3:30 p.m.–COLUMBIA, S.C. (AP) — The latest on rallies, marches and speeches honoring the Rev. Martin Luther King Jr. (all times local):

Thousands of Texans took to the streets Monday for marches, speeches and volunteer efforts to remember slain civil rights leader Martin Luther King Jr. on the federal holiday in his name.

Organizers planned for more than 200,000 people for the annual MLK march in San Antonio, billed as one of the largest in the country with adults and children walking the nearly 3 mile route together. Participants carried signs, U.S. and Texas flags and linked arms in a show of support for communities working together.

San Antonio police did not immediately return a message Monday on number of participants in the march organized by the city’s MLK Jr. Commission.

The history of the San Antonio MLK march goes back to mourning after King’s 1968 assassination. The Rev. R.A. Callies Sr., a San Antonio pastor and teacher, began leading small processions honoring King’s legacy shortly after the slaying, according to the MLK Jr. Commission website.

Those processions grew over the years, with the theme of Monday’s march being “Uniting Communities to Advance Humanity.”
