had been sustained by the granting of loans through the Dawes Plan (1924) and the Young Plan (1929). When American banks withdrew their line of credit to German companies, the onset of severe unemployment could not be abated by conventional economic measures. Unemployment thereafter grew dramatically, at 4 million in 1930, and in September 1930 a political earthquake shook the republic to its foundations. The National Socialist German Workers' Party (NSDAP), until then a minor far-right party, increased its votes to 19%, becoming Germany's second largest party, while the Communist Party of Germany (KPD) also increased its votes; this made the unstable coalition system by which every chancellor had governed increasingly unworkable. The last years of the Weimar Republic were marred by even more systemic political instability than previous years, as political violence increased. Four Chancellors (Heinrich Brüning, Franz von Papen, Kurt von Schleicher) and, from 30 January to 23 March 1933, Hitler governed through presidential decree rather than through parliamentary consultation. This effectively rendered parliament as a means of enforcing constitutional checks and balances powerless. Brüning's policy of deflation (1930–1932) On 29 March 1930, after months of lobbying by General Kurt von Schleicher on behalf of the military, the finance expert Heinrich Brüning was appointed as Müller's successor by Reichspräsident Paul von Hindenburg. The new government was expected to lead a political shift towards conservatism. As Brüning had no majority support in the Reichstag, he became, through the use of the emergency powers granted to the Reichspräsident (Article 48) by the constitution, the first Weimar chancellor to operate independently of parliament. This made him dependent on the Reichspräsident, Hindenburg. After a bill to reform the Reich's finances was opposed by the Reichstag, it was made an emergency decree by Hindenburg. On 18 July, as a result of opposition from the SPD, KPD, DNVP and the small contingent of NSDAP members, the Reichstag again rejected the bill by a slim margin. Immediately afterward, Brüning submitted the president's decree that the Reichstag be dissolved. The consequent general election on 14 September resulted in an enormous political shift within the Reichstag: 18.3% of the vote went to the NSDAP, five times the percentage won in 1928. As a result, it was no longer possible to form a pro-republican majority, not even with a grand coalition that excluded the KPD, DNVP and NSDAP. This encouraged an escalation in the number of public demonstrations
