In the same year, the Gentile reform declared Italian as the only language of public education; by 1928, all Slovene and Croatian schools, including private ones, were closed down.
[5][9][10][11] The first organized anti-Fascist resistance activities in the Julian March began in the mid 1920s in the easternmost districts of the region (around Postojna and Ilirska Bistrica), on the border with Yugoslavia.
Local Slovene activists established contacts with the Yugoslav nationalist organization Orjuna, launching first attacks at Italian military and police personnel.
In September 1927, a group of Slovene liberal nationalist activists met on the Nanos Plateau above the Vipava Valley, and decided to form an insurgence organization called TIGR, an abbreviation of the names for Trieste, Istria, Gorizia, and Rijeka.
A few months later, another meeting took place in Trieste, where a group connected to the former established the organization Borba (Fight), which also included some Croat activists from Istria.
In the Gorizia region, the TIGR organization restrained from openly violent actions, and focused mostly on propaganda and on illegal educational, cultural and political activity among larger strata of the population.
The Gorizia section of the TIGR established close connections with the underground Catholic network organized by Christian Socialist activists, centered around the lawyer Janko Kralj and priest Virgil Šček.
On 10 February 1930, in the headquarters of the newspaper Il Popolo di Trieste, the TIGR places a bomb killing the editor Guido Neri.
While in the late 1920s, the organization had close connection with radical Yugoslav nationalist movements, such as ORJUNA, after the reorganization in the 1930s it adopted a more left wing ideology.
The TIGR nevertheless tried to remain above all ideological divisions, maintaining a close relationship with the local Slovene and Croat Roman Catholic lower clergy and grassroots organizations in Istria and the Slovenian Littoral.
The plan was put off at the last minute, most probably because of the pressure by the British intelligence, which opposed such an action in times when Mussolini was conducting an active role in the negotiations that led to the Munich agreement.
After the Anschluss of Austria in 1938, the TIGR expanded its activity to neighboring Nazi Germany, focusing primarily on bomb actions against crucial infrastructure: railways, and high-voltage power lines.
By the time of the Axis invasion of Yugoslavia in April 1941, most of the organization was already dismantled by both Italian and Nazi German secret police and most of its prominent members either sent to concentration camps, killed or exiled.
