The Kotromanić dynasty was a Bosnian ruling house that ruled during the Kingdom of Bosnia, perhaps the most important house of nobility in the country's history. They were sovereigns of medieval Bosnia and the surrounding lands, from the 13th century as Bans until the crowning and introduction of the Bosnian crown in 1377 and then as kings until the Ottoman conquest conquest in 1463.

Mehmed Spaho (born 13 March 1883 in Sarajevo – died 29 June 1939 in Belgrade) was a prominent and influential Bosniak political figure. He was the leader of the Yugoslav Muslim Organization.

Spaho received his primary and secondary education in Sarajevo before he studied law in Vienna. After he got his diploma in Vienna, he quickly gained an important political role.

Spaho was one of the most important members of the Bosnian Muslim community at the time. He was among the first Bosniaks to have an important political influence while Bosnia and Herzegovina was part of the Kingdom of Serbs, Croats and Slovenes.
