Led by a large Macedonian group in Sofia, the strong nationalist elements remaining in Bulgaria found the new pacifist policy alarming. The urban working class, unaided by agrarian reforms, gravitated to the communists or the socialist workers. Inflation and industrial exploitation continued. Many of Stamboliiski's subordinates inflamed social tensions by taking very dogmatic positions in favor of peasant rights. The Bulgarian right, silent since the war, reorganized into a confederation called the National Alliance. Stamboliiski's Orange Guard jailed the leaders of that group in 1922, temporarily stopping its momentum. Meanwhile, in late 1922 and early 1923, Macedonian nationalists occupied Kiustendil along the Yugoslav border and attacked government figures to protest rapprochement with Yugoslavia and Greece. Stamboliiski responded with mass arrests, an accelerated campaign against IMRO terrorism, a purge of his own fragmented and notoriously corrupt party, and a new parliamentary election. These dictatorial measures united the agrarians' various opponents (IMRO, the National Alliance, army factions, and the social democrats) into a coalition led by Aleksandur Tsankov. The communists remained outside the group. Bulgaria's Western creditors would not protect a government that had rejected their reparations policy. In June 1923, Stamboliiski was brutally assassinated by IMRO agents, and the conspirators shortly took control of the entire country with only scattered and ineffectual agrarian resistance.
