Final answer:
Canada adopted the principles of democracy and citizenship from Ancient Greece. Democracy in Athens allowed citizens to participate directly in governance, while citizenship provided rights and responsibilities within the state. These principles have shaped Western political thought and are central to Canadian governance.
Step-by-step explanation:
The two important principles that Canada adopted from Ancient Greece are democracy and citizenship. Ancient Greece, particularly the city-state of Athens, is credited with the development of democracy, which is basically 'rule by the people.' This system of government allowed for direct participation by citizens in political decision-making, which included both rich and poor adult males. Citizenship entailed certain rights and responsibilities within the polis, or city-state, including participation in government and the legal system. Ancient Greek political philosophies and these concepts have had a profound impact on Western political thought, including Canadian governance.
Moreover, Greek philosophers such as Aristotle connected the concept of democracy with ethical living and the development of virtue within a community. He postulated that good governance and the rule of law were vital for citizens to live a virtuous and fulfilled life, which necessitated a well-structured political society. Canada's adoption of democratic governance and the importance of citizenship reflects these ancient Greek ideals, intertwining individual rights and community responsibilities with the operation of its political system.
