LITTLE ROCK, Ark. — Arkansas’ governor signed legislation Tuesday ending the state’s practice of commemorating Confederate Gen. Robert E. Lee on the same holiday as slain civil rights leader Martin Luther King Jr., leaving only two states remaining that honor the two men on the same day.

Republican Gov. Asa Hutchinson championed the bill, which also expands what is taught in schools about civil rights and the Civil War, saying it would unify the state and improve its image. His signature comes two years after similar efforts repeatedly failed before a legislative panel, with critics saying it belittles the state’s Confederate heritage.

“I expected this debate would divide us, but instead during the debate we listened to each other and the conversation brought us together,” Hutchinson said before signing the measure into law.

Here are some details about the new law and background about the original dual-holiday:

WHAT DOES THE LAW DO?

The new law will remove Lee from the state holiday that honors King on the third Monday in January. The Civil War general will instead will be honored with a memorial day, not a state holiday, on the second Saturday in October that will be marked with a gubernatorial proclamation.

The law also requires the Arkansas Department of Education to expand what’s taught in classrooms about the Civil War and civil rights, including more of an emphasis on civil rights leaders such as King, as well as more about civilian and military leadership during the Civil War.

WHY DID IT PASS?

Hutchinson early last year announced he would push for an end to the dual holiday and later made it part of his legislative package for this year’s session. He even took the unusual step of testifying directly in front of the Senate and House committees in favor of the legislation.

The provision on civil rights and Civil War history also helped ensure the measure would go before the House and Senate education committees, rather than the House State Agencies and Governmental Affairs Committee where it failed two years ago.

WHAT DOES THIS MEAN FOR OTHER STATES?

Alabama and Mississippi are now the only states that have joint Lee-King state holidays. It’s unclear whether Arkansas’ move will advance efforts to end the dual holidays in those states.

A proposal is pending in the Alabama Legislature to end the state’s joint holiday in January and move the commemoration of Lee’s birthday to Confederate Memorial Day, which Alabama celebrates as a state holiday in April. The measure has yet to clear a legislative committee.

No bills to end the dual holiday were filed in Mississippi this year.
