Bonacci Brunamonti's poetry explored conflicts, such as the 1859 Perugia uprising, the Battle of Magenta and the Battle of Solferino. As a devout Catholic, she dedicated some of her works to Pope Pius IX. Her poetry used classical metre and verse structures. Bonacci Brunamonti was forced to stop writing following a stroke in 1897.
