NASHVILLE (AP) - Republican leaders in the state Legislature are expressing alarm at the number of Tennessee historical events that would be removed from teaching requirements under a proposed overhaul of social studies standards.

In the letter sent Wednesday, the lawmakers argue that it is vital for students to develop and understand how Tennessee has played a key role in national events, including the westward migration, the Civil War, World War II and the civil rights movement. In the words of the authors: "Tennessee history is not trivia."

The letter is signed by Senate Speaker Ron Ramsey of Blountville, Senate Majority Leader Mark Norris of Collierville, Senate Finance Chairman Randy McNally of Oak Ridge, House Deputy Speaker Steve McDaniel of Parker's Crossroads and House Fiance Chairman Charles Sargent of Franklin.
