He was born to a family of tailors in Hnúšťa, Kingdom of Hungary. From 1834 to 1839, he studied at the "Evangelical Lyceum" in Levoča, then went to Pressburg, where he first met Štúr. In 1843, he passed the candidate's exam in theology and continued his studies at the law college in Prešov. He worked briefly as a deputy professor at the Lyceum, then became an aide to a member of the Gömör és Kis-Hont County Council.
In 1848, during the Slovak Uprising, he worked with Štefan Marko Daxner to organize the National Guard and was briefly sentenced to prison. After his release, he became a captain with the Slovak volunteers. After the revolution, he worked in Banská Bystrica, where he got married; then became a county commissioner in Debrecen from 1853 to 1859. While serving in several other official positions, he was the editor of Pešťbudínske vedomosti (a twice-weekly political journal based in Pest) from 1861 to 1863.
That same year, he became an honorary life vice-chairman of the Matica Slovenská. From 1864 to 1867 he was the county administrator of Liptó County, but resigned after the Austro-Hungarian Compromise. He then became chief superintendent and inspector of the gymnasium in Revúca. In 1872, he retired to Martin to become a full-time writer, where he died in 1905.
He also collected Slovak folk and fairy tales, translated Shakespeare, and helped edit collections of other writers' works, including those by Pavol Dobšinský and Jozef Škultéty. His son Miloslav Francisci became a composer who wrote the first opera in Slovak (Bohatieri veselej družiny, 1917).
