In the days that followed the outbreak of the
Spanish Civil War, various
left-wing political parties in
Madrid established their own
private police units, which came to be known as
checas, to identify and kill suspected
fascists. Although they sometimes consulted with each other, these
checas were largely independent, responsible only to their own party. They established
kangaroo courts to sentence accused fascists to the
death penalty, which would be carried out by "special brigades" of ex-criminals. They used the euphemism "dar un paseo" () to refer to their
execution. With permission from the Madrid authorities, the socialist established his own "brigade of criminal investigation" in
Castellana and used the archives of the
Ministry of the Interior to track down right-wing party members. Most of those who the
checas killed were rank-and-file party members, while party leaders themselves were imprisoned.
Public order was eventually restored in the Republican zone, with the (CPIP) being dissolved in November 1936.
Santiago Carrillo said his first act as the head of public order on the
Madrid Defence Council was to "get rid of those they later called the checas", which he himself called "parallel police". Some
checa organisers later took positions of authority within the official Republican police force. ==References==
