On 6 January 1929, using as a pretext the political crisis triggered by the shooting, King Alexander abolished the Constitution, prorogued the Parliament and introduced a personal dictatorship (known as the "January 6 Dictatorship", "Šestosiječanjska diktatura", "Šestojanuarska diktatura") with the aim of establishing the Yugoslav ideology and single Yugoslav nation. He changed the name of the country to "Kingdom of Yugoslavia", and changed the internal divisions from the 33 oblasts to nine new "banovinas" on 3 October. This decision was made following a proposal by the British ambassador to better decentralize the country, modeled on Czechoslovakia. A Court for the Protection of the State was soon established to act as the new regime's tool for putting down any dissent. Opposition politicians Vladko Maček and Svetozar Pribićević were arrested under charges by the court. Pribićević later went into exile, whereas over the course of the 1930s Maček would become the leader of the entire opposition bloc.
