On 10 May 1926 a coalition government of Christian Democrats and Agrarians was formed, and that same day Józef Piłsudski, in an interview with Kurier Poranny, said that he was "ready to fight the evil" of sejmocracy and promised a "sanation" of political life. The newspaper edition was confiscated by the authorities. The night of 11 May to 12 May a state of alert was declared in the Warsaw military garrison, and some units marched to Rembertów, where they pledged their support to Piłsudski. On 12 May they marched on Warsaw and captured bridges over the Wisła River. Meanwhile, Wincenty Witos' government declared a state of emergency. , Warsaw, 12 May 1926, during the May Coup d' État. At right is Gen. Gustaw Orlicz-Dreszer. At about 17:00 hours, Marshal Piłsudski met President Stanisław Wojciechowski on the Poniatowski Bridge. Piłsudski demanded the resignation of Witos' cabinet, while the President demanded Piłsudski's capitulation. With no result in this round of negotiations, fighting erupted about 19:00 hours. Next day a new round of negotiations was begun, mediated by ArchbishopAleksander Kakowski and Marshal of the SejmMaciej Rataj. These negotiations, however, brought no change to the stalemate. On 14 May the Polish Socialist Party declared its support for the rebels and called for a general strike, supported by the Railwaymen's Union. The strike by socialist railwaymen paralyzed communications and prevented pro-government military reinforcements from reaching Warsaw. Eventually, to prevent the Warsaw fighting from turning into a country-wide civil war, Wojciechowski and Witos resigned their offices. During these events, 215 soldiers and 164 civilians were killed, and some 900 people were wounded. A new government was formed under Prime Minister Kazimierz Bartel, with Piłsudski as minister of military affairs. On 31 May the National Assembly nominated Piłsudski to be president, but he declined. Eventually Ignacy Mościcki became the new president; Piłsudski, however, wielded much greater de facto power than his military ministry nominally gave him.
Consequences
Piłsudski initiated a Sanation government, directed at restoring moral "health" to public life. Although until his death in 1935 Piłsudski played a preponderant role in Poland's government, his formal offices – apart from two stints as prime minister, in 1926–28 and 1930 – were for the most part limited to those of minister of defense and inspector-general of the armed forces. The adoption of a new Polish constitution in April 1935, tailored by Piłsudski's supporters to his specifications — providing for a strong presidency — came too late for Piłsudski to seek that office. But the April Constitution would serve Poland until the outbreak of World War II and would carry its Government in Exile through the war and beyond.
