World War II Although the Igman area may probably have been the scene of military controversy in the earlier History of Bosnia and Herzegovina, the most striking events took place in the course of the 20th century. The area became of substantial military significance during the struggle between Tito's Partisans and the German occupational forces during the Second World War. A renown episode of this struggle took place on Igman during Operation Südost Kroatien associated with what is known as the Second Enemy Offensive in January 1942. The Partisan 1st Proletarian Brigade, pursued by the German 342. Infanterie - Division, crossed Igman in what is known as the "Igman March".

A monument in memory of the Partisan struggle in this area is to be found on Veliko Polje.
