During this period European powers fought to acquire cultural and economic control of North America, just as they were doing in Europe. At the same time, indigenous peoples competed for dominance in the European fur trade and hunting areas. The European colonial powers sought to hire Native American tribes as auxiliary forces in their North American armies, otherwise composed mostly of colonial militia in the early conflicts. In many cases indigenous warriors formed the great majority of fighting forces, which deepened some of their rivalries. To secure the help of the tribes, the Europeans offered goods and signed treaties. The treaties usually promised that the European power would honor the tribe's traditional lands and independence. In addition, the indigenous peoples formed alliances for their own reasons, wanting to keep allies in the fur and gun trades, positioning European allies against their traditional enemies among other tribes, etc. Many Native American tribes took part in King William's War (1689–1697), Queen Anne's War (1702–1713) (War of the Spanish Succession), Dummer's War (c. 1721–1725), and the French and Indian War (1754–1763) (Seven Years' War).
