up nearly everyone who had had the remotest connection with the July 20 plot. The discovery of letters and diaries in the homes and offices of those arrested revealed the plots of 1938, 1939 and 1943, and this led to further rounds of arrests. Under Himmler's new Sippenhaft (blood guilt) laws, all the relatives of the principal plotters were also arrested. Very few of the plotters tried to escape, or to deny their guilt when arrested. Those who survived interrogation were given perfunctory trials before the People's Court and its judge Roland Freisler. Eventually some 5,000 people were arrested and about 200 were executed—not all of them connected with the July 20 plot, since the Gestapo used the occasion to settle scores with many other people suspected of opposition sympathies. After February 3, 1945, when Freisler was killed in an American air raid, there were no more formal trials, but as late as April, with the war weeks away from its end, Canaris's diary was found, and many more people were implicated. Executions continued down to the last days of the war. Timeline Pre-war resistance: 1933–1939 There was almost no organized resistance to Hitler's regime in the period between his appointment as chancellor on January 30, 1933, and the crisis over Czechoslovakia in early October 1938. By July 1933, all other political parties and the trade unions had been suppressed, the press and radio brought under state control, and most elements of civil society neutralised. The July 1933 Concordat between Germany and the Holy See ended any possibility of systematic resistance by the Catholic Church. The largest Protestant church, the German Evangelical Church, was generally pro-Nazi, although a few church members resisted this position. The breaking of the power of the SA in the "Night of the Long Knives" in July 1934 ended any possibility of a challenge from the "socialist" wing of the Nazi Party, and also brought the army into closer alliance with the regime. Hitler's regime was overwhelmingly popular with the German people during this period. The failures of the Weimar Republic had discredited democracy in the eyes of most Germans. Hitler's apparent success in restoring full employment after the ravages of the Great Depression (achieved mainly through the reintroduction of conscription, a policy advocating that women stay home and raise children, a crash re-armament programme, and the incremental removal of Jews from the workforce as their
