[1] He transferred the fruits of Dubrovnik's cooperation to the level of Dalmatia when, on April 26, 1905, it was through his efforts that Dalmatian populists and moderate rightists merged into the Croatian Party, of which he immediately became president.

On September 20, in Dubrovnik, the Independent Organization of the Croatian Party was founded and headed by Čingrija.
