Lou Leon Guerrero was elected the first female governor of the U.S. territory of Guam on Tuesday.

Leon Guerrero is the current president of the Bank of Guam.

Guam was established as an unincorporated organized territory of the U.S. in 1950 under the Guam Organic Act. Its governor was federally appointed until 1970, when residents began voting to elect a civilian governor.

Leon Guerrero is the ninth elected governor of Guam. The territory’s top politician is limited to two four-year terms.

Since Guam is not a state, its residents cannot vote for president and its sole member of the House is nonvoting. They do get to vote for party delegates in presidential primaries.
