Hundreds of people have turned out in Mankato to mark the 150th anniversary of the hanging of 38 Dakota men - the largest mass execution in U.S. history.
 
A new "Dakota 38" memorial was dedicated during the nearly two-hour ceremony in Reconciliation Park Wednesday.

Up to 500 people packed the area. About 60 horse riders rode in for the ceremony, and a group of Dakota runners from Fort Snelling also arrived.
 
The hangings on Dec. 26, 1862, marked the end of the U.S.-Dakota War that took place along the Minnesota River valley that fall.
