extend their republic and launched an invasion in 1812. After Canada's independence, and amid much controversy, a fully-fledged Canadian military was created. Canada's links to Britain remained strong, and Canadian forces joined their British counterparts in the Boer War, the First and Second World Wars. Since the Second World War, Canada has been committed to multilateralism and has gone to war only within large multinational coalitions such as in the Korean War, the Gulf War, and the 2001 invasion of Afghanistan.
