The American Jewish Historical Society is facing a backlash over its decision to cancel two events, after a campaign by right-wing activists who had criticized them as anti-Israel.

The society, which is based at the Center for Jewish History in Manhattan, announced on Tuesday that it was canceling a reading of “Rubble Rubble,” a play by Dan Fishback, and a panel about the 1917 Balfour Declaration, which was co-sponsored by the group Jewish Voice for Peace. Mr. Fishback is also a member of the group, which is part of the broader movement calling for boycott, divestment and sanctions against Israel, known as BDS.

The two events, planned months ago, came under criticism from right-wing activists in recent days, as the latest salvo in a wider campaign against the new executive director of the Center for Jewish History, David Myers, over his involvement in groups like New Israel Fund, which promotes human rights and social justice.

And on Monday night, the board of the historical society voted to cancel them.

“While the programs themselves may have merit, they do not align with the mission of the A.J.H.S.,” the board said in a statement posted online.
