The US state of Louisiana has elected its first non-white governor, Bobby Jindal, since the 1870s.
Mr Jindal has promised to fight corruption in Louisiana
Mr Jindal, 36, also becomes the youngest US governor and the first Indian-American to head a state.
The Republican took 54% of the vote to win outright over his nearest rival, Democrat Walter Boasso, who got 18%.
Outgoing Democratic Governor Kathleen Blanco chose not to run again after she was widely criticised for her handling of the 2005 Hurricane Katrina crisis.
The Oxford-educated son of Indian immigrants, Mr Jindal narrowly lost the 2003 election to Ms Blanco.
In his victory speech, Mr Jindal repeated his election pledge to fight corruption in the state.
"They can either go quietly or they can go loudly, but either way they will go," he said, referring to people who were "feeding at the public trough".
He has also promised to cut taxes and improve education.
