AUSTIN — Texas has removed more Confederate symbols than any other state over the last three years, according to a new report from the Southern Poverty Law Center.

Since the deaths of nine people in a 2015 shooting at a historic black church in Charleston ignited a movement to take down Confederate monuments, the report said, 110 nationwide — 31 in Texas — have been removed or changed. That includes flags and the names of schools, parks, buildings and roads.

Symbols removed in Texas include a statue of Robert E. Lee that stood in Dallas' Lee Park until September and statues of four Confederate figures at the University of Texas that were taken down in August. In December, the Dallas ISD board voted to change the names of three elementary schools that honored Confederate generals.

Other states that have removed a significant number of Confederate symbols since 2015 include Virginia (14), Florida (9), Georgia (8), Maryland (6), North Carolina (6) and Oklahoma (5).

“We’ve seen a remarkable effort to remove Confederate monuments from the public square, yet the impact has been limited by a strong backlash among many with Southerners who still cling to the myth of the ‘Lost Cause’ and the revisionist history that these monuments represent,” Heidi Beirich, director of the SPLC Intelligence Project, said in the report.

Despite the removals, the center said 1,728 Confederate symbols remain — 772 monuments, 100 public schools named after Lee, 80 counties and cities named after Confederate figures and nine paid holidays for state employees in five states. Fort Hood in Texas is also one of 10 U.S. military bases named after Confederate fighters.

The report said Texas still has 68 Confederate monuments, some of which are up for debate. The Dallas City Council is considering removing a Confederate War Memorial downtown. In Austin, Rep. Eric Johnson, D-Dallas, has asked the governor to remove a Confederate plaque outside his office in the Capitol.

Gov. Greg Abbott's office said it is still studying the issue, but El Paso Rep. Joe Moody filed a request asking for an official opinion from the attorney general. The attorney general's office has asked 13 people — including Abbott and Lt. Gov. Dan Patrick — to submit information by Tuesday "if they have a special interest or expertise in the subject matter."

Texas also observes Confederate Heroes’ Day on Jan. 19 and designates April as Confederate History Month.
