Former state representative Carlos Henriquez, the first person ousted from the House by his colleagues in nearly a century, told the Globe on Thursday he will decide in the next two to three weeks whether he will run for his old seat.

Henriquez, a Democrat from Dorchester, set Beacon Hill abuzz Wednesday when he posted a picture of himself on Facebook with the words “State Representative Fifth District’’ and “Committed to Community.’’ On Twitter, he urged people to join “a campaign for the people,’’ with a link to a volunteer form that listed several possible duties, including door-knocking and fundraising.

Henriquez, ousted from the House in 2014 after he was convicted of assaulting his girlfriend, said Thursday that he was still talking to supporters and deciding whether to run for office or launch a broader “civic engagement’’ campaign.

“If I can play a more vital role being the push from the outside, I will seriously consider that,’’ he said, in a telephone interview.

Henriquez, 39, said voters need to be educated about House leadership’s tight grip on power. “Putting a monarch in charge of the democratic process in the House concerns me,’’ he said.

The former state representative, who maintains his innocence in the assault case, also said he can add a missing voice — a man’s voice — to the discussion around domestic violence.

He said he attended a court-mandated, 40-week batterers course connected with his conviction and learned a lot about how women are perceived in American culture.

Henriquez’s former House colleagues had a mostly negative reaction to his potential candidacy on Wednesday, with several rallying around state Representative Evandro C. Carvalho, who won a special election to replace Henriquez after he was expelled from the chamber.
