This triggered a nationalist reaction and the coup d'état of 9 June 1923 eventually resulted in Stamboliykski's assassination. An extreme right-wing government under Aleksandar Tsankov took power, backed by the army and VMRO, which waged a White terror against Agrarians and Communists. In 1926, after the brief War of the Stray Dog, the Tsar persuaded Tsankov to resign, a more moderate government under Andrey Lyapchev took office and an amnesty was proclaimed, although the Communists remained banned. A popular alliance, including the re-organised Agrarians, won the elections of 1931 under the name "Popular Bloc".
