[3] His family may have been Albanian Muhaxhirs from the Sandzak region hence his surname, or have Bosniak roots, they may have converted to Orthodox Christianity once arriving to Gjirokastër.
[4] All this was interrupted by the Islamic Revolt in Albania, and World War I. Kostandin was in Russia during the October Revolution, probably the only Albanian intellectual to have lived the events.
During this time, he kept friendship with other Albanian patriots and intellectuals as Fan Noli, Ymer Dishnica, Mirash Ivanaj, Halim Xhelo, Sejfulla Malëshova, Asdreni, Faik Konica, etc.
He was sent as ambassador to Sofia, Bulgaria (probably with Soviet support) but was recalled back in Albania prior to presenting his letter of credence to Bulgarian authorities; all this would remain an unclear and dubious situation.
He propagandized the fact that the Soviets prohibited a new partition of Albanian territories by making public the text of the Secret Treaty of London.

In May 1945, Joseph Earle Jacobs (1893-1971) as the representative of the US Civil Mission in Albania, would meet with Hoxha who back then was presenting himself simply as General-Colonel.
One of them was a permission for the United States Department of the Treasury representative Gardner Patterson (1916-1998) to visit Albania as part of his Balkan tour and place contacts with the Central Bank of the country.

The arrest and trial went on the same time the so-called "Group of the representatives" (Alb: Grupi i Deputetëve), several opposition members being sentenced, although Boshnjaku was not connected to them.
