[2] At the age of six, Maček started attending elementary school in Kupinec,[3] but continued his education in Zagreb, as his father, a public employee, was transferred there.

[8] After returning from hospital in Novi Sad to Zagreb before the Christmas, he was decorated for bravery and promoted to the rank of first lieutenant.

[9] Due to his astigmatism, he was declared unfit to serve on the battlefield, and was appointed a commander of an engineer company, composed of Poles and Ukrainians.

[13] He quickly became a main opponent of King Alexander and was arrested in April 1933 and sentenced to three years in jail for treason.

He nurtured close relations with other opposition parties in Yugoslavia and, although his coalition lost elections in 1938, it remained a force for reckoning.

[15] This triumph proved to be short-lived as Banovina collapsed along with Yugoslavia when it was invaded by the Axis invasion in April 1941.

He called on the supporters of HSS to respect and co-operate with the new regime of Ante Pavelić, while at the same time delegating Juraj Krnjević to represent the Croatian people in the Yugoslav government-in-exile.

In October 1941, he was arrested and interned in Jasenovac concentration camp where he was put under the watch of Ljubo Miloš for some time.

His family shared his internment first in Kupinec, then two months of 1943 (9 January to 9 March) in Luburić's Zagreb apartment (which they shared with Luburić's aged mother and his two sisters), and finally from 9 December 1943 until the collapse of Pavelić's Ustaša regime in May 1945 in his Prilaz 9 house in Zagreb.
