LIVERPOOL, New York — Members of the Six Nations of the Iroquois and experts in Native American legal and civil rights issues are hosting a conference in central New York for discussions on 500-year-old Vatican edicts whose impacts are still felt today.

The conference being held Saturday and Sunday at the Great Law of Peace Center outside Syracuse focuses on how Native American tribes were impacted by what’s known as the Doctrine of Discovery.

The term refers to papal bulls issued by the Catholic Church in the 15th century as Europeans were setting out to explore the New World. The edicts gave explorers the right to claim lands for their Christian monarchs.

The Iroquois Confederacy has called on the Vatican to renounce the Doctrine of Discovery for having a negative impact on indigenous people.
