Tribal laws of the two largest Native American tribes in the United States prohibit gay marriage, as do the laws of nine other smaller tribes.
The Navajo and Cherokee Nations, the first and second largest tribes respectively, together have about 600,000 members. The nine smaller tribes that ban gay marriage have another 350,000 members. These tribes all either define marriage as between a man and a woman or explicitly prohibit same-sex marriage, according to the Associated Press (AP).
Since 2011, six of the eleven tribes revisited and upheld their preexisting legal definitions of marriage as between a man and a woman, AP researchers found.
Due to their status as sovereign nations, these 11 tribes will not need to change their marriage laws, which govern nearly one million tribal members, even if the Supreme Court legalizes gay marriage later this month.
