Final answer:
The Iroquois promoted peace through alliances and treaties, such as the Covenant Chain and the 1684 Treaty of Albany, which established peaceful and beneficial relations with colonial powers.
Step-by-step explanation:
The Iroquois promoted peace primarily through political alliances and treaties with colonial powers, such as the English. Key to these efforts was the Covenant Chain, a series of alliances and treaties with the English, which included annual meetings to discuss land and trade. One significant treaty was the 1684 Treaty of Albany, in which the Iroquois agreed to become subjects of the English monarch, securing peace and mutual benefits between the Iroquois and English colonies. This network of relationships allowed the Iroquois to maintain a level of autonomy, manage their affairs, and keep peace by balancing power between European factions and other Native tribes.
