Cause → Event → Consequence
Following the Axis Invasion of Yugoslavia in 1941, the collaborationist Independent State of Croatia was established. Italy, as a dominant Axis partner in the region, sought to formalize its territorial gains and assert political and military supremacy over the new Croatian state, compelling the NDH to enter into binding agreements.
On 18 May 1941, Italy and the NDH concluded the Treaties of Rome, a series of agreements that ceded Dalmatia to Italy, barred Croatian naval activity in the Adriatic, restricted NDH troop movement in Italian-controlled zones, and subordinated Croatian defence, foreign policy, and economy to Italian interests, effectively reducing the NDH to a quasi-protectorate obliged to install a Savoy monarch.
The treaties generated widespread Croatian resentment across political lines and bolstered the Yugoslav Partisan uprising. Italian security arrangements forced reliance on Chetnik auxiliaries, leaving large areas ungarnisoned, which facilitated Partisan recovery after setbacks in Montenegro and eastern Bosnia and enabled establishment of the Bihać Republic in November 1942. Pavelić ultimately repealed the treaties in 1943 after Italy's surrender.
Political Outcome
Italy secured territorial, military, and political dominance over the NDH, which became a quasi-protectorate; treaties were repealed by Pavelić in 1943 after Italy's surrender.
