On June 14, thousands of protesters peacefully gathered in the streets of downtown San Antonio to express their grievances against President Donald Trump and his administration’s increasingly strict crackdown on immigration.

The event, dubbed the “No Kings” protest, drew in widespread attention after Gov. Greg Abbott said he deployed more than 5,000 members of the Texas National Guard and more than 2,000 Texas DPS troopers to Texas cities where protests were planned, including in San Antonio.

Here’s what to expect for San Antonio’s next “No Kings” protest, slated to take place from 4 p.m. to 6 p.m. on Oct. 18 at Travis Park, despite Trump’s objections.

There are several organizers behind San Antonio’s upcoming “No Kings” protest. According to a news release, 50501 SATX is working “in coordination and support with the Bexar County Democratic Party, San Antonio Alliance Local 67,” as well as the Indivisible Project and the Party for Socialism and Liberation.

50501 SATX is a grassroots organization dedicated to “building a diverse alliance for democracy to defend our freedoms from oligarchy and fascism,” according to its site. San Antonio Alliance Local 67 is a public school employees union, representing teachers and support staff at the San Antonio ISD.

The Indivisible Project was founded in response to Trump’s election, and is dedicated to “taking regular, iterative, and increasingly complex actions to resist the GOPs agenda, elect local champions, and fight for progressive policies,” its site says.

The Bexar County Democratic Party and the Party for Socialism and Liberation are two different organizations aligned with two distinct political parties. Although both political parties have their own unique goals, they are both united in working against Trump’s “authoritarian power grabs.”

On the San Antonio event’s information page, “No Kings” organizers highlighted the importance of peaceful protest.

“A core principle behind all No Kings events is a commitment to nonviolent action,” its site says. “We expect all participants to seek to de-escalate any potential confrontation with those who disagree with our values and to act lawfully at these events.”

Organizers also noted that “Weapons of any kind, including those legally permitted, should not be brought to events.”
