[3] Influential American socialist Victor Berger became editor of the Milwaukee Arbeiter Zeitung in 1893 and changed the paper to the daily Wisconsin Worwaerts.

[4] In the early months of 1886, membership in Chicago Internationals (militant unions) swelled to record levels while the Arbeiter-Zeitung and the anarchist publication The Alarm (edited by the Parsons) unleashed a steady stream of editorials railing against capitalism.

[citation needed] As a result of the Haymarket Square bombing of May 4, 1886, police arrested and investigated staff members of the Arbeiter-Zeitung.

Its offices were raided, and speeches and writings published in the paper were part of the evidence used to convict and hang the anarchists who were arrested in its wake.

Its editor, August Spies, and a typesetter, Adolph Fischer, were executed after a widely publicized, six-week trial; business manager Oscar Neebe and chief editorial assistant Michael Schwab were sentenced to death, but later pardoned.

[5] Prosecutors showed that, the night before the bombing, Fischer had proposed that the paper should publish the word ruhe ('peace') — a call for armed men to assemble.
