Macedonian terrorism was virtually ended by the putsch of 1934. The government, the People's Bloc, which was a coalition of four parties including the Bulgarian Agrarian Union was overthrown by the so-called Zveno--or link--group. The Zveno group was headed by Kimon Georgiev and was aided by the League of Reserve Officers. As soon as it seized power, Zveno suspended the constitution and dissolved parliament. The king was left with only nominal powers. Although the group did succeed for the most part in ridding the country of Macedonian terrorism, its rule was overtly authoritarian. By 1935 the king, with the aid of the military, had regained his power and replaced the Zveno group with a more moderate government.
With the reestablishment of the monarchy, a royal dictatorship took power and ruled over Bulgaria until 1943, when Boris died. There were at this time no forces left to oppose the king, political parties were negligible, and only a shadow parliament existed. Ironically, the military, which had aided the Zveno in the overthrow of the king, now was an instrument of his control.
Foreign relations under Boris III before World War II were leading the country again inevitably into a war that would bring it to total defeat. In 1934, despite the suppression of IMRO by the newly formed government, Romania, Yugoslavia, Greece, and Turkey, as in the Second Balkan War, were once again wary of Bulgaria's irredentist ambitions. In that year the four powers signed the Balkan Pact, from which Bulgaria naturally was excluded, in order to prevent Bulgarian encroachment in the area. Although Bulgaria and Yugoslavia later established a rapprochement in 1937, the potential of a Bulgarian annexation of Macedonia was still considered a threat by its neighbors.
During the 1930s, while Bulgaria was viewed with suspicion by its neighbors, it began to form new friendships with Germany and Italy. Boris had married the daughter of King Victor Emanuel of Italy, a country that had already become fascist, thus strengthening ties with that country. At the same time, Bulgaria began to solidify its ties with Germany, principally by means of trade. A new-founded prosperity was based almost exclusively on German trade, an arrangement that eventually weakened the country. Within a short period German agents were pouring into the country. Thus, Bulgaria was on one side alienated from its neighbors and on the other being drawn into the nazi-fascist camp.
