When the Austrian government recovered possession of Dalmatia in 1815, and with it of the town and territory of Republic, which had been incorporated with that province by Napoleon, Appendini was commissioned to establish a central institution at Zadar (Zara), for the purpose of creating teachers for the different educational institutes of the Dalmatia Province. He and his brother Urbano set to work but they experienced numerous obstacles to their plan. They went to Vienna in order to secure the support of the Austrian Emperor Francis I and his ministers, which they obtained and the school for teachers at Zadar was maintained.
