 Pessoa returned to his uncompleted formal studies, complementing his British education with self-directed study of Portuguese culture.The pre-revolutionary atmosphere surrounding the assassination of King Charles I and Crown Prince Luís Filipe in 1908, and the patriotic outburst resulting from the successful republican revolution in 1910, influenced the development of the budding writer; as did his step-uncle, Henrique dos Santos Rosa, a poet and retired soldier, who introduced the young Pessoa to Portuguese poetry, notably the romantics and symbolists of the 19th century.In 1912, Fernando Pessoa entered the literary world with a critical essay, published in the cultural journal "A Águia", which triggered one of the most important literary debates in the Portuguese intellectual world of the 20th century
