On 4 January 1919, Ebert sacked Emil Eichhorn, the
police chief in Berlin, who was popular with the workers.
On the next day, thousands of workers took to the
streets in protest. The Spartacists saw this as their
chance to undermine the government. They called for an
uprising and a general strike in Berlin and, on 6 January,
over 100,000 workers took to the streets. They seized
the government’s newspaper and telegraph offices. The
Weimar government was losing control of the capital.
