When was Christianity introduced to the Iroquois Indians?

Christianity was introduced to the Iroquois Indians in the early 17th century, primarily through the efforts of French Jesuit missionaries. These missionaries began arriving in the region around the 1620s, aiming to convert the Indigenous population to Christianity. The interaction led to the establishment of missions among the Iroquois, which continued into the 18th century, despite varying degrees of acceptance and resistance from the tribes.
