Final answer:
The main causes of conflicts between Europeans and Native Americans were differing views on land ownership, the European drive for territorial expansion and wealth, and the competition among European powers. Alliances and the arms race made the situation more volatile.
Step-by-step explanation:
Conflicts that arose between Europeans and Native Americans (NAs) were primarily driven by differing conceptions of land ownership, the desire for wealth and territory, the need for autonomy and liberty, and differing economic, political, and religious systems. While native peoples viewed the land and its resources as communal, Europeans held a proprietary view of land which led to the establishment of colonies with defined boundaries. This infringement upon the natives' way of life inevitably led to conflict.
European imperialism was another key catalyst for conflicts. As European powers grew stronger, they sought to expand their influence and control to other parts of the world, causing clashes not only with native populations but also among the European nations themselves.
The build-up of military alliances and the arms race also set a stage for conflict. The imperial and territorial ambitions of various European powers meant that even minor disputes could trigger a broader conflict, as demonstrated by the complex web of alliances described in the lead up to World War I.
