An anti-Trump rally is planned for Boston Common Saturday afternoon, to be followed by a march through downtown Boston.
The event, organized by a group called Refuse Fascism, will coincide with 20 like-minded rallies across the United States, including ones in New York, Chicago, and Los Angeles.
The aim, said Carl Dix, an organizer of Saturday’s demonstrations, is to create “a political crisis in the country that can force the removal of the Trump/Pence regime.’’
“This nightmare must end,’’ said Dix during a phone interview on Thursday. “The Trump/Pence regime must go — that’s what is pulling people together.’’
Thursday, Dix said he was “not in a position’’ to offer an estimate for the number of people he thought would show up. He said organizers are hoping for several thousand demonstrators in New York and Los Angeles.
In August, a controversial “free speech’’ rally on the Common drew about 50 participants and an estimated 40,000 counterprotesters.
“We’re definitely working to tap into that,’’ he said of August’s large counterdemonstration. “Frankly, we’d love to reach those numbers, but we’re not sure at all if we could do that.’’
According to Dix, state Representative Mike Connolly, a Cambridge Democrat, is among those scheduled to speak on Saturday.
Connolly said he would be advocating for inclusion at the rally, adding that “It’s important to not allow the regime to divide people.’’
“I think I’m going to convey the concerns of Trump as a fascist regime are very real,’’ said Connolly. “We can’t take anything for granted and the Trump-Pence regime is truly a threat to humanity.’’
The rally is scheduled to start at the Parkman Bandstand at 4 p.m. After the rally, the demonstrators will march through downtown Boston, said Dix. The event, from the start of the rally to the end of the march, is expected to last four hours, he said.
Dix said the hope is that the event will trigger a series of demonstrations and create a groundswell of political action similar to that in South Korea earlier this year, when that country’s leader, President Park Geun-hye, was ousted by a court ruling after massive demonstrations.
Other events are planned later this month, he said. On Nov. 9, demonstrators will be traveling to Manchester, N.H., to join a protest of Stephen Bannon, a former Trump adviser who is scheduled to speak there.
On Nov. 10, Somerville Theatre will host a screening of the film “Sir! No Sir!’’ a documentary that chronicles anti-war protests in the US armed services during the Vietnam War, said Dix.
Organizers from Saturday’s rally on the Common also plan on attending a veterans peace march in the area on Nov. 11, said Dix. Another anti-Trump demonstration is planned for Copley Square on Nov. 18, he said.
