Problem: The two groups had different strategies. IMARO as originally conceived sought to prepare a carefully planned uprising in the future, but the Supremacists preferred immediate raids and guerilla operations to foster disorder and a precipitate interventions. On the other hand, a smaller group of conservatives in Salonica organized a Bulgarian Secret Revolutionary Brotherhood . The latter was incorporated in IMARO by 1902 but its members as Ivan Garvanov, were to exert a significant influence on the organization. They were to push for the Ilinden-Preobrazhenie Uprising and later became the core of IMRO right-wing faction. One of the founding leaders of IMARO, Gotse Delchev, was a strong advocate for proceeding slowly, but the Supremacists pressed for a major uprising to take place in the summer of 1903. Delchev himself was killed by the Turks in May 1903. Meanwhile, in late April 1903, a group of young anarchists from the Gemidzhii Circle - graduates from the Bulgarian Men's High School of Thessaloniki launched a campaign of terror bombing, the so-called Thessaloniki bombings of 1903.

There were armed clashes and fatalities in some villages over the following two years. Slovaks from the Polish part of Spis settled mainly in the newly created industrial town of Svit near Poprad, Kezmarok, Poprad, and in depopulated German villages near Kezmarok. Slovaks from the Polish part of Orava settled mainly in Czech Silesia, and in depopulated German villages in the Czech lands . On 10 March 1947 a treaty guaranteeing basic rights for Slovaks in Poland was signed between Czechoslovakia and Poland. As a result, 41 Slovak basic schools and 1 high school were opened in Poland.
